If you don’t mind becoming severely sore just for an awesome sunrise, then do it. The ascent wasn’t so bad but it was descending that killed me; slippery rocks, boring view, and seeming unending zig zags.
If you do go, be sure to time it right so you can catch the sunrise . I wouldn’t want to endure that pain just to say I climbed Mt. Fuji, but the sun cracking over the clouds does ease the pain.
