Yasui Sentetsu

In this Japanese name, the surname is Yasui.

Yasui Sentetsu (安井 仙哲, 1734–1780) was a Japanese Go player, who is said to be born in either Aizu or Kawachi Province. His year of birth is unknown, but his birthname is believed to be Hara Gonhei (原 權平). He served as an apprentice to Yasui Shuntetsu Senkaku.

In 1748, he changed his birthname to his present name, and began playing castle game oshirogo (御城碁). As he was part of a famous Go house, he would play with the other Go houses in the shōgun's castle. In 1775, his mentor Yasui Shuntetsu Senkaku retired, causing him to become the sixth head of the Yasui house.

He died on September 4, 1780.
