Japanese efficiency and really decent cost! Flew RT Narita-Sapporo Sept 2014 and loved it. English website that was understandable. Every employee super nice and since I was the only non-Japanese on the flight, did all the announcements in English as well as Japanese. No Frills and they mean it.
Check the real ticket price: When you search for flights, some airlines show you the ticket price without taxes (like fuel fee, airport taxes, government taxes). Before choosing a flight, check the full price (inclusive of all taxes), which has to be displayed on the page where you are requested to enter your card details.
