Imuta is a crater lake about four kilometres round, sixty hectares in area, and remarkably shallow — the deepest point is 2.7 metres and the average is eighty centimetres. That shallowness is what makes it unusual. The western third has silted up into low moor, dead reeds and willow have accumulated into peat, and sections of that peat have broken free and float. The result is a lake with drifting islands of vegetation on it.

The peat-forming community is a national natural monument and the lake was listed under the Ramsar Convention in 2005. There is a four-kilometre path round the shore, boat and cycle hire, and it is a well-known spot for dragonflies — over sixty species — and for wintering waterfowl. It sits in a bowl of low mountains inland from Satsumasendai and receives very few visitors.

Insider Guide

**Look for the floating peat.** Sections of the peat layer detach and drift, which is what the natural monument designation is for. They are on the western side where the moor is. **Four kilometres round.** The shore path is flat and takes about an hour on foot, less by bicycle. Cycles can be hired at the lakeside. **Dragonflies from early summer.** More than sixty species have been recorded, which for a single small lake is exceptional, and midsummer is when the diversity shows. **Winter for waterfowl.** Ducks and other migratory birds use the lake through the cold months, which is the other reason it is Ramsar-listed. **Combine with Iriki.** The samurai district is about twenty-five minutes away, and the two make a full day inland from Satsumasendai.
