This makes me wonder, what’s the iMessage situation in Japan? Their smartphone market is also majority iOS, sitting at above 60% (while it is only a little bit above 50% for the US)[0].

LINE absolutely dominates the Japanese market in instant messaging and beyond (it's a super app like WeChat or KakaoTalk).
Thanks to your point, this way we can easily see that despite SK being android-dominant and Japan being iPhone-dominant, both are not heavily into iMessage and prefer their native super apps instead.
Which provides a solid data point in favor of those claiming that the iMessage proliferation and dominance don’t necessarily have a direct causation stemming from iOS/Android dominance in a given market.
