Seiji Tsutsumi

Seiji Tsutsumi (堤 清二) was a Japanese businessperson, author and poet, also known by the pen names Takashi Tsujii (辻井 喬) and Ikuo Yokose (横瀬 郁夫).

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.

After receiving his degree in economics from the University of Tokyo in 1951, he re-enrolled as a literature student and worked as a secretary to his father.

He joined the Seibu Department Stores in 1954.

The two married in 1955 and had a son, Kōji; however, the pair divorced around 1964.

Following the death of his father in 1964, he led the spin-off of its logistics business to form the Saison Group, which eventually included the Seibu department stores, Seiyu supermarkets, Wave (a music shop), Parco (shopping complex), and the Muji and Loft variety store chains.

He later wed Asako Mizuno in Paris in 1968.

Mizuno later gave birth to Tsutsumi's second son, Takao.

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 Tasujiro, his brother Yoshiaki Tsutsumi was nominated as his heir, potentially due to Seiji's brief involvement with the Japanese Communist Party after the World War Two.

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.

His work has been translated into Arabic, Chinese, English, French, Korean, and Russian.

Tsutsumi once described his writing career as an equalizer to his business ventures, and vice versa: "I find that I can get rid of the business stress by writing. And I can avoid getting consumed by writing problems by being preoccupied with business."

While working as a political secretary to his father, Tsutsumi met Motoko Yamaguchi.

Tsutsumi died of liver failure in Tokyo on November 25, 2013.
