Moving to Japan: The Five Layers of Japanese You Have to Acquire

Let me introduce myself before I start handing out advice.

I am Alejandro Pascual. I was born and raised in Mexico City. I came to Tokyo on a student exchange from the Tecnológico de Monterrey to Waseda University, expected to stay one year, and never went home. That was seven years ago. I attended Waseda entirely in Japanese, alongside Japanese students, in classes designed for Japanese students. I worked at Japanese startups conducting all business in Japanese. I founded my own company in Tokyo, 合同会社ボクセン (Boksen GK), and I run it in Japanese. I hold JLPT N1. I read manga in Japanese, watch anime without subtitles, and have business meetings in keigo on a weekly basis.

I am also a polyglot. I speak eleven languages. Japanese is the language I have spent the most years living inside. None of this is to flex. It is to tell you that the advice in this post is not theoretical. It is what I learned by hitting every wall personally and then watching hundreds of expat friends hit the same walls in the same order. (You can verify the resume on LinkedIn if you want to.)

Japanese does not acquire on a calendar. It acquires in layers. Most expat guides treat Japanese as a single skill that gets better over time, like running. It is not. Japanese is closer to a stacked set of competencies, each with its own unlock, vocabulary, register, and trap. The layer you need on day one is not the layer you need at month six, and the layer you need at month six is not the layer you need to argue politely with your landlord in year two. Get the layers in the wrong order and you spend years sounding fluent at the wrong register for every situation.

Below are the five layers, in the order they unlock, with the work each one demands.

Layer 1: Recognition (the keigo wall in the first ten seconds)

The first layer is not vocabulary. It is recognition of the register your environment defaults to before you produce a single sound.

Japanese has three layers of formality, and almost every interaction you will have in Japan as a new expat happens in the upper two layers, not the lower one your app taught you.

丁寧語 (teineigo) / polite form. This is です/ます. Your textbook and Duolingo cover this. It is the floor of polite Japanese.

尊敬語 (sonkeigo) / respectful form. This is what people use when referring to the actions of someone they respect. お飲みになる / 召し上がる both mean "to drink/eat" but referring to a respected other.

謙譲語 (kenjōgo) / humble form. This is what people use when referring to their own actions in the presence of someone they respect. いただく (humble "to eat/drink/receive") 申し上げる (humble "to say") 拝見する (humble "to look").

Every restaurant, every hotel, every shop, every train station, every bank, every airport counter, every customer-service phone line, every doctor's office, every ward office, every department store, every taxi driver, every delivery person who comes to your door, every government employee, and most of your future coworkers in any role with seniority will use a mix of sonkeigo and kenjōgo when they speak to you. Not because they think you are special. Because that is the default register for any service or hierarchy interaction in Japan.

You do not need to produce keigo on day one. You need to recognize it on day one. The difference between recognizing お席へご案内いたします (kenjōgo: "I will humbly guide you to your seat") and parsing it as gibberish is the difference between feeling like an adult in Japan and feeling like a tourist in your own home.

Here is where every other Japanese learning app fails you. Almost every app I have tested gates keigo behind their advanced curriculum. Duolingo barely touches it. Babbel skips it in beginner content. Rosetta Stone never gets there. Even Genki II only introduces keigo in the final chapters and Minna no Nihongo treats it as N3-level. The conventional wisdom is that keigo is too advanced for beginners. That is right for a hypothetical Japanese-major sophomore in Iowa with five years before they need to function in Tokyo. It is catastrophically wrong for the thirty-five-year-old who lands at Narita next month and is ordering at restaurants and signing forms within forty-eight hours.

Service-Japanese: what Layer 1 actually demands

Almost every service interaction you will have in Japan opens with one of a small set of stock keigo phrases. Memorizing these for recognition will instantly upgrade your first-week-in-Japan experience.

Three observations on the table above.

First, none of these are in your beginner curriculum. By the time Genki II finally introduces keigo in chapter 19 or 20, you have already been fluent in expat life for ten months. You needed these phrases on day one.

Second, you do not need to produce most of these. You need to recognize them, parse what is being asked of you, and respond with です/ます-level Japanese. かしこまりました directed at you means "understood" and you can respond with はい、お願いします. You are not expected to fire keigo back. You are expected to understand it.

Third, 大丈夫です is its own universe. It can mean "I am fine," "no thank you," "that's okay," "no, that won't be necessary," "yes please," depending on context, intonation, and the question. I have seen expats decline help they desperately needed because they said 大丈夫です without realizing it can be a polite refusal. I have seen them agree to extra services they did not want by saying 大丈夫 in response to "can I add cheese?". The fix is not to memorize a translation. The fix is to live in the language enough to feel the context.

Layer 1 unlocks when: every keigo phrase in the table above parses on first hearing without you needing to slow it down in your head. Most expats hit this between week 6 and week 12 with focused practice.

Layer 2: Transactional (the bureaucratic gauntlet)

The second layer is the Japanese that runs your paperwork. It is dry, kanji-heavy, kanji-readable rather than kanji-writable, and almost none of it is in your textbook.

Within fourteen days of moving in, you must enroll in 国民健康保険 (if not employed) or 健康保険 (through your employer). This is mandatory. The 区役所 will set this up. Bring your residence card, your hanko, and your bank account info.

That ward office trip is the start of a roughly thirty-day bureaucratic gauntlet that decides whether your first six months feel manageable or hostile. The vocabulary below is what you will meet, in roughly the order you will meet it.

Memorize these for recognition before you land. The first time you walk into a 区役所, you do not want to be Google-translating 住民票 on your phone. You want to know the word, the rhythm of the conversation, and what to expect.

Layer 2 hoops nobody warns you about

These are the friction points I have personally walked through and watched friend after friend hit. The visa websites do not mention them.

The hanko / 印鑑 procurement saga. Despite Japan's push toward digital signatures since 2021, hanko remain required for many contracts, bank accounts, and some government forms. Foreigners need to order custom katakana ones; Tokyu Hands, Don Quijote, and specialty shops do them. Cost: ¥1,500 to ¥10,000. Time: same-day to one week. Get this done in your first two weeks.

The phone contract rejection. Major carriers (Docomo, au, Softbank) sometimes reject new foreigners without 90+ days of residency or Japanese credit history. Workaround: Rakuten Mobile, IIJmio, Y!mobile are foreigner-friendly. Bring your residence card, bank info, a Japanese phone number for verification (yes, the catch-22 is real), and patience.

Bank account opening. Yucho (Japan Post Bank) opens accounts for new foreigners on day one, no minimum stay required. Mizuho, MUFG, SMBC sometimes require six months. Shinsei is foreigner-friendly with English support; Sony Bank is online-only English. Open a Yucho first, then graduate to a city bank after 6+ months.

Apartment hunting and the "no foreigners" reality. Some landlords still refuse foreign tenants and the legal protection is weak in practice. Workaround: foreigner-friendly agents (Plaza Homes, Sakura House, Apts.jp, Tokyo Apartment Inc). Expect to need a 保証会社 (guarantor company) adding 50-80% of one month's rent. Budget 敷金 (1-2 months) + 礼金 (0-2 months) + 仲介手数料 (1 month) + 保証会社 fee + first month: typically 5-7 months of rent upfront.

The NHK collector at the door. NHK has door-to-door fee collectors. The legal status of mandatory payment is contested. Many expats are surprised the first time someone knocks insistently asking them to sign up. You can decline. 結構です or 契約しません is sufficient.

The gomi (trash) schedule. Every neighborhood has a specific schedule for burnable, non-burnable, recyclables (PET bottles, cans, paper), and oversized items. Your neighbors will judge you for getting this wrong. The judgment is silent but real.

Layer 2 unlocks when: you can walk into a 区役所 with a stack of documents, identify the correct counter, file the correct form, and leave with the correct certificate without translation help. Most expats hit this around month 3-4.

Layer 3: Relational (casual register and small talk)

The third layer is the Japanese that builds friendships. It looks easier than Layer 2 (no kanji-heavy forms) and is actually harder, because the rules are unwritten.

Casual register (tameguchi) emerges from です/ます as you stop sounding like a textbook. 〜だ (instead of です), 〜じゃん, 〜だよね, 〜けど, 〜から. You start using contracted forms (〜なきゃ for 〜なければならない, 〜ちゃう for 〜てしまう).

The unwritten rules: when to drop です/ます with a colleague (when they drop it with you first, never unilaterally), when senpai dynamics override casual register (always, in any work context), when uchi/soto (in-group/out-group) shifts the register mid-conversation, when silence is the correct response (often), when ちょっと… with a trailing pause means "no" (usually).

Around the eight-week mark you start to notice that the conbini interaction stops feeling like a panic attack. That is Layer 1 firming up. Around month 4-6, conversations with the same coworker over weeks start losing their textbook stiffness. That is Layer 3 starting.

The vocabulary of Layer 3 is mostly fillers and softeners.

• まあ, sort of, kind of, well
• ちょっと, a bit (often a softener that means "no" without saying so)
• なんか, like, somehow, a discourse marker
• やっぱり, as expected, after all
• 結構です, that is fine (often a polite refusal)
• 別に, not particularly (often "no" with attitude)
• ですよね, isn't that so (confirms shared knowledge)
• そうそう, yeah yeah (active listening)
• なるほど, I see (active listening, slightly older register)
• へえ, oh really (active listening, neutral)

The Japanese conversation flows on these. If you have not internalized them by Layer 3, your speech sounds robotic even when grammatically correct.

Layer 3 unlocks when: a Japanese acquaintance switches from です/ます to tameguchi with you mid-conversation and you flow with the switch without freezing. Most expats hit this somewhere between month 6 and month 12.

Layer 4: Professional (the keigo you produce, not just recognize)

Layer 4 is the Japanese that lets you work inside a Japanese company at a level higher than English-speaking foreigner. By now you produce です/ます confidently. You need to produce sonkeigo and kenjōgo correctly when context demands.

Email Japanese is its own micro-skill. お世話になっております opens almost every business email. よろしくお願いいたします closes it. ご確認のほど、よろしくお願いいたします is the email "please confirm." お忙しいところ恐れ入りますが is the email "sorry to bother you, but." ご連絡が遅くなり申し訳ございません is "sorry for the delayed reply." These are templates, not creative writing.

Meeting Japanese is its own register again. 本日はお時間をいただきありがとうございます opens a client meeting. よろしくお願いいたします closes it. Self-introduction (自己紹介) follows a fixed format: company, role, what you do, よろしくお願いします. Disagreement is indirect: 少し検討させていただきます ("let me consider a little") often means "no." 難しいかもしれません ("it might be difficult") often means "no." 持ち帰って検討します ("let me bring it back and consider") often means "no after I save face."

Keigo production is the hardest skill in Japanese. You will get it wrong for years and Japanese coworkers will silently note it. The path to Layer 4 is hundreds of work-context reps with feedback. A Japanese coworker willing to gently correct your keigo is the highest-value relationship you can build inside a company.

Layer 4 unlocks when: you can write a client email in correct keigo without proofreading, run a customer meeting without code-switching, and read a contract without translation. Most expats hit this at year 2-3 if they work in a Japanese-language environment, never if they stay in the English bubble.

Layer 5: Integration (the layer the bubble cannot give you)

Layer 5 is the Japanese that stops being a project and becomes a way of being. By Layer 5, you do not "speak Japanese." You think in Japanese for hours at a time. You catch jokes. You react to keigo automatically rather than parsing it consciously. You read kanji on signs without thinking. You overhear train conversations and realize you got the gist.

I want to say something directly that nobody else says.

Roppongi, Hiroo, Azabu, Aoyama, Hiroo International School zone, the Tokyo American Club, and the corporate-relocation Hilton-and-driver world: you can live inside this bubble for ten years and never reach Layer 5. I have met expats who did exactly that. They had successful careers, raised families, retired in Tokyo, and never crossed the Japanese-language threshold.

It is a choice. I will not judge it. The cost is that the Tokyo that does not require Japanese is also the Tokyo that does not really feel like home. People who learn Japanese, even imperfectly, end up with a different country than the one the bubble residents live in. They have Japanese friends. They get the small jokes. They follow the news. They understand the layer of social meaning underneath every interaction. They feel like adults in their own city.

This fork shows up around year 1 because the relocation chaos has finally settled. The lease, the bank, the phone, the ward office all work. You finally have spare cognitive bandwidth and have to decide what to spend it on. The expats who reached Layer 5 made it a non-negotiable habit in this exact stretch. The ones who gave up decided "I will pick it up later" and then never did.

Layer 5 unlocks when: you have a Tuesday like any other in Tokyo and you do not notice it was a Japanese day at all. That is the moment Tokyo stops being abroad and starts being home. For an expat doing 30 to 45 minutes a day with a structured app, one or two weekly tutor sessions, and daily Japanese exposure, expect 9 to 12 months for Layer 1 + Layer 2 functional, 18 to 24 months for Layer 3 comfortable, and 3 to 5 years for Layers 4 and 5. The FSI classifies Japanese as a Category IV language at roughly 2,200 hours to professional working proficiency. Living in Japan compresses that timeline if you stay out of the English bubble. Target N4 (around 600 hours) in your first 12 to 18 months and N3 (around 1,000 hours) by year 2 to 3.

Where you live affects which layers bite hardest

Tokyo / Kanto (関東弁). Standard Japanese. If you are in Tokyo, Yokohama, Saitama, or Chiba, this is what you live in. The Mynago default. Layer 1 and Layer 2 are straightforward here because the textbook matches the street.

Osaka and Kansai (関西弁). Different intonation, different vocabulary, different sentence-final particles. 〜やん instead of 〜じゃん, めっちゃ instead of とても, ほんま instead of 本当, あかん instead of だめ, ちゃう instead of 違う, 〜へん instead of 〜ない. Layer 3 splits in Kansai: you need standard Tokyo Japanese for work and Kansai-ben for daily life.

Kyoto (京都弁). A subset of Kansai but softer, more indirect, famous for layered politeness where surface meaning and intended meaning often diverge. Layer 3 is hardest in Kyoto because the indirectness is famously hard for outsiders to read.

Hakata / Fukuoka / Kyushu (博多弁). Distinct intonation, 〜と and 〜とよ and 〜ばい sentence-finals. Fukuoka is increasingly an expat destination for cost-of-living refugees from Tokyo.

Okinawa (沖縄方言) is historically a different language family. Hokkaido (北海道弁) stays close to standard with distinctive slower pacing. Tohoku (東北弁) is heavy contraction and slurred consonants, the hardest regional variant for outsiders.

English-bubble depth by city

The English bubble in Tokyo exists in Roppongi, Hiroo, Azabu, Aoyama, Omotesando, parts of Shibuya, parts of Shinjuku, the international school zones in Hiroo and Mejiro, and the embassy circuit. Cross into Setagaya, Suginami, Bunkyo, Toshima, Ota, or Kita and English drops to near zero. Osaka, Kyoto, Fukuoka, Nagoya, Sapporo all have less English than central Tokyo. Okinawa has tourist English in Naha plus a separate English-speaking US-military-base ecosystem. Smaller cities and countryside drop to near zero English. If you are buying a 空き家 in Wakayama or Nagano for ¥1 million, your daily Japanese requirements are the highest in the country.

If you have flexibility, Tokyo gives you the longest soft-landing runway. The English bubble is largest. If you are settling outside the central five wards, treat your first 90 days of Japanese as urgent rather than optional.

The 2024 visa reforms that opened the door

Before you read further, you need a sense of why the wave is arriving right now.

The 2024 visa reforms. Japan's J-Skip (Special Highly Skilled Professional) and J-Find visas, the expanded Skilled Worker categories, and the Digital Nomad Visa launched in April 2024 opened the country in a way nobody who lived here in the 2010s would have predicted. Tokyo specifically is now actively recruiting foreign founders, foreign engineers, and foreign skilled workers.

The yen. The dollar-yen rate sat above 150 for most of 2024 and 2025 and is projected to remain weak into 2026. For US-salaried remote workers, Tokyo went from one of the world's most expensive cities to one of the most cost-effective major Asian capitals.

The aging population. Japan's working-age population is shrinking by roughly half a million people per year. The country needs foreign workers structurally.

The new wave is broader. It used to be English teachers in regional cities and finance bros in Roppongi. Now it is families in Setagaya, founders in Shibuya, post-pandemic remote workers in Nakameguro, retirees buying countryside houses in Nagano and Wakayama, and skilled workers across every industry. The country welcomes all of them. The Japanese language does not bend to accommodate them.

How Mynago fits the five layers

This is my app, so take this section with that context.

I built Mynago partly because I had spent seven years watching expat friends in Tokyo grind through the wrong layer first. The standard advice ("study Genki, then Genki II, then Tobira, then start consuming native content") works for university students with five years to spare. It does not work for a thirty-five-year-old engineer arriving on a Skilled Worker visa next month.

Mynago handles the layer sequencing differently in five concrete ways.

1. Layer 1 (recognition) from lesson one. When you tell us at onboarding that you want to practice ordering at restaurants, booking medical appointments, opening bank accounts, or any other situation where keigo is the actual register, we generate lessons that include keigo recognition from your first session. Not as a centerpiece grammar lesson. As realistic Japanese you would actually hear, with the appropriate plain-form response you should give back. No other major app does this.

2. Layer 2 (transactional) targeted to your situation. Lessons target concrete situations: ordering omakase, asking the doctor about a prescription, talking to your real estate agent about 敷金 and 礼金, picking up a Yamato package, navigating the ward office for 住民票 registration.

3. Tokyo-region audio for accent calibration. Native pacing, native intonation, real Tokyo accent. Not the slowed-down classroom voice.

4. Cultural notes anchored to real Japanese life. Why 大丈夫です can mean "no thanks" instead of "I'm fine." Why 元気ですか sounds robotic in real life. Why すみません does the work of "excuse me," "sorry," and "thank you" depending on context. Why your Japanese coworker says ちょっと… and trails off when they mean "no". Written by someone who lives in this register daily, not by a content marketer.

5. Hanja, kanji, and word-origin support. For learners coming from Chinese or Korean backgrounds, kanji bridges accelerate vocabulary learning dramatically.

What Mynago does not do, honestly: it does not replace a tutor (for Japanese specifically, finding a 1-on-1 tutor on iTalki, Preply, or NativShark for one or two sessions a week is the highest-ROI thing I can recommend). It does not replace immersion. It does not replace WaniKani for kanji. And it is not a Genki replacement for university Japanese majors.

If you have read my Learning Japanese or Best Apps to Learn Japanese posts, the framing here is the same. Mynago is the daily core engine for the expat use case. WaniKani for kanji, a tutor for correction, immersion for the ear, Mynago for the daily situational practice.

What apps cannot do

No app will make you fluent in Japanese. Apps make the work efficient. They do not eliminate it. Pair Mynago with: a tutor on iTalki, Preply, Cafetalk, or NativShark for one or two 60-minute sessions a week ($10 to $20 USD per hour); Japanese drama with Japanese subtitles, not English (Midnight Diner / 深夜食堂, Terrace House, Tokyo Vice, Hanzawa Naoki, classic Studio Ghibli, plus adult-oriented anime like Vinland Saga, Mushishi, Monster); Japanese podcasts (Nihongo Con Teppei, Bilingual News, Yuyu Nihongo Podcast); a language-exchange partner via Tandem, HelloTalk, or one of the dozens of Tokyo Meetups; and the most underrated tutors in Japan, your neighbors, your conbini staff, and your soba shop owner. Order in Japanese even when the menu has English. Ask for directions in Japanese even when you could pull up Google Maps. The cost of looking briefly silly is the price of becoming functional.

If you want to start now, Mynago supports Japanese with keigo from lesson one when you tell us your context. The lessons are free to start. The 2,200 FSI hours are real. The seven years I have spent here are also real, and I can tell you with conviction that the Japanese is the difference between a year in Tokyo and a life in Tokyo.
