The Ochudo trail - Mount Fuji

I'm interested in hiking the FULL Ochudo trail completely circling Mt. Fuji (~2500m amsl) but can't find any information/map (English) regarding the full trail. I know the trail drops somewhere below the Osawa Kizure (Osawa collapse) and back up again but is that section easy to follow? Is it a clear trail? A couple of weeks ago I spoke to a few Japanese people at the Fujinomiya 5th station restaurant that were about to hike this full circle route (~22km?) and encouraged me to try it. (I was already doing the Sea2Summit of Fuji at the time)
