I.A.S.S Executive Lounge 1 — Local services in Narita

This is the IASS Executive Lounge on the 5th floor on the land side of the International Terminal 1, meaning you can get in before going through the security check to the boarding gates. Not to be mistaken from the IASS Superior Lounge, which is on the air side of Terminal 1. We arrived early for our flight before the check-in counter was open. We have Priority Pass and we were allowed to get in the lounge by stating our flight number even without our boarding pass. The lounge is clean but small. It does offer free WiFi, power outlets, USB outlets and comfortable seating area. Each guest is offered a can of beer, and unlimited coffee and soft drinks, though there is no food offer. Overall it provides a safe and comfortable place to relax while you are waiting for...

For a priority pass lounge it's not great, but it opens 30 minutes before security at terminal 1 so it was convenient. Free beer on entry as others have said, I didn't get one but it looks like it's a can of Asahi, unsure if that changes from time to time.

It's just rows and rows of closely connected seats with cup holders. Very limited vending drinks, and a small pack of nuts (limited to 2 each) for food. Most priority pass lounges I've been to have proper meals as well as drinks, but I believe this is also a credit card lounge hence the offering.

WiFi seems great, download speed (tested) of around 75mbps at 17-20ms ping, great for downloading a few Netflix shows for the flight.

For free, it's fine. I...

Only drinks, you get one free asahi beer per person, coke or orange juice or water, or coffee/cappuccino type drinks. The seats aren't too terribly comfortable, and you're not allowed to bring in outside food or talk on the phone. There is also no bathroom inside. Only perks are they don't care if you stay for more than the usual 3 hours and it's a nice place to leave your luggage since if you're here you probably haven't checked your bags yet. The staff was nice and the place was very clean, it was just disappointing that there weren't more options. And you couldn't eat your own snacks...
