Only 6% of Coto Academy's students are on student visas. Evening and weekend Japanese classes for working professionals in Tokyo and Yokohama, from ¥20,000 a month.
Most Japanese language schools in Tokyo are built for one type of student. Someone in their early twenties, here on a one-year student visa, free between nine and five.
If you already have a job in Japan, that model does not work. You cannot attend a class that meets every weekday morning. Finding a Japanese language school in Tokyo built for working professionals is a narrower search than it looks.
Coto Academy takes a different approach. It offers both intensive and part-time general Japanese classes, with lessons available throughout the week and on Saturdays. For more specialized needs, it also offers Business Japanese classes mainly on weeknights from 19:10 to 21:00 or on Saturday afternoons. You pick the classes that fit around your workday and commute.
The student body reflects that. By Coto's own published figures, 43.68% of its students are aged 25 to 34, and another 26.95% are 35 to 44. Roughly half hold a work visa, a spouse or dependent visa, or permanent residency. These are people who live here.
The standard Japanese language school in Japan is designed around the student visa. To hold student status you must attend a school designated by the Minister of Justice. Language institutes are separately screened for that purpose, as Japan's official Study in Japan portal sets out. Full-time daytime attendance is what that track is built to evidence. So the default timetable is weekday mornings, five days a week, for a year or two.
It is a sensible design for the students it was built for. It is useless if you are in an office at 10:00 on a Tuesday.
This creates a specific problem for foreign professionals in Japan. You are the person who most needs functional Japanese, because you are staying. But you are the person the timetable excludes.
Coto Academy exists because someone noticed that gap early. By its own account, the school started in 2000 as a group of volunteer Japanese teachers. They ran lessons out of an Iidabashi apartment, helping international residents settle in. Iidabashi is now the flagship school. The founding idea, teaching Japanese for real daily situations rather than textbook drills, is still the thing the curriculum is organised around.
Twenty-five years on, Coto reports having taught more than 15,000 students from over 50 countries across 60-plus courses.
Four formats matter if you are working. They differ in intensity, not in quality.
The flexible option. Per Coto's part-time course page, lessons run 50 or 100 minutes, and you choose how many you take per week. Availability spans 9:00 to 21:00 on weekdays and 10:00 to 17:00 on Saturdays. An evening or weekend schedule is genuinely possible, not just theoretically possible.
All levels are covered, from complete beginner to advanced. You can join at any point in the year. There is no minimum enrollment period, which is unusual among Japanese language schools and matters if your workload is unpredictable.
The course to look at first if your reason for studying is work. Coto's Business Japanese course page lists it as part-time. It runs mainly on weeknights from 19:10 to 21:00 or on Saturday afternoons, at the Tokyo and Yokohama campuses and online.
The content is workplace-specific: keigo, business vocabulary, email and phone etiquette, meeting language, negotiation, and client-facing conversation. Advanced levels move into high-stakes situations where precision matters.
Levels run from beginner-intermediate up to advanced, mapped against JLPT bands. That entry point is a deliberate choice on Coto's part. Business communication is treated as something to start early rather than a reward you unlock at N2. If you have sat silently through a meeting you half-understood, you already know why that argument holds.
A middle gear. It meets twice a week for 100 minutes, with the same 9:00 to 21:00 weekday and Saturday availability as part-time classes. You get the structured progression of an intensive curriculum without surrendering your working week.
The traditional full-time track, set out on Coto's intensive course page. Monday to Friday, 150 minutes a day. Mornings run 9:30 to 12:20 in Tokyo and 9:10 to 12:00 in Yokohama; afternoons are 14:10 to 17:00 everywhere.
This one does not fit around a full-time job. It is worth knowing about anyway, because there are moments when it makes sense. A gap between contracts. A stretch of leave before a job hunt. A hard deadline like a JLPT sitting or a visa application.
| Format | Schedule | Session length | Fits a full-time job? |
|---|---|---|---|
| Part-time | Weekdays 9:00 to 21:00, Sat 10:00 to 17:00 | 50 or 100 min | Yes |
| Business Japanese | Mainly weeknights 19:10 to 21:00, Sat afternoons | 50 or 100 min | Yes |
| Lite Intensive | Twice weekly, same hours as part-time | 100 min | Yes |
| Intensive | Mon to Fri, mornings or afternoons | 150 min | No |
Every format caps classes at 8 students and is taught by native Japanese instructors. Coto's teaching approach is conversation-led, so a small room is not a detail. In a class of 8 you speak. In a class of 25 you listen to other people speak.
This is where the positioning stops being a claim and starts being data. Coto publishes a full student demographic breakdown, and it does not look like a typical language school roster.
By age, the centre of gravity sits squarely in working years:
| Age group | Share of students |
|---|---|
| Under 18 | 2.33% |
| 18 to 24 | 12.17% |
| 25 to 34 | 43.68% |
| 35 to 44 | 26.95% |
| 45 to 54 | 9.67% |
| 55 and older | 5.20% |
Seventy percent of the room is between 25 and 44. The classic gap-year demographic, 18 to 24, is barely one student in eight.
By residence status, the picture is even clearer:
| Status | Share of students |
|---|---|
| Work visa | 28.80% |
| Tourist | 28.27% |
| Dependent or spouse | 12.41% |
| Other | 11.85% |
| Permanently living | 8.94% |
| Student | 6.03% |
| Working holiday | 3.69% |
Add work visas, spouse and dependent visas, and permanent residents together and you get roughly 50% of the student body. Only 6.03% are on student visas. Walk into a Coto classroom and the person beside you is more likely a working colleague than a classmate.
By origin, students come from more than 50 countries and regions. Asia accounts for 29.1%, North America 28.2%, Europe 26.2%, Oceania 5.9%, and other regions 7.8%. North America and Europe together make up 54.4%.
By starting level, 53.05% arrive as beginners and 20.30% as upper beginners. You are not walking into a room of people who have been studying since high school.
One more number worth having: 68.2% study in person in Tokyo or Yokohama, and 31.8% study online. The online option is real, and a third of students use it. That matters if you live outside the commuter belt, or your schedule moves week to week.
Five physical locations, all chosen for commuter access: Shibuya, Shinjuku, Iidabashi, Minato (the Azabu-Juban Coto Club), and Yokohama. Online classes run alongside them.
The geography is the point. A 19:10 class only works if the school sits on a line you already ride. Shibuya and Shinjuku cover most of the western commute. Iidabashi serves central Tokyo, Minato covers the embassy and finance districts, and Yokohama handles the southern corridor. Still choosing where to live? Our guide to the best neighborhoods in Tokyo for expats covers the same commuter logic from the housing side.
Coto charges a one-time ¥10,000 registration fee for new students. After that you choose between a monthly subscription and a lesson package. Figures below are from Coto's part-time and intensive course pages, retrieved 26 August 2026.
| Plan | Price | What you get |
|---|---|---|
| Trial | ¥3,200 | 1 lesson |
| Starter | ¥20,000 per month | 2 lessons per week |
| Middle | ¥36,800 per month | 4 lessons per week |
| Growth | ¥50,400 per month | 6 lessons per week |
| Package | ¥43,200 | 16 lessons |
| Package | ¥83,200 | 32 lessons |
| Package | ¥120,000 | 48 lessons |
| Package | ¥230,400 | 96 lessons |
Intensive pricing works differently: roughly ¥40,000 for one week, ¥136,000 for four weeks, and ¥360,000 for twelve. Enrolling six or more weeks ahead earns a 10% early-bird discount, and the registration fee is waived on enrollments of three months or more.
For context, a single person in Tokyo needs roughly ¥200,000 to ¥280,000 a month to live comfortably. We broke that down in our cost of living in Tokyo guide. The ¥20,000 Starter plan is a real line item in that budget. It is not in the same category as full-time tuition.
The ¥3,200 trial lesson is the sensible first move. It costs less than a dinner out and tells you whether the format works for you.
Coto has expanded into two adjacent services, and both are worth knowing about because they solve problems Coto Academy itself does not.
Coto Japanese Institute is the full-time, visa-sponsoring option. It is MEXT-accredited and provides student visa support, which Coto Academy does not. Its two main tracks are Practical Japanese and Career Readiness (JLPT N5 to N3) and Advanced Japanese Communication and Career Growth (N3 to N2). There are also six-month short courses for people already resident here. The framing is career-focused rather than university-preparatory, and its students are mainly in their twenties and thirties. If you need a visa route in order to study, this is the door.
Coto School Finder (studyinjapan.org) is a free school-matching service. It shortlists schools against your goals, budget, and timeline, and handles student visa paperwork including the Certificate of Eligibility. Its partner list extends well beyond Coto, including Toyo Language School, Communica Institute in Kobe, and schools in Fukuoka and other regions. It is genuinely useful if you are not yet in Japan and do not know where to start.
Worth being precise here. Studying at Coto Academy does not give you the right to work in Japan. Language study is not a visa route on its own. If a work visa is what you need, start with our guide to Japan work visa sponsorship companies.
Honest answer: it depends on the role, and less than people assume at the entry point.
You can get hired in Japan without Japanese. Plenty of engineering, product, and research roles run in English. We covered the realistic version of that in our piece on working in Japan without speaking Japanese. Do not let a language gap stop you from applying.
What changes with Japanese is the size of the pool and the shape of your day. More roles open. Internal meetings stop being something you reconstruct afterwards from a colleague's summary. Promotion conversations get easier, because the people deciding can assess you directly rather than through an interpreter.
It also changes interviews. Even conversational Japanese in an otherwise English-language interview reads as commitment to staying, which is a real concern for Japanese employers evaluating foreign candidates. Our breakdown of Japanese job interview questions covers what that assessment looks like from the other side of the table.
If work is your motivation, Business Japanese beats a general conversation class for one reason. It targets the specific register you are missing. Ordering food and running a project meeting are different skills. Most people arrive fluent in neither, and general courses only fix the first.
Two reasons, and one caveat.
The first is that "how much Japanese do I actually need?" is the single most common question we get from readers. The honest answer changes depending on whether you can study around a job. A school that only teaches at 10:00 on a Tuesday is not an option for most of the people we talk to. Coto is one of the few in Tokyo whose timetable assumes you are employed.
The second is that Coto publishes its student data openly. Most language schools describe their student body in adjectives. Coto puts percentages on a public page, which means claims about who studies there can be checked rather than taken on trust.

Can I study at Coto Academy while working full time in Japan?
Yes. That is the case the school is built for. Business Japanese runs mainly on weeknights from 19:10 to 21:00 and on Saturday afternoons, and part-time classes are available from 9:00 to 21:00 on weekdays. Nearly half of Coto's students hold a work, spouse, dependent, or permanent residence status.
Do I need to already speak Japanese to enroll?
No. Just over half of Coto's students, 53.05%, start as complete beginners, and another 20.30% start as upper beginners. Courses run from zero through advanced.
Can Coto Academy sponsor a student visa?
Coto Academy itself does not sponsor student visas. Coto Japanese Institute, the MEXT-accredited school in the same group, does provide student visa support. Coto School Finder can also handle Certificate of Eligibility paperwork for partner schools.
How much does it cost to start?
A single trial lesson is ¥3,200. Regular study starts at ¥20,000 a month for two lessons a week, plus a one-time ¥10,000 registration fee for new students.
Do I have to commit to a fixed term?
No. There is no minimum enrollment period, and you can join at any point in the year. This is one of the clearer differences between Coto and schools built around the student visa calendar.
How big are the classes?
Eight students maximum, across every format. Classes are conversation-led and taught by native Japanese instructors.
Is there an online option?
Yes, and 31.8% of Coto's students use it. The remaining 68.2% attend in person in Tokyo or Yokohama.
Which course should I take if I want Japanese specifically for work?
Business Japanese. It covers keigo, email and phone etiquette, meeting language, negotiation, and client conversation, and it opens from beginner-intermediate rather than requiring an advanced level first.
The lowest-risk entry point is the ¥3,200 trial lesson, combined with Coto's free online level check so you land in the right class. Course details and enrollment are at cotoacademy.com.

Housing is where foreign residents report the most discrimination in Japan. What you pay upfront, how guarantor companies screen you, and how to get approved.
Japan caps overtime at 45 hours a month, backed by criminal penalties. Full-time workers average 13.2 hours, but transport runs three times manufacturing.
