    An all weather running track is the common term to describe a rubberized artificial running surface for the sport of track and field athletics. In this article, history, structure-property relationship, and recent progress of the surface material in the all weather running track were reviewed.
    The first all weather running track was developed in the middle of 1960’s under the trade name of “Tartan tracks”, and in 1967, it was installed in Tokyo Metropolitan Gymnasium. Though several coliseum introduced such tracks, it was turned to be clear that the durability of the surface material was not high enough against the Japanese weather. Since then new surface materials composed of mainly polyurethane has been developed. In these days, inner structure of the truck as well as surface materials were chosen to contribute to the safety and amenity for the athletes and to the new records.

    The athletic shoe is very important equipment for athlete, because they bring out the best performance and also protect their legs from injury. Therefore the athletic shoe is generally required eight functional properties; cushioning, traction, flexibility, lightweight, fitting, durability, stability and breathability. Their properties depend on structure and material design of shoes. In the half-century, their properties have been significantly improved due to developments in new material. In this paper, it is introduced the history of material development and study of new material design about running shoes.

    Rubber covered softball was developed in Japan in 1950. Similar to rubber covered baseballs, it was first invented to substitute leather covered softballs. Since then, rubber covered softballs have been widely recognized in Japanese market for its special characteristics such as durability, safety and usability.
    In this article, the history of rubber coverd softballs in Japan is first described. Then the status of the current products and the typical manufucturing process of current rubber coverd softballs are introduced. The author would like to belive the great possibility of rubber coverd softball for its low enviromental load and good durability for playing in developing countries.

    50 years have passed since the first wet suits were developed in Japan for professional divers. Since then, applications of wet suits have expanded from professional usages such as Self-Defense Forces, Japan Coast Guard to leisure purposes such as fishing, surfing and diving. As the purposes of wet suits have been diversified, materials such as sponge rubber, jersey and adhesive, and the production facilities are improved. This report reviews history, materials, production methods and future challenges of wet suits.
