With no formal art training, Tenjin has staked his claim as one of the premier illustrators in Japan, having drafted mechanical art for the Macross, Gundam, and Space Battleship Yamato franchises. This artwork includes model box covers, DVD covers, art books, and mechanical designs for some of the later shows.
Tenjin began drawing Macross' signature fighter, the VF-1 Valkyrie, while he was still in college for a personal fansite. His love extended to doing pinups for the Macross Chronicle, a weekly fan publication, which eventually led to doing work for another fan publication, the Space Battleship Yamato Fact File. Since then, Tenjin has illustrated the box art for several Gundam Master Grade model kits for Bandai and the cover for the PlayStation 2 game Gradius V.
Tenjin's earlier works also led to him to become the main visual artist or special effects artist for numerous anime including Macross Zero, Macross Frontier, Hellsing Ultimate, Gundam Evolve, the Saint Seiya movie, and Genesis of Aquarion. This year, Tenjin can be found as the cover artist of the Japanese version of Sony's Starhawk and as the mecha artist of the TV series, DVD/BD packaging covers and promotional artwork for Aquarion EVOL.
