While dredging through 50 years of games in my pursuit of estimating park effects, I discovered a few things by accident, which provided a few reminders of how much things have changed over the years.

The first thing that caught my eye was how makeshift the schedules with so few usable ballparks.

In 1950, Tokyo’s Korakuen Stadium was the main home park of the Central League’s Yomiuri Giants, Taiyo Whales and Kokutetsu Swallows as well as the Pacific League’s Tokyu Flyers, Daiei Stars and Mainichi Orions. Osaka’s Namba Stadium was kind of home to the Nankai Hawks and Kintetsu Pearls and the CL’s Shochiku Robins.
