The issue here is more than age of consent. The point of contention here is whether he's committed infidelity, which is punishable in Japan where her wife could divorce him on that ground and claim alimony. This is why he and his acquaintance keep stressing he didn't cross the line(physical relationship).
Cheating, affair and infidelity
https://hataraquest.com/cheating-evidence
In the first place, the difference between “cheating” and “affair” is easily confused, but strictly speaking, the meaning is different.
In general, cheating often refers to a general relationship with a person other than your spouse who is in love or is suspected.
It is also used between lovers who are not married.
On the other hand, infidelity is often used in the sense of having a physical relationship with the opposite sex other than the spouse, that is, having sex. It is also a term used between married couples.
However, neither is actually a legal concept, and the affair of a spouse who is legally married is called “unfaithfulness”.
The reason why it is necessary to distinguish between cheating and infidelity (unfaithfulness) is that legal claims for “claim for alimony” and “claim for divorce” are not allowed unless they are infidelity (unfaithfulness).
