Shomyo Falls — Why You Need to Go Now

This isn’t just a waterfall. This is Japan’s tallest waterfall — a 350-meter freefall of snowmelt and mountain water that crashes into a mist-filled gorge. It’s located deep in the Chubu Sangaku National Park, right at the edge of the Tateyama mountain range. And yet, somehow, almost nobody talks about it.

That’s a mistake. Because missing this… It’s like skipping the Grand Canyon when you’re already standing in Arizona. Well, maybe not that important, but it’s nice.

I’m William, the Barefoot Surfer. I’ve been living in Toyama for a few years now. It’s not that well known for tourists, even amongst the Japanese.

Toyama makes a perfect stop between Tokyo and Kyoto. A countryside area known for some of the best seafood, and some great nature having both the famous Tateyama mountain range, and the beach touching each other.

Shomyo Falls is a great sight that’s right next to the Tateyama station where you’ll be going for snowsports such as skiing and snowboarding, as well as hiking.

What Is Shomyo Falls?

Shomyo Falls (称名滝) is the tallest year-round waterfall in Japan, with a drop of 350 meters. That’s taller than Tokyo Tower. Taller than a 100-story building. And the best part? You don’t just look at it. You walk up to it. You feel the spray on your skin. You hear it thunder through the valley.

In spring, the snowmelt adds another surprise: a second waterfall called Hannoki Falls appears right next to Shomyo. Two huge waterfalls crashing side-by-side like nature’s version of twin dragons.

In one word? Epic.

Why You’ll Regret Skipping It

I’m not here to scare you, but if you travel through Toyama and skip Shomyo Falls, you are missing the most jaw-dropping natural wonder in the entire region.

Let me paint a picture:

• You’re in Toyama. You’ve seen the Toyama Snow Wall.
• You’ve eaten Toyama Black Ramen and Firefly Squid.
• Maybe you even visited Gokayama’s UNESCO village.

Now imagine ending your trip standing beneath the tallest waterfall in Japan.

Now imagine not doing that.

The FOMO should be setting in. And it’s well earned.

What It Feels Like to Visit

The journey to Shomyo Falls starts with a drive or bus ride to the Shomyodaira Parking Lot. From there, it’s a scenic, paved walk through cedar forest and rocky canyons. You’ll hear the falls before you see them.

And then, around a bend in the trail — boom.

A wall of water. A roar of thunder. A cloud of mist.

It’s not just visual. You feel it. In your chest. In your bones. It is absolutely alive.

You stand on a wide viewing platform, with benches and railings. If it’s warm, you’ll get misted by the spray. You’ll want to stay for a while. I always do.

What Else Is Nearby?

• Tateyama Kurobe Alpine Route – Famous for snow walls in spring
• Kurobe Gorge Railway – Amazing fall foliage train ride
• Bijodaira Forest – Home to ancient trees and peaceful hikes

These can all be done in the same 1- to 2-day trip. Toyama is that compact and that good. But if you want to explore more, plan some more time. The Alpine Route will take you a full day.

Travel Tips from the Barefoot Surfer

• Wear appropriate footwear
• Bring snacks and water since this is far from the city
• Spring is my top pick — the sound is unreal

Final Thoughts: Come Before the Rest of the World Does

I’ve lived in Toyama long enough to know what’s real and what’s hype. Shomyo Falls is real. No neon lights. No paid photo spots. Just water, rock, sky, and time.

It’s not going to be so grand to be honest, but maybe that’s what makes it special. You can get back to the crowds after. Just enjoy the peace for now

So come. Feel the mist. Hear the roar. Let yourself be small next to something huge. You’ll remember it forever.
