My kids did it as a day trip from Tokyo, but the weather on Fuji turned foul, and it was late night before they returned; a very long day. The warning on hypothermia should be noted: they were dressed for July heat, got soaked, and made it through with maybe 100 cups of hot tea at the top station.

They could scarcely walk when they got back to the hotel, but both treasure their Fuji sticks.
