Hajime Sugoroku (Tomokazu Seki) is the artist credit used by 関 智一, a Japanese voice actor and performer born on September 8, 1972, in Kōtō, Japan. The credit is closely tied to his anime-facing work, making it useful for listeners searching for Tomokazu Seki's voice roles, seiyuu appearances, and other projects connected to Japanese animation culture.
In 2026, Seki stayed visible across anime-related media: he appeared as a Friday MC on Seiyuu to Yoru Asobi, was announced as a guest voice cast member for the theatrical Keroro Gunso film, and took part in the July 3, 2026 Fushigi Yuugi Blu-ray Box release event alongside Hikaru Midorikawa. Those appearances reinforce his long-running presence in anime circles and help place the Hajime Sugoroku credit within his broader career as both a performer and a recognizable voice in Japanese animation.
