In which region of Japan is Mount Fuji located? Which two prefectures does it span?

Okay, regarding the location of Mount Fuji, let me explain that for you.

Mount Fuji's Location: Chubu Region, Straddling Shizuoka and Yamanashi

Simply put, Mount Fuji is located in the Chubu Region of Japan's main island of Honshu. Given its immense size, the mountain itself sits right on the border between Shizuoka Prefecture and Yamanashi Prefecture.

You could think of it as a huge landmark "shared" by two neighbors.

A More Detailed Explanation:

Region: Chubu Region
- Japan's main island, Honshu (the largest island, home to Tokyo and Osaka), is broadly divided into major regions like Kanto (where Tokyo is) and Kansai (home to Osaka and Kyoto). The "Chubu Region" sits right in between them, forming Japan's "central waist." Mount Fuji is positioned centrally within this significant area.
Straddling Two Prefectures: Shizuoka and Yamanashi
- Mount Fuji's summit lies precisely on the boundary between these two prefectures. Therefore, whether you are in Shizuoka or Yamanashi, you can climb Mount Fuji and experience its magnificent views.
- A friendly "rivalry" of sorts exists between these two prefectures about whose side offers the more "authentic" or beautiful view of Mount Fuji, which is quite interesting.

How is the view different from each side?

To help you visualize the difference:

Yamanashi Prefecture Side: Here, you'll see the iconic Mount Fuji view often featured on postcards, frequently mirrored in lakes. The famous "Fuji Five Lakes" (including Lake Kawaguchi, Lake Yamanaka, etc.) are located on this side of Yamanashi, offering classic scenery.
Shizuoka Prefecture Side: This side provides a more southerly perspective. You might see Mount Fuji from the shores of the Izu Peninsula by the sea, or witness – and photograph – the classic scene of Mount Fuji framed by a passing bullet train (the Tokaido Shinkansen) window.

So, when you plan your visit to see Mount Fuji, you can choose to explore either Shizuoka or Yamanashi depending on which iconic view you'd like to experience.
