This article will convey all the charms of Tenranzan Mountain and provide thorough explanations of climbing courses, access methods, nearby tourist spots, and seasonal highlights.
What is Tenranzan Mountain? Basic Information and Characteristics
Tenranzan Mountain is located in Hanno City, Saitama Prefecture, at an elevation of 197 meters (some summit signs indicate 195 meters). Although the elevation is low, the views from the summit are excellent, offering a panoramic view of Hanno City, and on clear days, you can see Mount Fuji, Tokyo Skytree, and the mountains of the Oku-Musashi and Okutama regions.
History and Origin of the Name of Tenranzan Mountain
Tenranzan Mountain has a storied history with changing names over time.
Atago Mountain Era
Originally, it was called “Atago Mountain” because Atago Gongen was enshrined at Nenin Temple at the base of the mountain.
Rakan Mountain Era
During the Edo period, as an expression of gratitude for the recovery from illness of the 5th Shogun Tokugawa Tsunayoshi, his mother Keishoin donated sixteen stone statues of Rakan (Arhat), and the mountain became known as “Rakan Mountain.” These sixteen Rakan statues remain on the mid-slope to this day and are one of the important highlights.
Change to Tenranzan Mountain
On April 18, 1883 (Meiji 16), Emperor Meiji observed from the summit of this mountain the spring exercises of the Imperial Guards held at the base of the mountain (tenshin/imperial inspection), which led to the name “Tenranzan Mountain.” A monument commemorating this imperial visit is built on the summit, preserving this historical event for posterity.
As a result of this history, Tenranzan Mountain was designated as the first nationally designated scenic spot in Saitama Prefecture and is known as a mountain of high historical and cultural value.
Geographic Features of Tenranzan Mountain
While resembling a hill more than a mountain, Tenranzan Mountain is positioned as the starting point of the Oku-Musashi Nature Trail. To its west lies Tono-Suyama Mountain, and hiking courses combining both mountains are popular.
The greatest appeal is the ease of access: approximately 20 minutes on foot from Hanno Station to the trailhead, about 5 minutes on foot from the “Tenranzan-shita” bus stop if using the bus, and about 20 minutes from there to the summit.
