Nabegataki Falls

Nabegataki Falls, Kumamoto: The Waterfall You Can Walk Behind If you're heading to Kumamoto and want somewhere a little quieter than the usual stops, I'd put Nabegataki Falls on the list. It's known as the waterfall you can walk behind — you actually stand in a hollow space behind the water and look out through it like a curtain, instead of just viewing it from across the river. The best part is how it looks from that angle. The water spreads wide and thin across a curved rock ledge rather than dropping straight down, so from behind it, it really does look like a sheer curtain with light filtering through. It's about 10 meters high and 20 meters wide, and it's said to have formed from the same eruption that created the Aso caldera around 90,000 years ago. It wasn't always a tourist spot — it stayed pretty local for years until a Japanese tea commercial with actress Nanako Matsushima was filmed there, after which more people started coming. It's still nowhere near as busy or well-known internationally as somewhere like Kyoto, though, so it still has that "found it myself" feeling. A few tips: from the parking lot it's about a 5-minute walk down, mostly stairs through the woods, so it's not really a hike, more of a short walk. No wheelchair or stroller access, and the path near the water gets wet and a bit mossy, so wear proper shoes rather than sandals. Most people spend around 40 minutes to an hour there if you want to see it from the front, side, and behind. Booking online in advance is recommended — same-day tickets are sometimes available through the local tourism office, but they're not guaranteed, especially on weekends. There's a decent-sized car park on site, though it fills up during busy periods. In spring there's also a night illumination event, where the falls are lit up from behind — apparently a very different atmosphere from a daytime visit, so worth timing your trip around if you can. Opening hours are 9:00–17:00, with last entry at 16:30 (this can shift slightly by season). Entry is 300 yen for adults and 150 yen for elementary/middle school students. There's no train access, so you'll need a car or a tour — from central Aso it's roughly a 40-minute drive. If you're already exploring the Aso area, it's an easy add-on, and honestly one of the more memorable short stops I've come across.
