Fuji-san has been referred to in previous threads but a few points:

- Visibility is very poor on most days and you might not be able to see any of the mountain even from close distance

- Some of the surrounding area is a national park but there are also industrial cities and a Japanese SDF/US Army shooting range nearby

- The mountainside stations with road access are nothing to write home about if the weather is foggy. Mediocre food and souvernirs. If you want to get the "real Fuji experience" it would mean a night climb on foot and arriving on the top by daybreak. It's a bit chilly up there as well...

So I'd just repeat my advice from two years ago and recommend to admire Fuji-san from any Tokyo highrise over a single malt or glass of claret.
