Central Japan Internatinal Airport Chubu Nagoya
This airport saved our lives. After the last day of exploring Tokyo, we took the Shinkansen to Nagoya, and took yet another train to the airport. We arrived sweaty, desperately tired, hungry, and totally not ready to wait 4 hours before an 8 hour flight. BUT, we found a sento in the airport, and instead of sitting in sharply designed aluminium chair for 4 hours, we sat in a variety of hot baths, cold baths, saunas, and got totally squeaky clean. Rescued!
"Savour the atmosphere of the airport"
And I should also add from the site:
"As well as brimming with the atmosphere of the aircraft, in the distance you can enjoy the picturesque scenery of Ise Bay."
