We used the ANA arrival lounge at Narita(NRT) when travelling back from the UK.
The ANA arrival lounge can be used either using domestic flight or after arriving in NRT by NH flight.
The check-in desk is at the end of terminal 1, the lounge is just next to the counter, and it is before the security check.
Unlike the one at international departure, it is white-based lounge.
You can take some refreshments unlike standard domestic lounges.

No problem at all.
I think this lounge is also for business persons, same as Haneda(HND).
There is no kids space, too.
I think it is better to have it though.
