Maybe it is per-se. Overall the Japanese diet is substantially more healthy than the US one. However Japan is also quite a white rice heavy diet on average, so comparable to the US's preponderance for processed bread. So if you're not careful in Japan you can quite easily go days without much fibre – it is much easier to get a healthy meal in Japan, but its also easy to get poor meals in Japan (e.g. 7-11 snacks) !
However the thing about Japan is they have an aggressive annual health screening programme which is mandated by law for all employed individuals (twice per year for those working in hazardous environment).
So the more interesting question for Japan might be in relation to early diagnosis and associated outcomes. I suspect both would be materially better than in the US but I haven't gone looking for the data.

I’m actually surprised by the placement of some of these countries. I assumed Japan would be much lower.

Measured rates are not as straightforward as they seem
It's always a mix of the "true rate" vs screening/detection rates vs "dying of other things before detection" rate
