In 1934, Japan's first professional Baseball team, the Dai Nippon Tokyo Baseball Club (now the Giants), was founded.

Soon after, there was a growing movement to build a new Baseball stadium in Tokyo city and to have a baseball team attached to the stadium, and Korakuen Stadium was born.

The opening ceremony for the new and highly anticipated stadium was held on September 11, 1937. Following that, the Red and White All-Star game was held at 1:55 pm, during which Shigeru Mizuhara of the Giants hit the first home run Korakuen Stadium.

Until then, Jingu Stadium had been a popular mecca for the Tokyo Rokugaku Baseball, but Korakuen Stadium later became the home of the professional Baseball Giants, and from 1938, the 12th National Inter-City Baseball Tournament was held for the first time in Korakuen, and from then until now, the Inter-City Baseball Tournament held in Korakuen has had a "summery" Since then, the National Inter-City Tournament held at Korakuen has come to have a significance as a "summer tradition.

Needless to say, even before the war, star players of the Giants showed off their beautiful skills at Korakuen. The name Sawamura Eiji is still famous today. The players who joined the team in 1938 were called the "Flower Class of 13," and included players who made their mark in Japanese Baseball history, such as Kawakami Tetsuharu and Chiba Shigeru. In the same year, Nakajima Haruyasu achieved the first triple crown in Japanese professional Baseball.

Japanese professional Baseball was still in its infancy, but it was also growing in popularity, and Korakuen Stadium was filled to capacity for the first time on February 26, 1939, for a game against the Giants.

However, as the years went by, Japan became more and more war-like, and players were sent to the battlefield. Then, in the fall of 19, the Japanese Baseball Patriotic Association announced a temporary suspension of professional Baseball, and Korakuen Stadium went into "hibernation."

The stadium itself became an anti-aircraft gun post, and the grounds were transformed into a vegetable garden. No one knew the fate of Korakuen Stadium at the time.
