Here is my working draft of my notes as I worked through this:

2026-07-02JA-working.txt

There were a few different issues to resolve. This PR /mainly/ (but not perfectly) focuses on converting words that should be Katakana from Hiragana. We're assuming ~2nd grade reading level, so they will know Katakana.

What I tried not to focus on, but I jotted down as I was working was:

• Flagging Kanji, because that shouldn't have been passed over at all. The original ja.po needs reviewed in those places. Example: "周波数" for "frequency"
• Flagging English (Romaji) as some of those should be translated. Many times it was a block name that seems to have not been translated. Example: " Get-dict" or "get-red" or "Forever、Repeat、While、またはUntil。"
• Flagging something that needs some editorial decision or documentation. Example: The word for "code" and "chord" are now the exact same (コード) in some places. For "chord" we may want to disambiguate by putting コード（和音）
• Flagging something that just plain didn't make much sense. Example: "The Turtle sync block aligns the beat count between turtles." -- weird translation
• Flagging something where I just couldn't help but fix the translation, but that will make it diverge from ja (kanji). I think "nth mouse name" was one of those... (need to review my notes)

Hope this helps...
