> pronounced like the Japanese 上げ (with a hard g)

When mentioning pronouncing in Japanese, I would think that it would be better to use entirely kana, rather than kanji or mixed kanji/kana. (When writing actual words/sentences, I think mixed kanji/kana is better, but for writing pronounciation, I think kana alone is better.) (Note: I don't know so well understanding Japanese, but I can pronounce words written with kana, at least.)

At least some of the information, yes. Any information which is relevant to the use of the project should be mentioned in the documentation, including the license, although the documentation might not need to contain screenshots, a list of alternatives, etc.
