History
The name Bibai is derived from Ainu word "pipa o i", meaning "Place (swamp) with many cockscomb pearl mussels".[1][2]
- 1890 - The village of Numakai was founded.
- 1925 - Numakai village became Numakai town.
- 1926 - Numakai was renamed Bibai.
- 1950 - Bibai town became Bibai city.
- 1982 - Bibai Dam was completed.
At its peak, Bibai was a coal town that produced over a million tons annually. However, ever since the mine was closed in 1972, the city has suffered a slowly declining population.[3]
Geography
