Coaching, reviews & mahjong localization.
I work with players who want stronger table decisions, and with overseas teams that need accurate Japanese mahjong language, content and process help.
Three kinds of tables
Players
Stuck between ranks, leaking points in the mid-game, or preparing for serious online or offline play.
Coaching & game reviewsClubs & leagues
English-facing events, teaching materials, or rule and localization questions that need a Japan-pro eye.
Consulting & contentPublishers, apps & media
JP⇄EN copy that doesn’t sound like a dictionary: yaku, UI, articles, scripts.
Translation & writing

A sample review
Every review is a written breakdown of your key decisions, with a scorecard and the pattern that costs you the most.
Review · Tenhou 鳳凰卓 · South
- Turn 9 · Key decisionYou cut 9s. The 4s draw completed 3-4-5s, so 8m is the only tile that connects to nothing. Cut 8m: tenpai on 8s.
- Turn 12 · Push or foldDealer riichi on turn 11. With a cheap kanchan and 2 safe tiles, this is a fold spot. You pushed 5p and dealt in.
- Pattern across the gameThree times you kept a lone honor over a connected tile. Cut them earlier and your hand stays one step faster.
Scorecard
- Tile efficiency7/10
- Defense5/10
- Hand value6/10
- Placement play4/10
Your homework
- Cut isolated honors before turn 6
- Fold cheap hands against dealer riichi
- Replay this game with the notes open
