Almost everyone who is really trying to live the self sufficient lifestyle has heard of Tom Neale, the New Zealander who lived the last part of his life on a deserted island. Lots of people have read his book, which is excellent.
The old gentleman in the Japanese film had chosen to do the same thing. I was really surprised at the many similarities between his life, and the way Neale lived. They had a lot in common in terms of their philosophies of how mankind should coexist with nature.
Neal always put on some shorts when visitors arrived at his island, and went stark the rest of the time.
The Japanese are totally unconcerned about nudity, it's part of their culture. So the fellow in the Japanese video stayed in the buff. They blurred out any parts of his anatomy that might make westerners fall over in a dead faint though.
The other thing that's different ,is that the Japanese have a very natural sense of humor, and aren't embarrassed by things we would consider vulgar. When I was in Japan in 1979-1980 for 13 months, I sometimes watched Japanese television and I would be amazed at some of the shows and advertisements. At the time, if anyone had put some of those things on American TV they'd have gone to prison. So you'll notice one instance when the old guy on the island makes a joke that we would consider very coarse, but it really isn't if you think about it.
The "hermit"was very articulate and I thought a lot of what he said was spot on. I watched the whole thing, something I almost never manage to do with youtube videos unless they are really short.
The man is a first class survivalist, although he probably doesn't think of himself that way.
