Tokyo Narita (NRT)
Narita is the largest international airport in Japan serving both as an arrival and departure airport as well as a hub between Asia and North America. Domestic flights are limited mainly to connecting flights. The airport handles more than 35 million passengers annually with 2 terminals and 2 runways.
The airport had a eventful construction period as farmers protested their eviction which led to riots killing several. The airport opened with riot police in guard towers and document and baggage checks for those entering airport grounds. While the situation has calmed down passengers arriving at the airport are still subject to a document check and one of the 2 runways has not been extended to its full length.
As every airport in Japan, Narita offers spotting decks on both terminals. On terminal 2 (JAL) there are actually 2 decks, both enclosed by a high fence with limited photography holes. Terminal 1 offers a single, larger visitor deck which looks out over the runway directly. Photography at both is fine, but be aware that you might get a short visit from the police. They are very friendly and just want to get your information noted down, you won't be bothered in any other way. There are several other spotting locations around the perimeter that supposedly give better views. Due to time constraints we didn't visit them.


Tokyo Haneda (HND)
As Asia's busiest and the 4th busiest airport in the world Haneda mainly serves domestic services in Japan. The airport annually processes around 67 million passengers through 3 terminals. 'Big Bird', as terminal one is known is home to JAL, Japan Transocean Air and Skymark. ANA, Skynet Asia Airways and Air Do operate from terminal 2, while StarFlyer operates from both. Limited international flights are operated from the international terminal by ANA, Asiana, China Eastern, JAL, Korean Air and Shanghai Airlines.
By far the largest carriers are JAL and ANA which operate anything from a 56 seat Dash 8-Q300 to a 569 seat 747-400D. Being the main domestic air transport hub, widebodies can be seen in great numbers here, with narrowbodies in the distinct minority. Especially the 747-400D are a rare aircraft not seen outside Japan and ANA has painted 2 in colorful Pokémon colors, very popular with children and Japanese parents alike.
Haneda boosts 3 spotting decks, 2 on Terminal 1 (JAL) and 1 large deck on terminal 2 (ANA). All are covered by a 3m/10ft+ high fence which has holes in them. However, these holes are targeted at the Japanese so they are pretty low for westerners. Night photography can very well be done with the decks being open until 10pm and excellent lighting conditions at the gate and near the pushback.
