Norio OKUBO / 犬久保則雄

Norio Okubo says that he and his team, who worked for Sanritsu, were prevented from puting their real names in the credits for the Mark III game Wanted (1989), not at Sanritsu’s request but at that of Sega, the game’s producer and publisher.
Okubo, as a fan of Yōko Minamino, mixed the latter’s nickname – Nanno – with a word sounding like his first name – 海苔王 / Nori-ō, or seaweed king, resulting in the pseudonym ‘Nannorio’. (source)
