Saga is Kyushu's smallest prefecture but one of Japan's richest for traditional crafts, hot springs, and ancient history. Home to the 400-year porcelain traditions of Arita and Imari, the dramatic vermillion Yutoku Inari Shrine, the sprawling Yayoi-period Yoshinogari Historical Park, and the castle town of Karatsu with its famous morning squid market.
Saga has a humid subtropical climate (Köppen Cfa), similar to neighboring Kagoshima but slightly cooler and less extreme, sheltered somewhat by its inland position on the Saga Plain between the Ariake Sea and the Sefuri Mountains. Summers are hot and humid (June–September), winters are mild with only occasional frost. Rainfall peaks sharply during the tsuyu rainy season (June–mid-July), and typhoon risk runs August–October across Kyushu. Ureshino and Takeo, Saga's onsen towns, are especially pleasant in the cooler shoulder months.
