Baseball in Japan has a long, rich history. Consequently, badges for the sport are
plentiful, most of them being tournament or school club badges. It is of use to note,
however, that there is also a 'soft baseball' sport often played at schools. The kanji to
identify this sport are 軟式 (
nanshiki), which preface the phrase for baseball: 野球 (yakyū).
The difference is singular: the ball in baseball is made of cork while the ball in soft
baseball is made of rubber. The rules are the same (as far as I know).

Soft baseball began in Japan in 1919, in order to give younger children a safer game to
play. After its introduction, participation in the sport allegedly skyrocketed.

Here is a portion of the Wikipedia article about the history of baseball in Japan:

"Baseball is one of the most popular sports in Japan. It was introduced to Japan in 1872
by Horace Wilson, who was an English professor at the Kaisei School in Tokyo. The first
baseball team was called the Shimbashi Athletic Club and was established in 1878."
