The Kansai region or the best things to do in Kinki region lies in the southern-central region of Japan’s main island Honshū. The region includes the prefectures of Nara, Wakayama, Kyoto, Osaka, Hyōgo and Shiga, often also Mie, sometimes Fukui, Tokushima and Tottori. The metropolitan region of Osaka, Kobe and Kyoto (Keihanshin region) is the second-most populated in Japan after the Greater Tokyo Area.

The terms Kansai (関西), Kinki (近畿), and Kinai (畿内) have their roots during the Asuka period. When the old provinces of Japan were established, several provinces in the area around the then-capital Kyoto were collectively named Kinai and Kinki, both roughly meaning “the neighbourhood of the capital”. Kansai (literally west of the tollgate) in its original usage refers to the land west of the Osaka Tollgate (逢坂関), the border between Yamashiro Province and Ōmi Province (present-day Kyoto and Shiga prefectures). During the Kamakura period, this border was redefined to include Ōmi and Iga Provinces. It is not until the Edo period that Kansai came to acquire its current form. While the use of the terms “Kansai” and “Kinki” have changed over history, in most modern contexts the use of the two terms is interchangeable. The term “Kinai”, once synonymous with Kinki, now refers to the Kyoto-Osaka-Kobe (Keihanshin) area at the center of the Kansai region. Like all regions of Japan, the Kansai region is not an administrative unit, but rather a cultural and historical one, which emerged much later during the Heian period after the expansion of Japan saw the development of the Kantō region to the east and the need to differentiate what was previously the center of Japan in Kansai emerged.
