Kushimoto, the southernmost town on Japan’s main island of Honshu in Wakayama Prefecture. Here, you’ll find a breathtaking view that will leave you speechless the moment you set foot on the shore.
This is “Hashigui-iwa Rocks,” a nationally designated Place of Scenic Beauty and Natural Monument.
A series of giant rocks stretching regularly across the sea for about 850 meters. Is it the artistry of nature, or a divine miracle? In this article, we’ll cover everything you need to know to enjoy this location to the fullest.
The Origins of Hashigui-iwa: Where Legend and Science Meet
Hashigui-iwa has “two faces” that make the scenery look entirely different once you know its background.
The Bet Between Kobo Daishi and Amanojaku
According to legend, the great priest Kobo Daishi (Kukai) once made a bet with a mischievous spirit called Amanojaku to see if they could build a bridge to the offshore island in a single night.
Panicking as the priest erected rocks with incredible speed, Amanojaku mimicked the crowing of a rooster to trick him into thinking dawn had arrived. Kobo Daishi gave up the work and left.
It is said that the “bridge piers” remaining from that night are the rocks we see today.
Geology Reveals a “15-Million-Year Mystery”
From a scientific perspective, the rocks were formed by volcanic activity approximately 15 million years ago. Magma intruded into layers of mudstone, cooling and hardening into a wall of “Quartz Porphyry.”
Over eons, the surrounding softer earth was eroded by the waves, leaving only the hard sections standing like pillars. It is a globally rare geological dyke.
When is the Best Time for Sightseeing and Photography?
Hashigui-iwa shows completely different expressions depending on the time of day and the tide.
A Sunrise Selected Among “Japan’s Top 100”
This is a sacred site for photography enthusiasts. The sun rising between the rocks can only be described as divine.
The “magic hour,” when the sky shifts from orange to purple, makes for a perfect shot through any lens.
Exploring the Rocks at Low Tide
When the tide is out, you can walk right up to the base of the rocks. Looking up at them from close range, they feel far more massive and overwhelming than they do from the observatory.
The tide pools are full of small creatures like crabs and fish. It’s the perfect spot to enjoy a “nature observation session” with your children.
Illumination: A Mystical Night Display
For a few days every autumn (usually late October to early November), Hashigui-iwa is bathed in light. Light Production

The colors may change daily. The vivid rock pillars rising out of the pitch-black Pacific Ocean offer a mystical atmosphere 180 degrees different from the daytime. Photography Tip

Aim for the “reflection” on the water’s surface. On a calm day with little wind, you can capture a beautiful mirror-like shot.
