What is "johanan"

Johanan ( Hebrew Yôḥānān), son of Joiada, was the fifth high priest after the rebuilding of the temple in Jerusalem by the Jews who had returned from the Babylonian captivity. His reign is estimated to have been from c. 410–371 BCE; he was succeeded by his son Jaddua. The Bible gives no details about his life. Johanan lived during the reigns of king Darius II of Persia and his son Artaxerxes II, whose empire included Judah as a province.
