Shigeru Ohmori (/ˈʃɪɡɛruː ˈoʊmoʊrɪ/ SHI-ger-roo OH-moh-ri; Japanese: 大森滋, Hepburn: Ōmori Shigeru, IPA: [oːmori ɕigeru]; born 29 February 1980) is a Japanese video game director, designer, and developer best known for his work in the Pokémon franchise.

[2] According to Ohmori, his parents died when he was young, which served as inspiration for the character Arven in Pokémon Scarlet and Violet.

[3] He went to a vocational school and studied programming, and before he had graduated he had worked on the commercial video game title Yakiniku Bugyou.

According to Ohmori, due to the Nintendo Switch's increased resolution, it became possible to include smaller visual items along with larger ones, enabling the addition of features such as multiplayer cooperative battles.

One design item which took up Ohmori's attention was the grass in the games – as players perceived grass patches to be potential location for Pokémon, it was considered a core design element and Ohmori took half a year with his team to finalize it.
