About Lakes Sai, Shoji and Motosu
To the west of Lake Kawaguchi are three of the Fuji Five Lakes: Sai (Saiko), Shoji (Shojiko) and Motosu (Motosuko). Sai and Shoji used to be a single lake, split by lava from a large 9th-century eruption, and the three are connected underground: their water levels rise and fall together. They are less developed than Kawaguchi, with campgrounds, small inns and forested shores.
Lake Sai is the closest, with calm waters used for kayaking and fishing. Between it and Mount Fuji lies the Aokigahara forest, which grew over lava and has a rocky ground covered in moss. At the forest’s edge, two lava caves can be visited from the inside: Fugaku Wind Cave and Narusawa Ice Cave, where ice remains all year.
Lake Shoji is the smallest of the five, surrounded by mountains, with a view of Fuji that appears behind a smaller hill, Omuro, which earned it the nickname “Fuji with the child on its lap.” Lake Motosu, the deepest and clearest of the group, has the Nakanoshima viewpoint on its northern shore, offering a view of the cone over the water, and nearby there is a pink moss flower festival, generally from April to May.
The three lakes are linked by the road that circles Fuji to the north and by sightseeing buses that depart from Kawaguchiko Station. The landscape is quieter and more rural than Kawaguchi’s, and the area is popular for camping, paddling and hiking.
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
Half a day to see the three lakes and one of the caves; a full day if you plan to hike.
Best time
Early morning, when Fuji is often visible, especially in autumn and winter. The pink moss festival near Lake Motosu typically runs from mid-April to May. In winter, the shores can have ice.
How to get there
The green sightseeing buses, the Saiko Sightseeing Bus, depart from Kawaguchiko Station and reach Lake Sai in about 30–40 minutes; services to Shoji and Motosu are less frequent. By car, Lake Motosu is about 25 km from the station.
Tip
Visit Fugaku Wind Cave and the Ice Cave in the same outing: they are about a 15-minute walk from each other. Bring warm clothing, because interior temperatures stay near zero even in summer.
