1949

After returning home from the war in 1945, Mr. Kihachiro Onitsuka establishes ONITSUKA Shokai in Kobe in 1949. In the same year, the company is reorganized as ONITSUKA Co., Ltd. with four employees and a capitalization of 300,000 yen.

Later, the company name is changed to ASICS, an acronym for the Latin expression "Anima Sana In Corpore Sano" ("You should pray for a healthy mind in a healthy body"), a quote from the Roman satirist Juvenal. The proverb is suggested to Mr. Onitsuka by a wartime friend offering business advice, Mr. Kohei Hori, who at the time is Director of Health and Physical Education at the Hyogo Prefecture Board of Education. The words make a deep impression on Mr. Onitsuka, inspiring his dedication to making athletic shoes with the aim of nurturing healthy young people through sports.

1950's

First Basketball Shoe

First Basketball Shoe is Released

1950

A Basketball shoe is the first sports athletic shoe made by ONITSUKA Co., Ltd.

At the time, basketball shoes are thought to be the most difficult athletic shoe to manufacture, but Mr. Onitsuka feels that "if he can overcome a high hurdle at the start, he will be able to continue overcoming other hurdles as well".
Mr. Onitsuka gives prototypes of his shoes to players at one of the leading basketball powerhouses of the day, where the shoes are repeatedly tested and refined, until the first model is released in the spring of 1950.

1951

The model released in 1950 reflects gradual improvements to achieve the stopping, turning, and dashing performance required for basketball. Mr. Onitsuka has an epiphany at the sight of vinegared octopus on his dinner table, an episode that inspires the development of his suction cup Basketball shoes.

By deepening the dimples over the entire sole to resemble octopus suction cups, both starting and stopping performance are improved. The first prototype generates too much stopping power, but improvements are made based on testing by actual players.

Marathon Shoe is Released

1953

ONITSUKA Marathon TABI is released, based on the traditional indoor "tabi" footwear that is still generally worn at sports meets in Japan at the time. The Marathon Tabi is equipped with features required for marathon running, including rubber soles and uppers that feature durable material and a hanging band.

The same year, the TIGER mark MARUP shoe, designed specifically for marathon relay races, is released.
The shoe is suited to the marathon running style, which demands speed and endurance. The shoe is designed to reduce fatigue during long-distance runs. The upper is made from vinylon, a material that is three times stronger than cotton and prevents sweating in the feet, and the shoe includes a heel sponge.

After that, genuine leather MARUP for racing is released in 1958. The shoe features a lightweight rubber sponge sole with dramatically improved flexibility and shock-absorbing properties. The name MARUP stands for Marathon Up shoes. From this point forward, the MARUP series adopts a variety of advanced materials, all the way to the year 1981, when the successor SORTIE series is released.

The durable, water-resistant, lightweight material Nylon is used in shoes for the first time.

First wrestling shoe

First Wrestling Shoe is Released

1955

A completely new type of shoe, which uses nylon in the upper, is released.

The metal eyelets are not placed on the outside but rather hidden to prevent injuries during competitions. The ventilation holes in the toe area are another notable feature. In addition, the rolled design of the sole offers superior traction and slip prevention while also providing durability. This is the archetype of the modern wrestling shoe.

This wrestling shoe will go on to leave its mark around the world as one of the signature ASICS athletic shoes.

Rubber Sponge shoe

Rubber Sponge Shoe is Released

1956

It is the first shoe to adopt the synthetic rubber sponge sole material that maintains elasticity while preventing the sole from absorbing water. Compared to the rubber-soled shoes of the day, it is dramatically lighter with enhanced shock absorption.

Designed for sprinting and protection of the muscles used for jumping, this training shoe features high-quality leather over the entire surface, with a sponge material added underneath the tongue to cushion the foot along the upper. The rubber sponge, which is a lightweight material with outstanding cushioning and durability, is also adopted by the MARUP series and becomes the standard material used for most current athletic shoes. The shoe is provided to the Japanese national team.
