Japan water shortages hit Mount Fuji

Japan’s Golden Week travel crunch around Mount Fuji is not just about crowds this year. It’s about missing water. Lakes in the Fuji area have dropped enough that sightseeing boats are changing routes or stopping altogether, and other tourism businesses are trimming hours right in the middle of one of Japan’s busiest holiday stretches. Why does that matter? Because the Mount Fuji lake district is built around water-based sightseeing. The Fuji Five Lakes area is one of Yamanashi’s biggest tourism draws, with excursion boats, lakeside hotels, hot springs, and the postcard views most visitors actually come for. When lake levels fall, the problem is not abstract — piers stop working, boats cannot dock normally, and the whole visitor flow gets awkward fast. What actually changed this week is pretty specific. Fujigoko Kisen, a local sightseeing boat operator, suspended service on Lake Motosu and changed routes on Lake Kawaguchi because water levels have kept falling since last year. The operator’s head, Kazuya Fujii, said levels had rarely dropped that far. That gives you the scale of the issue — this is not a routine seasonal wobble. And it is not only the Fuji area. Lake Chuzenji in Nikko, northwest of Tokyo, is dealing with the same kind of disruption. Tobu Kogyo’s sightseeing boats usually use three piers there, but low water has made those piers unusable, so they have been cut from the route. Basically, the tourism map is still there, but some of the infrastructure that makes it work has stopped matching the shoreline. So why is Japan short on water in tourist spots now? The simple answer is a long dry spell. The reporting ties the shortages to low rainfall since last summer. That matters because lakes and tourism facilities do not break all at once. First the waterline retreats. Then docking gets tricky. Then operators start shortening hours, rerouting, or suspending service because the normal setup no longer works safely or efficiently. Why does Mount Fuji make the story feel bigger? Because this is one of Japan’s highest-visibility travel regions. The Fujikawaguchiko area on Fuji’s north side is a core gateway for domestic holiday travelers and international visitors. During Golden Week — which in 2026 runs from April 29 to May 6 — demand is already packed. Any disruption lands harder because there is very little slack in the system. There is also a second squeeze. Fujii mentioned soaring fuel prices alongside the water shortage. That means operators are getting hit from both directions — physical limits from low water and cost pressure from running boats and tourism services. Even if visitors still come, the catch is that businesses have less room to absorb disruption without cutting something. The bottom line is that this is a travel story, but really it is a climate-and-infrastructure story showing up in a tourist hotspot. Mount Fuji itself has not changed. The lakes around it have. And when the waterline moves, the holiday experience people planned around can move with it.
