Easiest way to make a booking for a Mt Fuji mountain hut?
Any easy way to book? Most are full on the day I want and it requires calling them directly.
I was told that booking is not necessary and it's still possible to stay there, is that true?
Some websites say that reservations are not necessary, but are recommended. Japan National Tourist Organisation says that you will need to make reservations to secure your space in the hut http://www.jnto.go.jp/eng/arrange/travel/practical/pdf/Mt.Hut_Mt.Fuji.pdf
This website, for example, helps to book a hut http://www.fujimountainguides.com/mountain-hut-reservations.html
I climbed Mt. Fuji two years ago. We reserved when we went up, and it was a busy night. There is only a limited number of huts, and by the time you've walked past the first few, it's not long before you run out of options and have to head back down to the earlier ones again. That said, I felt there was plenty of room for a few extra bodies, so if you don't feel confident about booking in Japanese, probably you don't need to worry too much about it.
Another thing is that in any case, getting a space in a hut isn't as great as you might think. Firstly, it's quite hard to get to sleep, because there are so many people coming and going, and if you're trying to get some shut eye in time for a sunrise ascent, then in any case you're going to have to get up and leave by midnight. So all-in-all, you might only get 3-4 hours sleep. Hardly seems worth the effort and if I was to climb again, I'd forget about the huts and instead take warmer clothing and a ground sheet so that I could have a lie down up the top before the sunrise.
Remember, too, that EVERYONE wants to see the sunrise, so unless you're at the summit before 03:30am, you're likely to get stuck in the human traffic jam that will occur any later than that. Another good reason not to stay in the huts but instead to surefoot it directly to the top.
