疑問に、はっきり答える
The essentials about the free resources, 達人 (Tatsujin), books, and what happens when you register an email.
QUICK PATHS
If you want quick study, go to Free Resources. If you want to actually remember and use phrases, try 達人 (Tatsujin). If you want the deeper explanation behind the teaching, open the books.
USEFUL LINKS
The site separates PDF learning, app learning, books, and videos so you can get to the right place without guessing.
Learners who already know basic grammar and vocabulary, but still want to understand real conversation, sharper nuance, and more natural phrasing.
No account is needed to browse the site or use the first free PDF. 達人 (Tatsujin) asks for a quick email sign-in when you actually start learning, so progress can be saved.
No. Free Resources are PDF and audio. 達人 (Tatsujin) is the interactive app with search, saved progress, pitch accent, and SRS.
No. Each core volume is a separate one-time purchase: 20 phrases are free and the remaining 300 normally cost $29. Volume 1 is the current release and has a $19 founding-member launch price; Volumes 2–5 are planned next, and more volumes or themed editions may follow.
On the same device, no. Once you've entered your email anywhere on the site, we remember it across Tatsujin and the free releases and won't ask again.
