Mount Hongū

Mount Hongū reaches 789 meters at the border where Toyokawa, Okazaki, and Shinshiro meet in Aichi Prefecture. The wooded slopes contain established hiking trails that lead to the summit and viewpoints overlooking the surrounding region.

The mountain has marked a natural boundary between administrative regions since ancient times, shaping how the land was organized. This geographical division has persisted through centuries and remains relevant to the region's boundaries today.

Shinto shrines on the mountain host ceremonies where local people honor the spiritual connection between the land and nature. These practices remain an important part of community life in the surrounding areas.

Trails are open year-round with parking at the base and rest areas along main routes. Wear sturdy hiking shoes and bring water, especially if spending several hours on the mountain.

From the summit, visitors see a broad view of Aichi's landscape ranging from urban areas to natural formations. This vantage point reveals how the three administrative regions differ geographically in one expansive view.
