Mt. Hakoneyama (箱根山)

Flow of the course

About this spot

An artificial hill 44.6 m high in the Hakoneyama area of Toyama Park. It is the surviving garden mound from the Owari Tokugawa family villa and is known as the highest point inside the Yamanote Line loop. The summit is only a few minutes of steps and slopes away, but the path enclosed by trees really does feel like a mountain, so children can enjoy a genuine sense of climbing. At the top there is a triangulation point and a marker, making it a classic spot for a commemorative photo. The splash pond sits at the foot of this hill, so you can head straight into the water after your ascent.

Tips

The service centre sometimes displays information about summit certificates, so drop by if you are interested. The steps can be slippery after rain, so watch your footing. There are many mosquitoes among the trees, so insect repellent makes the visit more comfortable. You will work up a sweat on the climb, so rehydrate before going into the water.

Best time to visit

About 25 minutes. Just the right length for walking off lunch
