【Profile】

Born in Yamatokoriyama City, Nara Prefecture.

In the 2016 Japan Championships, he broke the Olympic qualifying standard in the 200m backstroke but narrowly missed qualifying for the Rio de Janeiro Olympics by 0.24 seconds, experiencing deep regret. Fueled by this regret, he continued to challenge himself and made his first appearance as a member of the Japanese national swimming team in the 200m backstroke at the 2018 Pan Pacific Swimming Championships.

Carrying that momentum, he competed in the 200m backstroke at the 2021 Tokyo Olympics, finally achieving his long-held dream of competing in the Olympics.

He is currently affiliated with Entry Co., Ltd. He is working towards winning a medal at the 2028 Los Angeles Olympics. Furthermore, drawing on his six years of experience with school refusal in elementary and junior high school, he is also active in giving lectures nationwide.

What is "BASE FOOD," the smart fully nutritious staple food?

"BASE FOOD" is a fully nutritious staple food where one meal provides a balanced intake of 1/3 of the daily required nutrients. Using carefully selected ingredients, primarily from natural sources such as whole grains, soybeans, and chia seeds, we achieve nutritional balance and deliciousness through unique technological formulations and manufacturing methods. It is a smart food that provides 33 types of nutrients required daily, including protein, dietary fiber, and 26 types of vitamins and minerals.

Since its launch in February 2017, we have expanded the series to include BASE PASTA, BASE BREAD, BASE YAKISOBA, BASE RAMEN, BASE Cookies, and BASE Pancake Mix. The cumulative sales have exceeded 300 million bags (as of March 2026), and the cumulative number of regular subscribers has surpassed 1 million (as of November 2025).

BASE FOOD Co., Ltd. Overview

We propose new staple foods that satisfy "convenience, deliciousness, and health benefits," aiming to create a society where everyone can enjoy their meals and health is a given.
