I remember some facts about an international auxiliary language (IAL) created by a Japanese person, but unfortunately I both forgot the name of the inventor and the name of the IAL. Can someone help me out?

Features that I can remember:

  • Created by a Japanese around the turn of 19th to the 20th century
  • Based on European languages (mostly latinate vocabulary)
  • Having a schematic and simplified inflection
  • When the author became aware of Esperanto he dumped his own IAL project and became one of the first Japanese Esperantists

I want to know the name of the author and (if available) the name of the language. Additional information is always welcome!

Assuming that the OP misremembered a few facts, the language may be Babm, invented by the Japanese philosopher Rikichi [Fuishiki] Okamoto (1885–1963) and first published in 1962. It uses the Latin script as a syllabary (which is not the same thing as using a latinate vocabulary) and has "some degree of analytic inflection".

    I thought of Babm too, but its vocabulary is completely schematic, and the date is wrong. Apr 4, 2018 at 5:27

I have found the language again, it is named Zilengo and it was designed by OKA Asajiro in 1890. Apparently not much information about the language is preserved.


The only auxlang I've heard of being made by a Japanese person is Noxilo, but that's a modern invention. To my knowledge, the original creator is still alive. Noxilo is just a word-for-word cipher of Japanese btw. Even the phoneme inventory and orthography is clearly Japanese.
