About Sumiyoshi Coast Park (Nagabeta Kaishouro)

Hello there!
This is Maru, a writer for Sarukuma.

Today I’m taking you to Sumiyoshi-cho, Uto City, Kumamoto Prefecture, to visit
“Sumiyoshi Coast Park (Nagabeta Kaishouro)”.

This park is a popular pit stop for travelers driving toward the Amakusa region 🚙💨

Tucked just beyond Sumiyoshi Coast Park, you’ll find the famous TV-commercial filming location: Nagabeta Kaishouro!
The name is read “Naga-beta Kai-shou-ro” — a true tongue-twister even for Japanese visitors!

Spacious parking and plenty of vending machines!

There are also covered benches with shaded roofs.

Restrooms, drinking water, and hand-washing stations are all available.

Visitors were quietly enjoying the ocean view at their own pace 🌊
It’s the kind of place where you can just zone out and breathe.

Grab some snacks or a takeaway lunch and enjoy a meal here — it’s the perfect setting 😋

There’s a small sandy area where kids can hunt for seashells and explore 👦👧

You may even spot crabs and hermit crabs scuttling around 🦀

There’s even a designated photo spot for great memory shots 😍

Why You Should Visit Sumiyoshi Coast Park (Nagabeta Kaishouro)

And here it is — Nagabeta Kaishouro.

A “kaishouro” is a path that appears only when the tide goes out. This one was originally built to help local fishermen reach their boats.
The road stretches roughly 1 kilometer into the sea, lined with 24 utility poles. When the tide rises, the path vanishes underwater — leaving only the poles standing in the middle of the ocean for a truly otherworldly scene.

I happened to arrive at sunset, right around high tide 🌊

The result was a photo that looked almost like an oil painting ✨

After dark, the lamps on the utility poles light up, creating a dreamlike scene that many compare to the world of Studio Ghibli’s Spirited Away. It’s no surprise this place has gone viral as a must-see Instagram spot!

For the best view of the poles standing in the sea, time your visit for around 3 hours before or after high tide.

It’s also one of Kumamoto’s loveliest sunset spots — definitely worth a stop on your road trip!

Be sure to capture that perfect shot 📷💖
