証言 — TESTIMONY. THE STORY OF WHAT REALLY HAPPENED.
SHOGEN is a home for interrogation mysteries built for people learning Japanese. Ask real questions, get instant, natural corrections as you write, and solve a case from the inside — instead of drilling flashcards, you'll be having a conversation you actually care about the outcome of.
Every character is AI-driven and improvises honest answers to whatever you ask — no dialogue trees, nothing memorized.
Sensei mode checks every sentence you write and shows you the natural way to say it, right as you're writing it.
Every case adapts to you — from simple N4 beginner Japanese up to full native-speed N1, with dialect and nuance.
Tap any word in the dialogue for its reading and meaning. It's saved straight to your personal word list.
One tap plays native pronunciation, so you can hear a line the same way you just read it.
Close a case and get a short, personal write-up: what you did well in Japanese, and what to practice next.
The shrine's sacred mirror has vanished the night before the summer festival. Question three villagers to find it before dawn.
Ten million yen has disappeared from a locked safe after a night club's biggest event. Everyone has a story — one of them is lying.
SHOGEN is an in-progress project. Story details and features shown here are subject to change before launch.
