>>2446382You need way more than 2,000 yen for the stamps. I just did it at the beginning of the month and I think it was more like 6,000-ish yen for every stamp we could get.
>>2444795If you're spending the night at a hut, it's a pretty nice way to do it, but if you're summiting and descending all in one go you're going to be tired so I hope you have some place to stay the night nearby when you get down. The route itself isn't that bad, it's just got a million switchbacks up and down so it's just real long.
Make sure to bring enough water. The ascent for me was covered in clouds so I never got that hot, but going down the sun came out and the volcanic soil bakes you from underneath. I think I used about 3 liters and was still dehydrated.
Take the ascent slowly, don't feel like you have to sprint up the mountain. If the route to the summit gets backed up, you'll have to do this anyway because a weird queue forms.
It is freezing at the top, so make sure you bring layers.
Bring plenty of yen for random bullshit (they sell all sorts of crap at every hut, souvenirs, food, drinks, etc) and you have to use yen coins to the use the bathroom. You can even get a fairly cheap meal at the summit, which is well worth it. Depending on the route you take, some routes have the huts only on the way up and not the way down, so plan accordingly. A lot of huts operate 24/7 or open at midnight.
I suggest public transport to the 5th station and taking the train from Tokyo. Don't bother renting a car, you'll have to pay a toll if you drive and sometimes the road up is just closed to cars.
