I love the JAL First Suite.
It is far superior to First Solo.
Even comparing to ANA new First(not new anymore though), I prefer JAL.
It is one of the most comfortable sleeper seat.
OP, did you eat too much during the flight???
You must be full if you ate everything on your pictures

Also, did you try Japanese Curry at First Class Lounge(I did not see on your pictures)?
I love the Curry,too
