The hand needs at least one terminal and at least one honor. Only 1s and 9s is chinroutou. Only honors is tsuuiisou. Both are .

Open or closed
Tenhou's rules list honroutou at 2 han and don't mark it as losing a han after a call. The EMA 2016 rules file it with the 2 fan yaku and say to add two fan for all pungs or seven pairs.

The World Riichi Championship rules add that honroutou doesn't combine with chanta. needs a run, and this hand has none.
Common mistakes
- Pricing it at 2 han. Toitoi or seven pairs always comes with it.
- Scoring chanta as well. Honroutou has no runs, and chanta needs one.
- Calling an all-terminal hand honroutou. With no honors, it's chinroutou.
- Adding fu to the seven-pairs version. Chiitoitsu stays at 25.
