The water level of Kawaguchi lake is rapidly decreasing beside Mt. Fuji, “There is no natural outlet”
The water level of Kawaguchi lake is rapidly decreasing for some reason. Local newspaper comments it’s due to the shortage of rain, but because the lake has no natural outlet, it is hard to explain this rapid decrease of water only by evaporation.
Kawaguchi lake is located beside Mt. Fuji. Some experts suggets the possibility of the eruption of Mt. Fuji and Hakone.

Lake Kawaguchi (河口湖 Kawaguchi-ko?) is the one of the Fuji Five Lakes and located in Fujikawaguchiko, southern Yamanashi Prefecture near Mount Fuji, Japan. It is the second largest of the Fuji Five Lakes in terms of surface area, and is located at the lowest elevation. It is situated at an altitude of approximately 800 metres, which accounts for its relatively cool summers and frequently icy winters. It also has the longest shoreline of any of the Fuji Five Lakes.
The lake is within the borders of the Fuji-Hakone-Izu National Park. The lake has no natural outlet, and flooding of settlements on its shores was a problem until the construction of a canal, completed in 1914, to connect it to a tributary of the Sagami River.
It is reported that the water level decreased by 6m from 3/1 to 3/4/2013. However, Ministry of Land, Infrastructure, Transport and Tourism stopped updating the real time monitoring data for some reason.

Le niveau du lac Kawaguchi, à côté du Mt Fuji, diminue rapidement. Un journal local déclare que c’est à cause du manque de pluie mais il est difficile d’expliquer cette décrue rapide uniquement par évaporation et il n’a pas de déversoir naturel.
Le lac Kawaguchi (河口湖 Kawaguchi-ko?) est l’un des 5 lacs du Mt Fuji et il est situé à Fujikawaguchiko, au Sud de la préfecture de Yamanashi, près du Mont Fuji, au Japon. Il est, en terme de surfaces, le second des cinq lacs du Mt Fuji et il est aussi le moins haut en altitude. Celle-ci est à environ 800 mètres, ce qui joue sur ses été relativement doux et ses fréquentes gelées l’hiver. Il a aussi la plus longue des lignes de rivages des cinq lacs du Mt Fuji.
Le lac est à la frontière du Parc National de Fuji-Hakone-Izu. Ce lac n’a pas de déversoir naturel et l’inondation des habitations de ses rivages a été un problème jusqu’à la construction d’un canal, achevé en 1914, pour le relier en affluent au fleuve Sagami.
On rapporte que son niveau a baissé de 6 m entre le 1er et le 4 mars 2013. En outre, le ministère du Foncier, des Infrastructures, du Transport et du Tourisme a arrêté sans explication de mettre à jour les données de surveillance en temps réel.

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
