Kohji Haneda was a talented Shogi Player who was deeply respected by Shukichi Haneda, an avid fan of Kohji who claims to be his non-blood-relative. Many people had high hopes that Kohji would win all seven major Shogi Titles due to his remarkable and extraordinary skills on shogi, however, he had only won four major Shogi Titles as he was involved in a murder case that occurred years ago.
Seventeen years ago, Kohji Haneda died under mysterious circumstances while in the United States participating in a Chess Tournament, which was a game that he also enjoyed. Ai Haibara stated that Kohji could have been murdered with the enigmatic drug APTX 4869 since she remembered a person having the same name listed on APTX 4869's Victim List. When Conan Edogawa and Subaru Okiya investigated the deaths of Kohji Haneda and Amanda Hughes, also an avid fan of Kohji and a wealthy American who had both contacts of the FBI and CIA, they discovered that the Black Organization Member Rum may have been involved in the murder case due to the missing letters on Kohji's dying message could be rearranged to spell "ASACA RUM".
Kohji Haneda appears to be a man with a pale skin, indigo eyes and a spiky black hair. Furthermore, he is usually seen wearing his eyeglasses and Kimono.
