Osaka Miyakojima Technical High School
Vintage Japan Zett Koshien Osaka Miyakojima Technical High School Baseball Jersey
KOSH-025
Miyakojima Technical High School, located in Osaka, first drew national attention with its impressive debut in the 1951 Summer Koshien Tournament. That year, the team dominated the Osaka regional qualifiers—defeating Yuhigaoka, Shimizudani, Kishiwada, Yao, and Naniwa Commercial—to win the championship and earn their first Koshien appearance.
On the big stage, they upset Waseda Jitsugyo of Tokyo in the opening round, came from behind to beat Toyohashi Commercial from Aichi in the second, and pushed Kyoto’s powerhouse Heian High into a thrilling 10-inning game before falling in the quarterfinals—finishing their run with a solid 2–1 record and a spot in the top 8 nationally.
In Japan, Kōshien refers to the two annual baseball tournaments played by high schools nationwide, culminating in a showdown at Hanshin Kōshien Stadium in Nishinomiya, Japan.
The tournaments have become national traditions, and many frantic students and parents travel from their hometowns to cheer for their local team. It is common to see players walking off the field in tears after being eliminated from the tournament by a loss. The star players of the championship team will achieve a degree of celebrity status.
