Basketball Day (Basuketto Bōru no Hi)

What Is Basketball Day?

December 21st is "Basketball Day." It commemorates December 21, 1891, when Canadian-born physical education teacher James Naismith held the world's first game of basketball at the YMCA training school in Springfield, Massachusetts. Naismith's original rules numbered just 13, and the game was simple: throw a ball into a peach basket nailed to the wall.

The Story Behind Basketball's Invention

Naismith was asked to invent, in just 14 days, a game that students could play safely indoors during winter. The result was basketball—a sport that avoided heavy physical contact while rewarding teamwork, agility, and precision. Famously, the peach baskets used as goals had no holes in the bottom, so someone had to climb a ladder to retrieve the ball every time a point was scored.
