Menzenchin tsumohou 「門前清自摸和」, otherwise referred as menzen tsumo or even simpler tsumo 「ツモ」, is a yaku involving closed hands. If a player with a closed tenpai hand wins with a self drawn tile, this yaku is scored.
Formation
All closed hands can qualify for menzen tsumo. Declaring riichi is not required, so damaten hands can score this yaku. A hand can win even if its only yaku is menzen tsumo. No open hand may score this yaku - the instant a player calls on a discarded tile, this yaku is invalidated.
Compatibility
^ Ippatsu requires riichi to be of any use.

Menzen tsumo with toitoi is actually the yakuman, suuankou. Otherwise, this yaku is compatible with all yaku except for houtei and chankan. Neither of those two yaku can win by self-draw.
With riichi
This yaku is typically accompanied with riichi. Of course, the use of riichi is only advisable on the current state of the game: current point standing, other player riichi calls, potentially threatening hands, tile waits, and tile availability. At times, it may simply be advisable to utilize damaten, rather than putting oneself at risk.
