Le Wagon Tokyo's 5-day AI Product Builder course runs September 28 to October 2 in Meguro, in English, for ¥190,000. Curriculum, cost, and fit.
Le Wagon Tokyo has launched an AI Product Builder course: five days, 40 hours, taught entirely in English at their Meguro campus. The first session runs September 28 to October 2, 2026, and tuition is ¥190,000.
It is not a coding bootcamp and it is not a job placement program. It is a short, intensive course on shipping a working AI product, aimed at people who already have an idea and want to stop waiting on someone else to build it.
We are sharing it because the skill gap it targets is one we see constantly. Plenty of people in Japan can describe an AI product. Far fewer can deploy one. Here is what the course covers, what it costs, and who it suits.
Key Takeaways
The premise is that building software no longer requires a team and a six-month runway. Someone with an idea and the right tools can get a working prototype in front of users quickly. Le Wagon's argument is that the useful question has shifted from "can I code?" to "can I build?"
The course is designed around that shift. It runs 40 hours across one week. Each day opens with an instructor-led session introducing the concepts, then moves into building. Most of the day is hands-on, with teachers and teaching assistants circulating to unblock people.
The output is a complete prototype. You finish the week with something deployed, not a certificate and a folder of notes.
Day 1: Low-Code AI. Platforms like n8n and Supabase, used to build AI agents and RAG (retrieval-augmented generation) pipelines.
Day 2: App Deployment. Moving past the front-end to deploy live, publicly accessible applications with working back-ends.
Day 3: Vibe Coding and AI Assistance. Using modern IDEs like Cursor and v0 to generate and debug full-stack code through prompting.
Day 4: AI Product Strategy. The "why" and "how" rather than the build itself: tech stack selection, compliance, and architecture.
Day 5: Build Your AI Product. Design, build, and pitch your own application. Le Wagon calls it the firework of the week.
Day 4 is the one worth flagging. Compliance and architecture are the parts most self-taught builders skip, and they are also the parts that decide whether a prototype can become something a company will actually run.
Le Wagon expects the room to be startup founders, product managers, consultants, designers, business professionals, and developers who want to work AI into what they already do. The common thread is wanting to build digital products rather than just use the ones other people built.
You do not need to be an expert coder. You do need a basic understanding of HTML/CSS and APIs, and accepted students complete 10 hours of prep work before the course starts.
A few things it is not, so you can judge the fit:
Tuition is ¥190,000 for the inaugural session. Admission is not automatic: there is an application, a short interview, and an AI fluency quiz.
The quiz is a reasonable signal about the format. A 40-hour week moves fast, and the screening exists so the room starts at roughly the same level. If you are accepted, budget the 10 prep hours honestly rather than showing up cold.
For context on what ¥190,000 represents locally, a single person in Tokyo needs roughly ¥200,000 to ¥280,000 a month to live comfortably, which we broke down in our cost of living in Tokyo guide. This is close to a month of expenses, so it is not a casual purchase.
Two things make this relevant to people job hunting in Japan.
First, it is taught entirely in English. English-language technical training in Tokyo is thinner on the ground than you would expect, and language is the most common blocker our readers hit. If you are still deciding how much Japanese you need, we wrote a longer piece on working in Japan without speaking Japanese.
Second, the gap between "understands AI" and "has shipped an AI product" is currently a real differentiator in interviews. A deployed prototype you can walk someone through is stronger evidence than a line on a resume. Japan's hiring market is tight across technical roles, which we broke down in our look at which jobs are most in demand in Japan.
We are not claiming the course leads to a job. But a portfolio piece you built and deployed yourself is a concrete thing to bring to a conversation, and it slots into the wider process we cover in our guide to getting a job in Japan as a foreigner.
We had the chance to put a few questions to Sylvain Pierre, CEO of Le Wagon Tokyo, about why the course exists now, what participants actually leave with on the Friday, and what the Tokyo community offers someone who has only just arrived. His answers are below.
Le Wagon Tokyo has been teaching here since 2016. What were you hearing from people in the community that made this five-day format feel like the right thing to build now?
There are three main realizations that led us to introduce this new AI Product Builder 5-day course.
First, a lot of people are contacting us saying "I want to learn AI". There are many aspects to learning AI, and we wanted to offer a shorter, more product-focused course to address one of these aspects.
Second, we're also noticing a shift in the kind of people who come to us: whereas the majority used to be career switchers, we now also talk to a lot of people who have a full-time job but feel the need to upskill, specifically with AI topics.
Lastly, many people who are interested in our courses do not necessarily have 9 weeks or 24 weeks to dedicate to it.
Day 4 is given entirely to AI product strategy: tech stack selection, compliance, architecture. Why was it important to you that the week include that, and not only the building?
Tech stack selection, compliance, architecture, and also most importantly, what to build!
AI-assisted coding is obviously commoditizing the product building aspect, which means that now, the core challenge is shifting from "how to build?" to "what to build?". We want to spend time with our participants to make sure they have a crystal clear vision for their product.
When it comes to architecture, tech stack and compliance, although your AI coding assistant will be able to make these choices during the bootstrapping phase, you'll need to know, or hire someone who knows, if you want to build at scale.
What does someone walk out with on Friday evening?
The short answer is whatever product idea they were dreaming of when they decided to join the course.
People with a Product Builder mindset come up with 2 to 3 ideas a day. We want to take them from these ideas to actually shipping a product that works.
It may sound simple, but very often people will write a prompt, get a landing page, tweak it a little, only to give up halfway through. Our goal is to bring them all the way to the finish line. We'll also be focusing on "selling" that product, which means knowing how to pitch it to clients.
From day one, Le Wagon has always embraced a "learn by doing" approach, and this approach works even better with AI tools: students need to experiment and learn empirically.
The Tokyo campus has welcomed students from more than 75 nationalities. For someone who has just moved here, what does becoming part of that community actually look like?
You are joining a Tokyo community of 1,500 Le Wagon alumni. This means having access to our campus, events and talks every week, exclusive job offers and connections with partner companies.
Like most communities, you'll get even more value out of it if you make the first step: whether you're looking for talented developers to help you with a project, specific mentorship to help with your career, or alumni working at your dream company.
Le Wagon has been running since 2013. By its own numbers, more than 30,000 students have graduated worldwide, alumni have launched over 200 startups, and those startups have raised more than one billion dollars combined. Treat those as company figures rather than audited ones.
The Tokyo campus opened in 2016 and has taken students from more than 75 nationalities. Sylvain Pierre puts the local alumni network at 1,500 people. The campus runs workshops, meetups, and talks most weeks.
Participants keep access to Le Wagon's learning platform after finishing, so the material stays available. They also join the global alumni Slack, where graduates trade job leads, questions, and projects.
For someone new to Tokyo, that network is arguably worth as much as the curriculum. Job leads in Japan move through people more often than through postings.

Do I need to speak Japanese to take this course?
No. The course is taught entirely in English, including materials and instruction.
Do I need to already know how to code?
Not to a professional level, but this is not a beginner course. You need a basic understanding of HTML/CSS and APIs, and there is an AI fluency quiz as part of admission. Accepted students also complete 10 hours of prep work beforehand.
Is this a coding bootcamp?
No. It is a five-day intensive focused on building and shipping AI products with existing tools. Le Wagon's 9-week full-time and 24-week part-time bootcamps are the programs for learning to code properly.
Can I get a visa to attend?
Yes, for the course itself. Le Wagon can help arrange a short-term visa so you can travel in and attend, as they do for their other courses. Worth being precise about what that is: it lets you come and take the course. It is not a work visa, it does not give you the right to work in Japan, and it is not a route to employment. If a work visa is what you are after, start with our guide to Japan work visa sponsorship companies.
Do I need to be in Tokyo to attend?
Yes for this session. It runs on campus in Meguro, Monday to Friday.
What do I finish the week with?
A working AI product you designed, built, deployed, and pitched, plus continued access to Le Wagon's learning platform and the global alumni Slack.
How much does it cost?
¥190,000 for the inaugural session running September 28 to October 2, 2026.
Applications go through the Le Wagon course page: info.lewagon.com/ai-product-building-course. The first session starts September 28, 2026, and admission includes an interview and a quiz, so leave time for it.
