Wagyan Land[a] is a 1989 platform video game developed by Now Production and published for the Family Computer by Namco.

The player character, Wagyan, has the ability to temporarily stun his enemies with sound waves shaped like the noises "Wah" (ワッ) and "Gyah" (ギャー, Gyā).

Enemies cannot be destroyed with Wagyan's sound waves, but the player can stand over one while it is stunned.

There is no energy gauge in; if the player touches an enemy or falls into a trap, one life is lost.

The objective of the game is to reach the end of each action scene by making the best use of Wagyan's sound wave attacks and jumping ability.
