Lake Toya
A living volcano wrapped around a very calm lake
For travellers heading between Sapporo and Hakodate who want a full day on a lake that is prettier, and more volcanic, than it looks.

Boat to Nakajima
The Hokuto limited express stops at Toya station, and the Donan bus takes about 20 minutes to Toyako Onsen on the south shore; aim for the pier around 10:00. Sightseeing boats circle the lake in about 50 minutes and in the warmer months land on Nakajima, the wooded island in the middle where deer wander a short nature trail. The rim of the caldera and the cone of Yotei are the views on the way out.
1 HourCost: ¥1,500–2,000 - 2
Toyako Visitor Center and Volcano Science Museum
Next to the bus terminal, the visitor centre explains how Usu has erupted roughly every few decades and shows what the most recent eruption did to this town; the science museum on the same site has a shaking-floor theatre. Twenty minutes here makes the crater walk that follows make sense. Lunch on the lakefront street after, where hotels serve Hokkaido seafood set menus.
45 MinutesCost: Free 
3Nishiyama Crater Trail
A bus or 30-minute walk west of the onsen town brings you to the Nishiyama trail, a boardwalk through the craters that opened on the edge of town in the most recent eruption. The road that once ran straight through here is still there, buckled and half-swallowed, with a kindergarten and a factory left as they were. It closes in winter and on days with high gas readings.
1 HourCost: Free- 4
Usuzan Ropeway and Showa Shinzan
The Donan bus continues about 15 minutes to the base of Showa Shinzan, the rust-red lava dome that pushed up out of a wheat field within living memory. The ropeway climbs Usuzan in six minutes to a terrace over the lake, and a short walk leads to the lookout into the summit crater. Go around 15:00 when the afternoon light lands on the dome.
1.5 HoursCost: ¥1,500–2,500 
5Lakeside baths and the summer fireworks
Back at Toyako Onsen, free foot baths line the lakeside promenade and most hotels open their big baths to day visitors in the late afternoon; pick one with an outdoor pool facing the water. From late April to the end of October a fireworks barge sails along the shore every evening after dark, so a late bus or an overnight here is the natural end to the day.
1.5 HoursCost: ¥500–1,500

Tips
Toya station is on the lake's far side from the town; count the 20-minute bus in both directions when you pick your trains.
The Nishiyama boardwalk is uneven and can be muddy: trainers with grip, and a windproof layer for the ropeway terrace.
Try the local scallops and the Toya beef at lunch; dinner options thin out once the day-trip buses leave.
From the ropeway terrace, shoot the dome with the lake behind it, then turn around for Yotei floating above the far rim.
