If you are planning to visit Tokyo and from there visit some other areas of Japan, you might be asked to chose between two possible airports: Narita and Haneda. Narita is the new international airport and it seems to be exceptionally designed. I have a couple of friends that flew to Narita and they all said the same: great airport but it is 40 minutes by train from the City.
By chance we had to fly to Haneda, the former principal airport and now the reference point for domestic flights and some selected international ones. The airport is extraordinarily close to the city that could be reached in 10 minutes with the available monorail, which links the airport with Hamamatsucho Station where the Yamamote Line (a circular JR line that connects almost all Tokyo neighborhoods), other JR Lines and subways are easily reachable.
We flew from Dubai to Tokyo with Emirates and landed in Haneda whose arrival terminal is very minimal but efficient. Indeed, we landed, passed through immigration and collected our baggage in less than 20 minutes. A high speed WiF is also available, which I successfully used to call home with Skype without any trouble.
The Airport staff are very polite and available to offer information and indication and almost all of them speak English in a suitable way (rare thing in Japan).
The departure terminal is al-right with a check-in process efficient even though not really as fast as expected. Compared to Emirates Terminal 3 in Dubai, Haneda seems really small, however, it offers enough souvenirs shops and restaurants to spend easily 1 or 2 hours while waiting for boarding. just note that some shops close at 10 p.m., hence you might miss that nice bag you wanted to buy “after a quick bite” as we did.
The monorail is perfectly integrated in the airport and is easy to reach. Note that since it is operated by JR you can use your JR Pass to access it. However, if you have bought a JR Exchange Order in advance and need to exchange it with the real Pass, remember that the JR office in Haneda Airport closes at 18.30 Tokyo time and you will be asked to pay for the monorail ride if you land after that time.
The use of the JR Pass can seem quite complicated and its high cost can discourage from buying it but it is a valuable tool if you plan to visit more than Tokyo. This detailed JR Pass guide shows you hot it works.
