Appears chubby and often seen wearing a suit and tie. He has dark brown hair that is quite shaggy and his bangs reach his eyebrows.
He loves to give people his autograph and he has an extremely positive attitude which is seen when giving people his autographs he likes to write "eventually" or "going-to-be" in a happy manner. This is also seen when he rejected playing with Hikaru, though he later agrees when Hikaru tempts him by telling him he wants his autograph if he wins him. This is also seen as although he recognized and knows the strength of the newer generations of Go players, he did not feel depressed or anything negative. This could mean that he is very encouraging towards them and makes him feel that way as well.
He seems to be the kind of person who loves helping others as well, this has been seen a few times. The most obvious part is when he helped Hikaru to bring down fake goods and even trusted him when he told him that an important historical significant Go board is a fake.
