Education, training, consulting; plus education products. Based in Japan.
Isen. Based in Japan, working across AI education, training, and consulting. Two main threads — train people who wield AI as a weapon, and reshape learning through AI.
On the first thread: AI Jissen Juku for students and career-switchers, Programmer AI for working engineers, and Enterprise AI Training for companies. Thirteen real-world scenarios are the shared backbone — each programme is tailored per audience.
On the second: Hoshimikan, an exam-prep platform. The starting point of every product is the same question — "Can this be made into a tool someone can pick up and use right away?"
Three threads — AI Education Solutions, AI-Powered Education, and AI Tools. Each card opens its own destination.
Train people who wield AI — from non-engineers to working developers to enterprise teams.
Pick one of 13 real-world scenarios; design, implement, test, and present it across 8 weeks. Finish with a real-world piece you can put on a résumé.

→Visit↗Drop in a note, a link or a photo — get multi-page RED cards, JP/EN Instagram cards and matching image / video prompts. Edit inline, save drafts to the cloud.
→Visit↗Type the headline, pick a ratio and a layout, and it sets itself. Drop in a background image, mix CJK and Latin faces, export a PNG or record the canvas.
→Visit↗Words and weights settle into a cloud — spiral, columns, scattered hand, grid, physics or a turning solid. Pour the type into a photo or an .obj model, stamp a seal, export SVG, PNG or GIF.
→Visit↗Engineering notes and build-log fragments, scattered across external platforms.
