Koji Endo studied at Footwear college in Asakusa, Tokyo while he worked with repairing shoes. After he finished the college, he went to study under Anthony Delos in France.

In 2012, he opened a Gentille which is a order-made and repair shoe store and launched own order-made shoe brand 79 Soixante-dix-neuf. However he stopped taking orders last summer in order to move abroad and to challenge something new. We will be informed if he starts taking orders again.
