Haneda is the most convenient airport if you plan to visit Japan… or Tokyo at least. Narita is bigger, has more flights to Europe or Northern America, but is also quite far from Tokyo. You’ll need a good train ride to reach the city center, whereas from Haneda it only takes a short ride on the Monorail. Moreover the airport is smaller, beautifully arranged… in short: much easier.
