I recently came across Oomoto, a Japanese religion originating in the 19th century. Wikipedia: https://en.m.wikipedia.org/wiki/Oomoto Their own website: http://www.oomoto.or.jp/English/index-en.html That 19th century! It gave us so many new religions and reform movements, in Judaism (reform and so on), in Christianity (too many for me to remember, LDS and Christian Science), in Islam (Baha'i)... and also in Shinto, with Oomoto. They embraced Esperanto! A bit like the Baha'is initially (Lidya Zamenhof, Daughter of Dr. Esperanto, translated some Baha'i textx into Esperanto)... Fascinating parallels. To invoke a concept that fell out of favor in the scholarly world: Almost like a second Axial Age.
