Sekinoo Falls, Miyakonojo: Pothole Field

Sekinoo Falls in Miyakonojo, Miyazaki Prefecture, is a celebrated waterfall within the Kirishima-Kinkowan National Park and Kirishima Geopark, and one of Japan top 100 waterfalls. The great cascade thunders down in a spray of mist. Though modest as a tourist site, it is a hidden spot where you can feel the power of nature.

The greatest highlight is the field of river potholes spreading above the falls. Formed as pebbles spun by the current carved cylindrical holes into the bedrock over vast stretches of time, the field is said to be among the largest in the world and is designated a national natural monument. The falls consist of a main cascade and a smaller one, and a walking path and suspension bridge are laid out around them.

Highlights

• The powerful main falls crashing down with a roar, viewable up close from the lookout.
• The large field of potholes upstream, with shapes carved over the ages that are simply breathtaking, designated a national natural monument.
• The view from the Sekinoo suspension bridge over the falls, taking in the flow and the greenery at a glance.
• The quieter smaller falls along the path, showing a delicate, graceful character different from the main cascade.

Practical Travel Notes

Practical advice from the TabiTabi Japan editorial team.

• The potholes can be observed from the riverside path above the falls. Access may be restricted when the water is high, so if you want a close look, choose a day when the level has settled.
• The suspension bridge offers a view of the whole falls. If you are uneasy with heights, do not push on; the lookout deck still gives a powerful view.
• After heavy rain or a typhoon, the paths are slippery and may be closed. Check conditions with Miyakonojo or on-site information before your visit.
• Central Miyakonojo has sights such as the Miyakonojo Shimazu residence and local shochu distilleries. Pairing the falls with these makes a satisfying half-day plan.

A Quick Tip

The falls are most powerful when the water is high, but if you want to observe the potholes closely, choose a day when the water level has settled. Making a full circuit of the main falls, the smaller falls, and the pothole field lets you savor the beauty of form carved by nature over endless time. Visit in comfortable shoes and allow yourself plenty of time.
