Reading Opponents' Discards (Kawa Reading) for Beginners
Sep 23, 2026 · 6 min read
Kawa ("river") is the term for a player's row of discarded tiles. Reading an opponent's kawa is one of the most valuable skills for judging how close they are to winning and what yaku they're chasing.
Common Patterns to Spot
- Discarding terminals/honors early, then stopping -- a common sign of an ordinary hand efficiently pushing for speed.
- Suddenly discarding tiles from one specific suit mid-game -- possibly chasing Honitsu/Chinitsu in a different suit.
- Discards become more "random" or less patterned right before a riichi -- often signals a hand nearing tenpai and starting to discard tiles it had been holding for options.
- Discard speed suddenly slows down -- could mean they're weighing whether to fold or considering risk before discarding.
Kawa After Riichi
Once an opponent riichis, EVERY tile they discard afterward is automatically safe for anyone to discard too (since they must discard exactly whatever they draw, with no choice) -- except the exact tile they're waiting on, which would mean they're furiten on it.
Kawa reading takes gradual practice -- start by watching for 1-2 simple patterns (like when an opponent stops discarding edge tiles) before trying to read everything at once.
Combine this skill with safe folding strategy.
