Catholicism in particular because it has the unique visuals and audios like uniforms (priests, nuns, monks clothes), pictures, LATIN, Gregorian chant, incense, the mass and, until recently, there was an established Imperial Roman fascismo Arditi vibe . Nowadays, I'd invite any Japanese lady or gent to go to a mainstream Catholic Church and see how outdated their perception of Catholicism is. It's way more modern, and under Francis, more gay and transgender friendly than a fundamental Baptist church. Times have changed.
