A quiet, careful
guide to Japan.
Yuki is trained on the parts of Japan a general chatbot skips — honorific register, visa timelines, JLPT tracks, seasonal travel, and the rhythm of daily life. Ask once. Get answers a resident would give.

003 · Use cases
Written for the people actually going.
First-time traveler
“Plan a 7-day Kansai loop that doesn't miss Nara but stays under ¥120,000.”
Yuki drafts a day-by-day route with train times, ryokan holds, and seasonal calls (autumn leaves peak in Arashiyama around Nov 18).
Language learner
“I'm N4 and I keep confusing に and で.”
Yuki teaches with side-by-side examples, quizzes you inline, and remembers the grammar points you've mastered across sessions.
Moving to Japan
“I want to move to Tokyo in 2028 as a backend engineer.”
Yuki builds a personalised roadmap — JLPT target, visa track, savings runway, prefecture comparison — and revisits it as your goals shift.
004 · Philosophy
“A general chatbot answers how do I move to Japan with a Wikipedia summary. Yuki answers with a year-by-year roadmap, references your saved goals, and shifts to keigo when a recruiter will read it.”
