Very good
5 ReviewsReviewers appreciate the tunnel's historical significance and unique architecture, especially its beautiful arches. The main drawback is that it's no longer accessible for passage, though it was briefly opened in January 2024 for a special event.
Fun facts
The tunnel was constructed to protect against frequent rockfalls from Yusaka Mountain, which caused numerous accidents in the early Showa period.
It was officially designated a national important cultural property in 2015.
The tunnel was closed in 2014 after a bypass was completed, partly due to a collapse in 2005 and its narrow width causing traffic jams for large buses.
