Mountain Hut at Mt. Fuji

I have problems finding a budget Hut at 8th station. It is all in japanese. We will arrive from Nikko. Am I to late to find a place to rest - it is between the 22nd and the 23rd of July 2014

Some huts begin its reservation in April but the most huts begin in May or early June.
