A lot of training data was curated in Kenya[0]. I would imagine if LLM data was curated in Japan our LLMs would sound a lot like the authors of their most popular English text books. Maybe other common Japanese idioms would leak in to the training data, like "ね" or "でしょう", ChatGPT would say "Don't you agree?" at the end of every message.
The Indian-born textbook author mentioned (Malkiat Singh [0]) had an inordinate influence on many Kenyan students because his textbooks were the de-facto standard for years. Its interesting how this influence extends as his students get to curate the LLMs on which the world has come to rely.
Maybe we all should start writing Japanglish to show our authenticity? Or rather, ”Maybe we all should start writing the Japanglish, so that peoples can feel our real soul, you know?”
