I looked at this slideshow article with a “you won’t gotcha me!” attitude, I have a Ph.D. in Religion thank you very much. But sure enough, they got me with the second one. I’ve never heard of a certain Japanese sect they describe.
The Vietnamese religion mentioned was also fuzzy for me, but I do recall studying it years ago in comparative religions.

Enjoy the vivid photographs while you’re at it.
