The water level of Lake Kawaguchi in Yamanashi Prefecture has dropped significantly, leaving the famous Rokkakudo connected to the shore. The hexagonal pavilion, which normally appears to float on the lake, sits on a small islet.

*Along the path to Rokkakudo, rocks from the exposed lakebed are scattered, with some stacked up by visitors.*

Since last summer, Lake Kawaguchi's water level has remained low due to below-average rainfall. Rokkakudo is usually accessible only by boat from the shore, but with the lakebed now exposed and a natural path formed, it can currently be reached on foot.

*Shells and dead aquatic plants scattered on the exposed lakebed.*

"The lake has been steadily drying up. About five years ago, swans would come here to lay eggs, and we could even see them swimming around with as many as nine chicks," said a couple who often visit from Fujiyoshida City. "But now, we hardly see them anymore."

*Shoreline patterns formed as the water level dropped.*

*Areas that are normally covered by the lake now look like ordinary ground.*

Exposed Area Continues to Expand

According to the Japan Meteorological Agency, Lake Kawaguchi recorded 1,080.5 mm of rainfall last year, well below the 10-year average of about 1,560 mm from 2016 to 2025. January saw 0.0 mm of rainfall. The prolonged lack of rain is considered one factor behind the declining water level.

*Clear water marks were visible on the piers of Kawaguchiko Bridge.*

According to the prefectural office that manages Lake Kawaguchi, the connection between Rokkakudo and the shore was first confirmed in late March last year, and the exposed area has continued to expand since then. The current water level is around four meters below normal.
