Hidoshi was an Earth Alliance Senator and in 2258 he served as Jeffrey Sinclair's primary liaison to EarthGov, on behalf of the Babylon 5 Senate Oversight and Appropriations Committee. [1]

Hidoshi's grandfather once worked on the Spacedock on New Kobe and so had great sympathy for workers' rights in labour disputes. When an illegal strike broke out among the Dockers' Guild Babylon 5 in 2258, he instructed Commander Jeffrey Sinclair to end the strike quickly. Sinclair's ultimate solution both amused and impressed Hidoshi.[2]

By mid-2259 he was no longer an Earth Senator having either retired or voted out of office, though he was still quoted in the news. [3]
