Immigration was quite slow and crowded. It actually took me 40 minutes to clear immigration and customs.
Since I did not have any checked in luggage I did not have to wait for it, but I was just in time to get the last bus for the Terminal 2 airport hotel : Excel Tokyu hotel.
This hotel is located within the domestic terminal 2, from where mostly ANA operates.
The hotel did the job for the price paid (120 Euros booked via hotels.com) and wifi was auite fast. The room in itself was quite small with 2 single beds. Since I was travelling alone with just carry on luggage it was fine, but if you travel with some additional luggage as a couple, it might be too small.
