Beautiful spot accessible with Short hills along the beach from the coast road to the North. However parking is a challenge (currently closed) at the road access so I recommend going one tunnel to the north and parking land-side there. There’s a pavement back through the tunnel.

Not worth stopping to this spot

Passed by while driving, parked in the parking lot, and went down a bit toward the shore. There are stairs, and when you come out of the tunnel, the sea spreads out before you. The sea breeze and the sound of the waves are soothing. The footing is pretty bad so I couldn't go any further, but there was someone crossing by canoe. The rocky area around here is breathtaking. It was a shame that lots of trash from overseas had washed up and was piling up.

As I thought... is it a typo? After about an hour of walking over gravel and rock surfaces in motorcycle off-road boots that weren't designed for walking at all, at the shore I arrived at, I unfortunately couldn't hear the sound of rocks knocking against each other in the waves. And on the hut were the words "Sacred Site Sai no Kawara." Right? I thought the "Sai no Kawara" written with the character for "west" must surely be a typo, but then the tunnel on National Route 229 says "Sai no Kawara Tunnel" with the "west" character. What on earth is going on? I didn't meet a single person, I drank all my water in the scorching heat, walked so much the sole of my SIDI off-road boots nearly came off, slid down rocks on my butt and tore a hole in my pants... and after going through all that to get here, I just can't accept it. This is the rating from me, someone who almost never gives 3 stars to spots like this (almost always 5 stars). What is this place, anyway? However, I didn't end up saying hello to a brown bear that came to the shore to eat salmon, and I made it back safely to my bike parked on the national road, so the sense of accomplishment at that moment was outstanding. Refer to the photos for the route to the site. Oh yeah... as others mention in their comments too, the footing is wobbly so it's hard to take your eyes off it, and I learned for the first time how painful it is to keep looking down the whole time you walk. I've climbed mountains in motorcycle off-road boots before, but this was harder.

On my first visit I gave up due to the rough path and sunset; this time I prepared properly and finally managed to visit. There used to be a walking trail, apparently, but it's been abandoned and can't be used. The way to get there is to walk along the shore from the Sai no Kawara parking lot on National Route 229. The first part is walking along a beach strewn with loose rocks about 20cm in diameter, and the latter part involves climbing up and down rocky areas. Walking near the boundary between the beach and the slope is relatively easy going, but you can't completely avoid loose rocks, and there are places where the slope is actively collapsing, so walk while carefully checking your footing ahead. I recommend hard-soled shoes that protect up to the ankle. Also, mamushi vipers apparently live here, so be careful around grass and in the shadows of rocks. Be fully prepared against brown bears too.
