First, sorry for lack of photo....
When I arrive at New Chitose Airport after some crazy driving to return the car, I came off the Toyota feeder service and head to JAL counter. JAL counter @ CTS kind of split into 2 part, 1 for the general public, and the other for the First Class passenger (and JMB / JGC Elites).
As I am holding a Y ticket and need to have paid upgrade, I head to their ticketing counter with my e-ticket and request upgrade. After signing my card and give JAL 8,000 JPY (96 USD) I got a First Class ticket and bunch of invoices.

I head to the normal baggage check-in counter as I am lazy to walk and there's no queue anyway, checked my luggage and I am ready to go. The luggage agent actually odd that a First class passenger check luggage there and do the priority tag right after seeing the First class tag.
So after wandering in the CTS landside a while (man they have the best shopping area in all Japan's airport I guess, all you can buy seafood and souvenir) I go to the First Class security. Yes, they actually have dedicated security channel for their F passenger, and it directly connects to their lounge. The security was a breeze as I am the only guy there (and it was a low day), after like 5 minutes I am already in lounge enjoying the Sapporo Classic Beer
The lounge let me down a bit though. There's only drink service and some rice crackers, and that's all, no even biscuits! So after a few beer I decide to go back to landside for some food. The agent is pretty helpful and as it's domestic, no annoying immigration and I am there in 2 minutes.
The good thing of Chitose is you can get pretty much any food you want, and I got a melon icecream and kani benton (crab lunch box) from the shop there. price is OK for Japan standard but on the expensive for me as HK-er
After buying the food I go though the security again, which only takes 2 minutes as I left all my stuff @ lounge reception, and enjoy my late lunch.
