Latinized Japanese texts
I am preparing a booklet on four 17th-century Japanese books written in Manila by a Spanish priest who wanted to convert the Japanese. He didn't use any Japanese logogram nor any Japanese syllabogram. His texts are only in Latin characters. I transcribed the one-page long titles into Japanese characters, while my presentation and translations are in English. My question is about the front cover. Which one do you like best? The one with green or the one with violet? (The vertical title is simply the Japanese translation of the English title. )
