June trade-offs
- ↓250mm of rain — the wettest month; persistent overcast and daily heavy showers are the norm
- ↓Mt Fuji invisible for most or all of the month — lake reflections and ropeway views largely wasted
- ↓Only 4 hours of sunshine daily; the mountain atmosphere is oppressively grey and muggy
December trade-offs
- ↓Cold: 2°C lows require proper layering for all outdoor activities including ropeway and lake walks
- ↓Christmas and New Year week (Dec 28–Jan 3) sees a brief price and crowd spike
- ↓Short daylight hours limit afternoon photography windows; the golden hour arrives before 4:30pm
