Why does it matter what script tag to apply if there are no opentype
interactions with Japanese?

On the other hand, I have just remembered one interaction: a pan-CJK
font such as Source Han Sans / Noto Sans CJK will have variant forms of
the kanji for Chinese, Japanese and Korean. But even then the selection
should be done on language, not on script - I haven't checked how it works.

So if pushed I would say Kana, just in case. But it really shouldn't matter.
