Why am I furiten when I only discarded a different tile?

Furiten checks ALL tiles in your wait, not just the one you want. If your hand waits on both 5s and 8s and you discarded an 8s earlier, you are furiten for the whole wait — including the 5s.

Can I still win while furiten?

Yes — by tsumo (self-draw). Furiten only blocks ron, winning from discards. Furiten riichi hands often still win by drawing the tile themselves.

What is temporary furiten?

If you decline (or miss) a ron on a discard in your wait, you are furiten until your next turn — your next draw and discard. If you had declared riichi, the furiten lasts for the rest of the hand instead.

Can I declare riichi while furiten?

Yes — riichi only requires a closed tenpai hand. But since riichi locks your wait, you are committing to winning by tsumo only. It is a real (if advanced) play; beginners should reshape the hand instead.

Furiten フリテン

The most-asked-about rule in riichi, by a wide margin. One sentence covers it: if any tile that completes your hand is in your own discards, you cannot win by ron — on anything. The rest of this page makes that sentence feel fair. (Rules here follow WRC 2025; this is one of the areas where major rulesets agree.)

The basic case

Mahjong hand: 2 of characters, 3 of characters, 4 of characters — 6 of characters, 7 of characters, 8 of characters — 3 of circles, 4 of circles, 5 of circles — 8 of bamboo, 8 of bamboo — 4 of bamboo, 6 of bamboo, winning tile: 5 of bamboo — This hand waits on the 5 of bamboo (5s). If a 5s is sitting in your own discard pile, ron is off — you may only tsumo.

You discarded a tile earlier that you now need. The game's position: you told the table that tile was safe to you. Opponents were entitled to rely on it. So you may not punish a player for discarding it back — but you may still draw it yourself. Furiten never blocks tsumo.

The case that feels unfair

Your wait is 5s and 8s (a two-sided wait). An 8s is in your discards. An opponent drops the 5s — the tile you never discarded — and you still cannot ron it.

Why the 5s is blocked too

Furiten applies to the whole wait, not the tile. If any one tile of your wait is in your discards, ron is blocked on every tile of that wait. Without this, players could safely discard part of their own wait to trap opponents. The rule is what makes discards readable — and reading discards is the entire defensive game of riichi.

Three flavors of furiten

Type	Trigger	Lasts
Discard furiten	A tile of your current wait is in your own discards	While that wait stands — change the wait, clear the furiten
Temporary furiten	You decline (or miss) a ron on a tile in your wait	Until your next turn — your next draw and discard
Riichi furiten	Any ron passed up after declaring riichi	The rest of the hand. Tsumo still wins — but no ron, on any tile, ever again this hand

What to do about it

Before riichi: check your own discards against your wait — every time. If you are furiten, reshape the hand toward a clean wait before locking it.
While furiten: you can still win by tsumo — and yes, you may even declare riichi while furiten (riichi only requires closed tenpai). Since riichi locks the wait, that means committing to tsumo-only; with many winning tiles it is sometimes a deliberate, advanced play. As a beginner: reshape the hand instead.
On defense: furiten is your shield. A tile an opponent has discarded is 100% safe against that player's ron — it says nothing about the other two players, and nothing stops their tsumo. This fact, called genbutsu, is still the foundation of all riichi defense.
