I've seen a lot of your suggestions. Can't say I am impressed. I'm a tad disappointed, but that's probably due to the limited selection all of you seem to have had.
ThuleanPerspective
(The best I can describe the name behind this channel Varg Vikernes is a Pagan cynic. Former Burzum-Mayhem band member turned self-defence/"murder" case pariah, survivalist, permaculture farmer, father of 6, etc…)

https://www.youtube.com/channel/UCZAENaOaceQUMd84GDc26EAFind Your Love in Japan
(Trying to explain this person's position is a bit odd. He doesn't seem like a nationalist, he doesn't seem like a traditionalist, and he doesn't seem like any kind of radical. But, you can sense some of these elements in him. I'd say he's an average Japanese person communicating their values to a Western audience. He frequently reports the average Japanese person's opinion and a range of other sorts.)
