What is Tatami?
The complete home for your judo club's grading syllabus.

From an empty mat to a club studying the right syllabus — without spreadsheets or scattered video links.

Questions, answered
Everything you need to know to get your club started.
How do my judoka join?
Share a single join code. They sign up, enter the code, and instantly see your club's syllabus — then start studying and tracking their progress.
Can I use my own club's syllabus?
Yes. Start from a governing-body template (BJA Mon, BJC junior/senior, USJF or the Kodokan Gokyo) or build your own grades from scratch, then curate every belt with your videos, coaching points, terminology and kata.
Does every technique come with a video?
Yes — techniques include official Kodokan / IJF demonstrations out of the box, and you can swap in your own clip on any requirement.
Does it work on phones?
It fully works on mobile.
Is my club's data private?
Every club is completely separate. Your syllabus, teacher's notes and members are only ever visible to your own club.
