[1] Chiba Prefecture Shisui has a humid subtropical climate (Köppen Cfa) characterized by warm summers and cool winters with light to no snowfall.

The area around Shisui has been inhabited since at least the Japanese Paleolithic, and archaeologists have found stone tools and the foundations of houses dating 24,000 years ago.

After the Meiji Restoration, Shisui Town was founded on April 1, 1889 within Inba District of Chiba Prefecture with the creation of the modern municipalities system.

In terms of national politics, the town is part of Chiba 13th district of the lower house of the Diet of Japan.

The central part of the town was developed as a regional commercial center beginning in 1975 due to the construction and expansion of the airport.
