「JR立川駅」まで : JR中央線「東京駅」から快速で約50分，「新宿駅」から快速で約40分
Most international fights to Tokyo arrive at Narita Airport (http://www.narita-airport.jp/en), but there has recently been an increase in service to Haneda Airport (http://www.haneda-airport.jp/en). NINJAL is located in the city of Tachikawa, which is a long distance from either airport.
There are two options for getting from Narita Airport to Tachikawa.
If you have purchased a Japan Rail Pass so that you can travel around by train before or after the conference, you can exchange your voucher for the actual pass at the JR East (East Japan Railway Company) station in the airport and take the Narita Express (http://www.jreast.co.jp/e/nex/narita.html).
There are two trains a day that will take you all the way to Tachikawa. They leave Narita Airport Terminal 1 at 19:46 and at 20:44. If you do not have a rail pass, this trip will cost 4,290 (JPY).
If you are not able to take one of these two trains, you will have to take the Narita Express from the airport to Shinjuku (http://www.jreast.co.jp/e/stations/e866.html). At Shinjuku, it will be necessary to transfer to an outbound Chuo Line commuter train. All outbound trains stop at Tachikawa. If you do not have a rail pass, this trip will cost 3,660 (JPY).
Please note: The Chuo Line is one of the most heavily used train lines in Japan, and the outbound trains are extremely crowded from mid afternoon until late at night. It will take at least 25 minutes to get from Shinjuku to Tachikawa, and you are very unlikely to find a seat. Also, it can be quite a challenge just to get on and off the train if you have a suitcase.
For most people, especially those with luggage, the Airport Limousine bus (http://www.limousinebus.co.jp/en/platform_searches/index/2/101#reserve) is a better option. The ticket counters are located just outside the exits from Customs and Immigration. There are 9 trips a day to Tachikawa, and the fare is 3,600 (JPY). The last departure each day is at 20:20-20:30 (depending on which of the three airport stops you board at). The trip typically takes about 2.5 hours, but it varies considerably depending on trafic conditions. When you buy your ticket, the clerk will ask you where you want to get off. Choose either Tachikawa Station/Grand Hotel (the first stop) or Palace Hotel (the second stop), depending on where you are staying. Unless you are staying at the Palace Hotel, the first stop will probably be better, but be aware that it is actually quite a distance (about 300m) from Tachikawa Station.
There are two options for getting from Haneda Airport to Tachikawa.
Unless you are familiar with the Tokyo commuter train network and do not have much luggage, we do not recommend traveling from Haneda to Tachikawa by train. The easiest route is to take the Tokyo Monorail (http://www.tokyo-monorail.co.jp/english) from the airport to Hamatsu-cho, the JR East Yamanote Line or Keihin-Tohoku Line from Hamatsu-cho to Tokyo Station, and the JR East Chuo Line from Tokyo Station to Tachikawa.
The Airport Limousine bus (http://hnd-bus.com/route/haijima.html) is the recommended option. The airport ticket counter is located just outside the exit from Customs and Immigration. There are 20 trips a day to Tachikawa, and the fare is 1,550 (JPY). The last departure each day is at 23:35-23:50. The trip typically takes a little less than 2 hours, but it varies considerably depending on trafic conditions. When you buy your ticket, the clerk will ask you where you want to get off. Choose either Tachikawa Railway Station (the first stop) or Palace Hotel (the second stop), depending on where you are staying. Unless you are staying at the Palace Hotel, the first stop will probably be better.
If this is your first trip to Japan, the area around a major railway station like Tachikawa may feel like a maze, especially if you arrive after dark. Your hotel’s website should include a map that will help you to find your way, but if you get lost, almost anyone you approach will try to help you. Try to speak English slowly and clearly (although you might be lucky enough to run into someone who is highly proficient). People who work in convenience stores (7-Eleven, Lawson, Family Mart, Sunkusu, etc.) usually know the area well. If necessary, you can ask for directions at the police box near the Krispy Kreme on the north side of Tachikawa Station (ground level) or at the information counter inside Tachikawa Station (located upstairs near the ticket gates).
The National Institute for Japanese Language and Linguistics (NINJAL) is located about 1.5km north of Tachikawa Station. You can get from Tachikawa Station to NINJAL on foot, by bus, by monorail, or by taxi.
On a nice day, the easy 20-minute walk from Tachikawa Station to NINJAL is very pleasant. ( walking directions [ PDF | 888KB ] )
Buses run frequently between Tachikawa Station and NINJAL, and the ride takes about 5 minutes. There is a bus stop right in front of NINJAL. The bus is probably the best option on a rainy day, but it is not to easy to use if you do not know Japanese, so please follow the instructions provided. The fare is 200 (JPY).

The Tama Monorail stops both on the south side and on the north side of Tachikawa Station. The closest monorail station to NINJAL is Takamatsu, and the ride takes about 2 minutes from Tachikawa-kita (the Monorail station the north side of Tachikawa Station). However, it takes about 7 minutes to walk from Takamatsu station to NINJAL. Please follow the instructions provided. The fare is 100 (JPY). ( monorail directions [ PDF | 499KB ] )
There is a taxi stand on the north side of Tachikawa Station near the Starbucks on the ground level. The minimum fare of 730 (JPY) should be enough to get you from there to NINJAL. You can also catch a taxi on the south side of Tachikawa Station, but it will take quite a bit longer and cost more because the driver will have to take a circuitous route to get under the train tracks. A single taxi is big enough to carry 3 people comfortably, and it is usually possible squeeze in 4 people, with one passenger in the front seat. The driver pushes a button to automatically open and close the left rear door (where passengers normally get in and out), and passengers are not supposed to open or close this door themselves. Most drivers do not speak English, but they will understand if you say "Receipt, please." On the other hand, "NINJAL" will mean nothing to a taxi driver, so if you plan to take a taxi, you should print out the taxi directions provided so that you can show them to your driver.
