Aokigahara Jukai "Suicide" Forest
This video takes place in the Aokigahara Jukai Forest between the Wind Cave and the Ice Cave near Lake Saiko, one of the Fuji Five Lakes.
The geology is amazing as it is all volcanic.. barf from a major eruption of Mt. Fuji from 864-868AD. The elevation of the lake is 900m (3,000ft), exactly the same as neighbouring Lake Shoji and Lake Motosu. The reason is that before the eruption these three lakes were all one big lake, but the lava flow was so huge that it separated them. They are apparently still connected underground.
The Aokigahara Jukai Forest you are about to see has grown over the lava flow over the past 1,200+ years, but as the ground is all lava rock, the roots have nowhere to go. Thus they grow up and around the lava rock in amazing (and grotesquely beautiful) formations. You can read more details on Lake Saiko and the Aokigahara "Suicide Forest" in Wikipedia if you would like to search.
You can also find some deeper information on the Ice and Wind Caves in the area (as well as the Bat Cave, which we didn't visit, but I would have likes to as we might have had the opportunity to meet Alfred, or if the goddess of fortune were with us, Bruce.) Since we can't post links (I don't think) to information in the videos, let me say that the "link" I am about to include states that the Ice Caves have been used since the early 1900s, but information at site says that "it is believed that" the ice was carved out and transported from these caves to Edo (Tokyo) for the Shogun and his lords to enjoy (that would be from the 1500s and on).

I can't imagine how they could have transported ice blocks for (about 5) days on horseback without them melting, except perhaps by insulating them with straw. But the "ancients" had technologies that confound even the best scientists of our day, so nothing would surprise me. Even so, in the hot summers one would think the load would be considerably lighter after four or five days travel by horse. I wonder how many vassals had to commit suicide after being ordered to "bring us ice", arriving in front of the lord, only to find the ice had melted and was gone? "You have failed me... I am sorely disappointed in your efforts...." After leaving the overlord's presence, to a buddy, the following statement was likely overheard numerous times: "Say goodby to my wife and children, will you?" And, "Hey, can I have your Katana? You won't be needing it any more." Imagine the stress of being chosen to "bring ice"!!
