Kamakura is a very popular day trip from Tokyo for locals and tourists alike, and there are plenty of transportation options.
By train
The fastest way to Kamakura Station is by JR Yokosuka Line from Tokyo Station one hour, ¥890 and Yokohama 25 minutes, ¥330. The JR Kamakura-Enoshima Pass gets you a round trip in this area with unlimited use of JR, Enoden and Shonan Monorail lines. You can buy the ticket at Ofuna, Fujisawa, Kamakura or Kita-Kamakura Station.
An alternative is to take the private Odakyu line from Shinjuku to Fujisawa, then change onto the rattling old Enoden æ±ãé» half-train/half-streetcar line that terminates in Kamakura. The longer about 90-minute travel time is compensated for by views of Enoshima island and the Shonan coast. The Enoshima-Kamakura Free Pass will get you a roundtrip from ShinjukuOther Odakyu,Seibu and Sotetsu all stations and unlimited use of the Enoden line for one day.
By plane
From Narita Airport, the fastest and most expensive way to reach Kamakura is to take the Narita Express in the direction of Yokohama or Ofuna, and then change to the JR Yokosuka line for the run to Kamakura. This takes approximately 2 hours and costs ¥4500, but if you use JR's Suica & N'EX combination ticket for foreigners, the fare is reduced to ¥3500. It may be more convenient to change to the Yokosuka Line at intermediate stations, where it is as simple as a same-platform or cross-platform transfer: If the Narita Express terminates at Yokohama, change at Musashi-Kosugi; if it terminates at Ofuna, change at Totsuka.
Regular JR commuter trains depart Narita Airport once per hour: some trains offer one-seat rides to Kamakura station, or else change at wherever the train terminates to the next train bound for Zushi, Yokosuka or Kurihama About 2 1/2 hours, ¥2210. These trains offer a ¥950 Green Car seating upgrade; Green cars feature more comfortable seats and a drink and snack service.
From Haneda Airport, take any Keikyu Line Airport Express ã¨ã¢ãã¼ãæ¥è¡ train bound for Shin-Zushi or Kanazawa-Bunko, and change at Yokohama station for the JR Yokosuka line One hour, ¥800.
If you plan on staying at a Ryokan it may be a good idea, unless your plane lands in the morning, to spend your first evening in Tokyo or Yokohama, or else you might miss out on and be charged for dinner at the ryokan, or worse, you may be locked out of and be charged for your room at the ryokan's curfew time, if there is one. If you plan to stay at a budget accomodation, check to see whether or not it has a curfew time.
