A subscription site for Kenta Iwamoto's grappling instructionals. It centers on no-gi grappling, the kind you see at ADCC: mostly the techniques he teaches in class, plus sparring and match breakdowns.
Over 600 videos, about 60 hours (as of October 2026). Roughly: 440 technique lessons from class, 60 breakdowns of matches and sparring, 45 talks on how to train and think, 30 sparring rounds, and 25 seminar and mini-series videos. The average video is 6 minutes and two in three are under 5, just right for checking one technique before training. There are also 39 longer videos over 15 minutes, up to 71.
Counting what's in the library (as of October 2026), it suits you if you:
· train no-gi grappling (ADCC rules and similar). Under 1 in 10 videos mention the gi
· want depth on finishing. 160 videos on submission offense, with 55 on heel hooks and 42 on ankle locks
· want to sharpen how you start from standing. About 150 standing videos
· like to check one technique quickly before or after training. A-B repeat, speed control and mirror let you loop it
· want to learn in English. Japanese and English subtitles, plus English dubs
Standing is deep, about 150 videos, with wrestling and Greco elements. On the ground, leg locks (55 heel hook, 42 ankle lock) and back and turtle (over 100 each) lead. Outside ashi, K guard and 50/50 are the most common guards; smash pass, split squat and north-south the most common passes (as of October 2026).
Every video is tagged along eight axes: category (class, commentary, sparring and so on), situation (submission offense and defense, standing, guard passing and more), phase of engagement, and competition (ADCC, AIGA and others). Then by technique: 17 submissions, 5 pins (back, turtle, mount and more), 17 guard passes and 26 guards. In the library you narrow down with these tags and search.
Over the past year, about 28 videos a month (6 to 7 a week). When Kenta posts a new video, a twice-daily automatic check brings it into this site, with Japanese and English subtitles and tags added automatically. The site itself improves almost every week too; see What's new below.

Same price, same videos. If Patreon is easier for you, watch there. What I built here are tools for learning: search by position, technique and competition, Japanese and English subtitles, English dubs, A-B repeat, mirror mode, speed control, timestamped notes, your own playlists, and an Android app that saves videos to your phone. If that difference appeals to you, join here.
