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.
Hidoshi received a complaint from Sinclair when Captain Ellis Pierce came under orders to take control of B5 following the discovery of the Great Machine on Epsilon III. He told Sinclair the order came from above him, but Sinclair was adamant that President Luis Santiago gave him full authority directly. Hidoshi agreed to confirm that, but also said Sinclair may need to deal with sharing control of the station, since Santiago's attention was diverted due to the birth of the Mars Resistance crisis. Eventually, however, he was able to confirm with Santiago that Sinclair has authority.
