Mt. Hanabusayama – A Hidden Historic Highland in Shinagawa
Mt. Hanabusa (or Hanabusayama) (花房山), nestled in the Kami-Ōsaki area of Shinagawa Ward, is a historically rich and geographically striking corner of Tokyo. Though modest in height, it is considered one of the legendary Jōnan Gozan (城南五山) — the “Five Great Hills of Southern Edo.” These five elevations were prized during the Edo period for their scenic beauty and strategic positioning, often housing the estates of daimyo and high-ranking officials.
Hanabusayama, which literally translates to “flower cluster mountain,” wasn’t named for the profusion of blossoms that once graced its slopes. Instead, It originates from the fact that Viscount Hanabusa Yoshimoto (花房 義質) built his mansion here during the Meiji period. However, the name becomes especially poignant during sakura season. Each spring, the streets surrounding the JR Yamanote Line near Gotanda are lined in a delicate wash of pink, visible even from train windows — a fleeting but memorable sight that has earned it its place in the Shinagawa Hyakkei (100 Views of Shinagawa).
🌸 The Sakura Promenade on Mt. Hanabusa
The cherry tree-lined avenue sits on the edge of the hill, forming a tranquil border between residential districts and rail lines. Although quiet for most of the year, the path comes alive in late March and early April when the blossoms burst open, drawing photographers, trainspotters, and neighbourhood residents alike. Because it is slightly elevated and protected from commercial overdevelopment, the canopy creates a charming tunnel effect that is especially magical at dusk.
🏯 Jōnan Gozan and the Prestige of Elevation
The Jōnan Gozan (城南五山) — translated as “Five Hills South of the Castle (Edo Castle)” — included:
- Hanabusayama (花房山)
- Ikedayama (池田山)
- Goten’yama (御殿山)
- Yatsuyama (八ツ山)
- Takanawa (高輪)
These hills were prestigious locations during the Edo period and into the Meiji era, often home to the estates of feudal lords, court nobles, and foreign dignitaries. Hanabusayama was no exception. It offered proximity to central Edo, views of the bay, and symbolic elevation — both physically and socially.
🏡 Former Estates and Quiet Affluence
While Mt. Hanabusa itself did not host a palace like nearby Gotenyama, it was surrounded by mansions of high status during the Meiji and Taisho periods. Today, the area retains its exclusivity, marked by embassies, old consulates, and the sprawling Seisen University campus (formerly the Shimazu Duke’s Residence) just down the hill. This adds to the quiet, elevated character of the district.
🚉 Access and Modern Life
Mt. Hanabusa lies between JR Gotanda and Meguro Stations, directly bordering the JR Yamanote Line. It is not a park per se, but a residential hillscape — crisscrossed by sloped lanes and sakura-lined streets that maintain their air of old Tokyo refinement. While the area is largely private, the public can enjoy views from nearby paths and roads. Even the trains become part of the view, offering a moving frame for the blossoms each spring.
