I’ve noticed that for a lot of kanji subjects delivered by the API, some of the visually similar subject IDs are duplicated. For example for subject 933, the kanji “Clear Up”:
“visually_similar_subject_ids”: [
864,
891,
1386,
1356,
1052,
1370,
2319,
864,
891,
1386,
1356,
1052,
1370,
2319
],
Not a big deal, obviously, but I wanted to let you know just in case.
