Hashida Kantarou was the only son of Hashida Kahei, and the one in line to inherit the Hashida company. However, he would soon die from an illness, leaving his son, Hashida Kanshichirou, the only living heir.
Kantarou had a strikingly similar appearance to that of Sakata Gintoki of the Yorozuya, causing great confusion as to who was the real father of Kanshichirou. However, this would all be solved when Ofusa came clean and told everybody the truth later on.
Even though he was ill and had to stay in bed most of the time, he enjoyed playing pranks on his housekeepers, even going as far as pretending to die.
