Seiji Tsutsumi

was a Japanese businessperson, author and poet, also known by the pen names and .

Background Tsutsumi was the son of Yasujirō Tsutsumi, founder of the Seibu Railway company and a long-serving member, and eventually speaker, of Japan's House of Representatives.

He was born in Tokyo in 1927. During his childhood, he lived with his mother Misao and half-sister Kuniko. Misao wrote traditional Japanese poetry, which was Tsutsumi's initial introduction to writing. He later took up the practice himself, writing waka by his teen years; however, he would not publish any of his work until his late 20s. He resigned as head of Saison in 1991 following the collapse of the Japanese asset price bubble, but continued as head of the Saison Cultural Foundation, which he founded in 1987.

Just before the death of his father Yasujiro, his brother Yoshiaki Tsutsumi was nominated as his heir, potentially due to Seiji's brief involvement with the Japanese Communist Party after the Second World War.

In addition to his business career, he has also had a notable career as writer and poet under his pen name Takashi Tsujii, and served as Director of International PEN Club, Japan.
