Shiraoi (白老町, Shiraoi-chō) is a town located in Iburi, Hokkaido, Japan.

According to the town's official website, the name, Shiraoi, means Rainbows in the Ainu language.

Two significant events occurred during this expansion: in 1874, Mount Tarumae erupted, and in 1881, the Emperor Meiji visited.

[1] Shiraoi is crossed by a number of rivers running from the mountains like Mount Horohoro to the Pacific Ocean.

These include: Mount Horohoro and Lake Kuttara are part of Shikotsu-Tōya National Park.

Wind velocity averages merely 1.6 metres per second (3.6 mph), that is less than half of the neighboring Tomakomai and Muroran.

In the 1930s, Shiraoi began the cultivation of mushrooms,[8] such as Shiitake, and mullet roe (or karasumi) at Kojohama.

Shadai Stallion Station has bought high-profile thoroughbreds for their breeding program, such as Kentucky Derby winner War Emblem.
