A Guide to Visiting Nabegataki Falls: The Waterfall You Can Walk Behind

Nabegataki Falls is a wide, curtain-like waterfall in Oguni, on the northern edge of Kumamoto’s Aso region — and one of the few waterfalls in Japan you can actually walk behind. It isn’t tall, and it isn’t thunderous. The draw is the shallow cavern scooped out behind the water, where a softer band of rock has eroded back beneath a harder, lava-formed shelf, leaving just enough room to stand and watch the cascade from the inside. I went a couple of days after heavy rain, when the flow was at its fullest and the curtain really lived up to the name — and slipping around to the back of it is the whole reason to come.

Who Nabegataki suits — and who it doesn’t

It rewards anyone who likes quiet scenery and odd geology, and photographers do well here: light filters through the trees and the spray in soft rays the Japanese call komorebi. The walk itself is short.

It ends in stairs, though. The path from the parking lot drops more than 100 steps (locally counted at around 120). I didn’t find them hard going, but they’re steep and the ground near the basin stays wet and uneven — I wouldn’t send an older relative, or anyone unsteady on their feet, down to the bottom. There are no wheelchair-accessible routes to the falls.

Getting there

You’ll need a car — there’s no public transport to the site. The nearest bases are Kurokawa Onsen and Aso.

Starting Point	Travel Time (by Car)
Kurokawa Onsen	Approx. 20 minutes
Aso Station	Approx. 50 minutes
Kumamoto Airport	Approx. 1.5 hours
Hita IC (Expressway)	Approx. 1 hour

From the parking lot it’s a steep three-minute descent to the basin.

Tickets, fees, and the reservation system

Since November 2021, Nabegataki has officially run on advance online booking, brought in to manage crowds and protect the site. Reservations go through the official Webket ticketing page; phone bookings aren’t accepted. In practice, I turned up without one and still got in — so it isn’t always strictly enforced — but that’s not something to count on, especially during the spring illuminations, so I’d book ahead to be safe. You can usually reserve on the day itself if slots remain, and cancellations are allowed up to three days before your date.

Item	Cost (JPY)
Adult (high school and up)	¥300
Child (elementary / junior high)	¥150
Preschooler & younger	Free
Parking	Free

Hours are 9:00–17:00, with last entry at 16:30. The park is closed over New Year (December 28–January 3). Booking details and current notices are on the official Oguni tourism page.

When to go

The falls change completely through the year.

• Spring (late March–April): the short-run evening illuminations pull the biggest crowds and turn the falls almost theatrical.
• Summer (June–August): green, cool, and misty — a genuine escape from the heat.
• Autumn (October–November): the surrounding trees color up and frame the water.
• Winter (December–February): cold snaps can freeze parts of the falls into icicles, though the path gets slicker still.

One tip from my own visit: the falls are at their fullest a day or two after rain, so if the forecast has just cleared, that’s the time to go — just check first that the park hasn’t closed for high water. I arrived around midday, half-expecting flat light, and the sun coming down through the trees and the spray was the thing I remember most. Mornings are quieter for crowds, but don’t write off the middle of the day.

Before you go

• Wear proper shoes. Behind the falls and on the approach, everything is wet and slick — waterproof soles with grip, not sandals or heels.
• Check for closures. Heavy rain, high water, or typhoons can shut the park at short notice; confirm on the official Oguni site before you drive out.
• Mind the stairs. They’re manageable for most people but steep — a poor fit for anyone with balance or mobility concerns.
• Stay on the marked paths and viewing areas, for your safety and the site’s.
• Tripods are generally fine, but the space behind the water is narrow — keep an eye out for other people.

Worth pairing with a visit

• Kurokawa Onsen — a traditional hot-spring town 20 minutes away by car, known for its riverside open-air baths (rotenburo).
• Aso-Kuju National Park — the active Mount Aso, hiking trails, and the wide Kusasenri grassland.
• Daikanbo lookout — a panorama over the Aso caldera and its central peaks, about 40 minutes’ drive away.

Where to stay

There’s no lodging at the falls themselves. The practical bases are Aso or Kurokawa Onsen — Kurokawa’s ryokan are atmospheric but limited and pricey, so Aso usually gives you more choice for the money.

Is it worth it?

Nabegataki is less about scale than about a strange, close-up angle you don’t get at most waterfalls — standing in the dark behind the water and looking out through it. It takes a little planning: ideally book online, sort out a car, set aside about an hour on site. Go after rain, tie it to Kurokawa Onsen or Mount Aso, and it earns its place on a Kyushu route.
