Tokyo Station shines brightly with its new Japan Rail (JR) Travel Service Center(open 7:30am – 10:30 pm everyday: http://www.jreast.co.jp/e/customer_support/service_center_tokyo.html
Here, you can ask anything you want about Japan Railways trains. You can purchase a JR East travel pass (available only to foreigners) and exchange your “All Japan” rail pass voucher or “exchange order” (purchased only outside Japan) for the actual 7, 14, or 21-day rail pass. You will even find the service center convenient for holding and delivering luggage and for money exchange! Foreign-card friendly ATMs are open from 7:30 am to 10 pm. The Japan Rail passes are a big savings and so convenient, but note, because Japan’s sales tax will increase from 5% to 8% on April 1st, the rail pass price is going up April 1st. An “ordinary”: seven-day pass was 28,300 yen, but will increase to 29,110 yen ($288.20), 14-day pass was 45,100 yen, but will increase to 46,390 yen ($459.30), and a 21-day pass was 57,700 yen, but will increase to 59,350 yen ($587.60).
The Service Center also provides information on rail tour packages in areas around Japan from Tohoku to Kyushu and helps in planning independent itineraries, such as a spring cherry blossom viewing itinerary in Northeast Japan or a 1 ½ hour, 4 km, on-your-own hiking excursion with views of Mt. Fuji! The former tells you the best dates for maximum blossoms per area, and the latter is available from April 11-May 31. The Fuji region hike departs from Fuji Kyuko Station, where you can also get additional hiking information, a free English-map, and get a free gift.
