Protect the return
Treat the homeward service as part of the excursion rather than something to improvise after sunset.

Make transport visible, then preserve alternatives for changing visibility.
Kawaguchiko is a weather decision wrapped around a transport decision. Secure a realistic way there and back, but avoid making one viewpoint the only definition of a successful day.
Keep several lake-side activities that still work with changing visibility and decide in advance what would make you move the excursion to another date. Flexibility is a planning asset, not a failure to commit.
Plan this destinationTreat the homeward service as part of the excursion rather than something to improvise after sunset.
Choose when to keep, move or replace the day before non-refundable surrounding plans make that decision impossible.
Combine the lake, food and one indoor or low-visibility option so the trip retains value in imperfect conditions.
The earliest fixed commitment tracked in Kawaguchiko is Tokyo–Kawaguchiko highway bus, opening 1 month before the visit. Set that date first: it is the one that decides how early the rest of this city has to be settled.
For the Shinjuku–Fuji Five Lakes route, sales open at 04:00 JST on the same date one month before travel.
