Debtor and one-time coworker of Kaiji. One year before the first tournament on Espoir, he lured Kaiji into cosigning a loan for him, making Kaiji liable in case Furuhata did not repay the loan. Although believed to have disappeared, Kaiji discovers him on Espoir and makes an alliance with him after Funai's betrayal. Furuhata is the sharper of Kaiji's allies, and is able to follow and quickly adapt to Kaiji's strategies. He is also more honest and loyal than any would have believed. However, Furuhata also betrays Kaiji and attempts to use his funds to escape the ship.
