FUJI SAMURAI WEATHER
This page organises information published by the Japan Meteorological Agency for travellers heading to Mt. Fuji and Lake Kawaguchi. It is not a Fuji Samurai forecast, and it is not a judgement about whether conditions are safe.
Warnings and advisories
The agency issues warnings for the Eastern Yamanashi · Fuji Five Lakes district. For the wording of any warning in English, see the agency’s own page linked at the foot of this page.

Agency forecast figures
Forecast figures could not be retrieved just now.
Fuji Samurai publishes the agency’s numbers only. We do not translate the agency’s written forecast, because we have no verified official English wording for it — read it in English on the agency’s own page instead.
Daylight
Calculated for the Lake Kawaguchi area at sea level. Times on the mountain differ with altitude and terrain.
Read it at the source, in English
How to read this page. Everything above is published by the Japan Meteorological Agency and reproduced without adjustment. Fuji Samurai does not produce its own forecast, does not decide whether the weather is good or bad, and does not advise whether it is safe to climb or travel. Conditions on Mt. Fuji change quickly and differ sharply with altitude — please check the agency’s own pages and the relevant local authority before you set out.
