Overview

A conversation-first Japanese app for heritage learners. Instead of a robot chatbot, it's built around the native speaker you already have at home — giving you one small thing to say at dinner each day — and the relatives you want to understand on your next visit.

The Problem

I'm half Japanese. I grew up around the language — relatives in Yamagata, Japanese spoken at home sometimes — but we always defaulted to English, and here I am. Every app I've tried is built for tourists, anime fans, or JLPT test-takers, and I quit all of them. What I actually want is to hold a real conversation with my family.

Built For

Heritage learners with a Japanese family member at home — people who want family connection, not a test score.

Key Features

The table is the lesson

Activates the native speakers already at your table. Each day gives you one un-awkward thing to say at dinner and gently opens the door to a reply in Japanese — real native interaction from day one, no robot.

Ears before eyes

Listening-first: you hear every phrase in a real voice before you ever see it written. Kanji and reading come later — understanding family at the table comes first.

The road to Yamagata

Every phrase ladders up to a concrete, emotional goal: the next reunion. A countdown and per-relative goals turn abstract 'study Japanese' into 'be ready to talk to Grandma.'

Progress you can feel

No points or leaderboards. It counts real conversations had and things you understood — engineered for the month-3 'valley of despair' where motivated learners usually quit.

The right register

Casual warmth at home, gentle keigo for older relatives. Teaches the politeness levels that actually matter for family — the part textbooks and tourist apps skip.

Why It Wins

Better than: Duolingo WaniKani Bunpro LingoDeer HelloTalk
  • Built for heritage learners (family connection), not tourists, anime fans, or JLPT test-takers
  • Uses the learner's own family as native-speaker practice — the one thing no app can replicate
  • Listening/speaking-first instead of text/reading-first — matched to the real goal of talking
  • Progress measured in real conversations, not streaks — designed to survive the month-2-to-4 dropout window
  • Grounded in language-acquisition research (comprehensible input, SRS at 85–90%, Fogg habit model)
