Haneda Airport International Passenger Terminal Showeroom

Every modern, big/​major city airport should have a shower room service for passengers (yes, you pay to be able to shower). The lack of a shower room at an airport such as LAX is appalling.
I recently traveled out of Haneda airport for a flight from Japan to Los Angeles. As most travelers and tourist know, you need to check out of a hotel by 1100am or at the latest 100pm. What happens when you need to check out of a hotel at 1100am but your flight isn’t till 2300hrs 2400hrs that night? Yeah… as a tourist you leave the luggage at your hotel and you go out for some more sight seeing of course!
Fast forward to getting to Haneda airport that evening to check in after checking out of my hotel at 1100am and doing tons more sight seeing. You’re dirty and sweaty from the last bit of sight seeing you can get in. Yet you’re faced with a 10-​hour flight home. No one wants to travel on a long-​haul flight without a nice shower before you travel. That’s when the shower room service comes into play. The Haneda paid shower room was a life saver!
The Haneda airport shower room charges about $ 10 for 30 minutes which includes the use of their small shower with shampoo, conditioner, liquid soap and a sink. That’s all you need as a traveler. The room is big enough to accommodate 1 person and a luggage. The room is single use, no sharing rooms! The toilet is separate as well. I would have paid any amount just to shower before my flight. It was a life saver! The fees also came with one free drink from the concession stand right outside the rooms. The cashier was super nice and accommodating, there was also a room with small couches so the person can repack their luggage.
The shower rooms are located on the arrivals level of the International terminal right outside the Customs area (in the public area).
