Highlight

A tunnel built as a rockfall shelter for the defunct Kumaeno Railway. Its distinctive octagonal shape feels like an entrance to another world.

Overview

Hachikaku Tunnel is a remnant of the former Kumaeno Railway located in Misato-machi, Shimo-Mashiki-gun, Kumamoto Prefecture. Built as a rockfall shelter for the railway, which was abandoned in 1964, its unique shape makes it a popular tourist spot. The tunnel consists of seven connected octagonal structures, stretching approximately 100 meters in length. Secluded in the forest, it resembles a portal to another world. The mossy interior is dimly lit and humid, creating a mystical atmosphere. The Kumaeno Railway aimed to connect Kumamoto and Nobeoka, but this goal was never realized. However, many remnants, including Hachikaku Tunnel, remain, offering a glimpse into the railway's history. When visiting Hachikaku Tunnel, take a leisurely stroll through the forest, imagining the railway in its heyday. Other remnants of the Kumaeno Railway are also located nearby and are worth exploring.
