Yes, they are flexible.
JAL staff never recommend it to go back to immigration after proceeding to the lounge.
Also, it is not recommended to leave luggage in the lounge for long time due to the security reason(unattended luggage).
However, I have never denied to go back to the immigration through security.
Always, I showed my boarding pass and said my flight will depart at night and I want to do some shopping.
Even I say the same thing at Immigration and customs and never be denied.
By the way, I used ANA last time and asked to hold my carry on luggage at concierge desk until my flight time(also 8 pm).
Without any problem, she held it at their back office until my departure time.
I think JAL can do the same if we ask.
(I guess only first class lounge has keyed locker)
