Fun! These tiny cryptics are actually really good practice; I'm finally starting to get more clues in bigger cryptics.
Side note: funny that both of our puzzles reference Japan — I'm currently staying in Hiroshima!!
Not bad, although I do have to point out that it's usually frowned upon to not have the anagram fodder in the clue verbatim. It's not a big deal with something this checked and this small, but keep that in mind.
Anyway, very nice nonetheless. I can see your clueing improve!
Cool! It’s not so bad with short answers like these, but just a note that “indirect anagrams” like 3D can end up feeling too unfair and so aren’t often used. Great to see your clueing getting better!
