Generation
Samurai start each game with a +0 yumi and a stack of ya to use as ammo.[1]

Description
Samurai get +1 to-hit, multishot and damage bonuses when firing ya from a yumi.[2][3][4] For other roles, it is essentially the same as a normal bow.

Strategy
The yumi provides a more-than-decent ranged option for Samurai in the early game.

History
The yumi is introduced in NetHack 3.1.0; in previous versions, Samurai instead started with a stack of shuriken.[5]

Origin

Wikipedia has an article about:
Yumi

As used in English, yumi refers more specifically to traditional Japanese asymmetrical bows, which includes the longer daikyū and the shorter hankyū used in the practice of kyūdō and kyūjutsu, or Japanese archery.
The yumi was an important weapon of the samurai warrior during the feudal period of Japan, with ya as ammo, and their designed evolved from maruki yumi that date back to pre-3rd century CE: these were constructed with small saplings or tree limbs, and came in various sizes, with the majority of them being short with a centre grip. The first written record of the asymmetrical yumi appears in the Book of Wei, a Chinese historical manuscript dating  bacl to the 3rd century CE—the oldest one found to date was discovered in Nara Prefecture and estimated to be from the 5th century. The yumi underwent a change in length and construction method during the the Heian period (794–1185), then again to a two-piece bamboo-and-wood laminated yumi by the end of the 10th century—its construction evolved over the next several hundred years, and settled into its modern design by the 16th century.

Variants
dNetHack
In dNetHack, Samurai receive the Yoichi no Yumi, a lawful artifact yumi, as their crowning gift. It grants +1d20 to-hit and double damage to ya fired from it, and can be invoked to create more ya similar to the Longbow of Diana.

SlashTHEM
SlashTHEM adds the Yoichi no Yumi from dNetHack as one of the many new artifacts - it has the same traits as in dNetHack, but lacks any particular connection to Samurai. Yoichi no Yumi can be created by Duri at The Forge.

Encyclopedia entry

The samurai is highly trained with a special type of bow,
the yumi.  Like the ya, the yumi is made of bamboo.  With
the yumi-ya, the bow and arrow, the samurai is an extremely
accurate and deadly warrior.
