About Lake Ikeda

Lake Ikeda is a round lake formed in a volcanic crater, about 10 km west of central Ibusuki. With roughly 15 km of shoreline and more than 200 meters deep, it is Kyushu’s largest lake. The water is deep blue, and Mount Kaimon, a nearly perfect 924-meter cone also called Satsuma Fuji, appears on the southern side.

The lake is known for giant eels, the oounagi, which can exceed one and a half meters in length. Some are kept in tanks at the lakeside park, where they can be seen up close. Local legend speaks of a monster in the lake, Issie, who became the region’s mascot.

In early year, generally January and February, fields of canola usually bloom along the shore in yellow with Mount Kaimon in the background. There is a lookout at the north shore park and a road that circles the lake with stopping points.

Mount Kaimon can be climbed by a spiral trail of about 5 hours round trip, with views of the ocean and the islands to the south. Closer to the coast are Cape Nagasakibana, the southernmost point of the Satsuma Peninsula, with a lighthouse and views of the mountain, and Lake Unagi, smaller, where steam from the shoreline hot springs is used by locals to cook vegetables and eggs in stone ovens called sumege.

Before you go

Practical information

Cidade Turismo reviews its information regularly, but something may have changed. Check with the place before planning your trip.

How much time to set aside

About 1 hour in the lakeside park and lookout; half a day with a drive around the lake and a stop at Cape Nagasakibana.

Best time

In the morning, when Mount Kaimon often appears cloud-free. In January and February the canola flowers usually bloom; in summer humidity can hide the cone.

How to get there

It is about 11 km from central Ibusuki, 20 minutes by car or taxi. Local buses from Ibusuki Station serve the lake, with few departures per day; check return times.

Tip

Combine the lake with Cape Nagasakibana and Mount Kaimon in the same outing by car or taxi. To photograph the mountain reflected in the water, prefer the north shore in the morning.
