Reviews Summary

Visitors praise Oyashirazu Coast for its unique combination of a historic brick tunnel, a beautiful secluded beach accessed by steep stairs, and dramatic cliffside scenery. The hike is considered rewarding, offering a memorable outdoor experience. Some caution is advised regarding the physical demands of the trail and potential wildlife encounters.

"This is a great outdoor experience combining forest, sea and an abandoned tunnel. Park at Oyashirazu Kanku or in the car park on opposite side of the road. You can do the loop in clockwise or counter-clockwise direction, but both are equally demanding physically. The tunnel is 670m long and refreshingly cool. Take 120 steps down to the small beach. If you have good physical fitness, the scenery and serenity make this a must-do when in the Igoitawa area."

Matt Raschke

"beautiful place but be prepared to walk a lot. To access the beach you have to go down stairs but it’s beautiful. I walked the dark tunnel, i recommend"

Diana Noureddine

"Careful if you walk here!
I saw a black bear on Wednesday, November 12, 2025, at around 4:00 p.m., just near the road. It was right after the sign that says “300 metres to Rock Bridge – 300 metres to parking lot”, on the seaside, only a few metres from the road."
