Kita-Kamakura Station.
An alternative is to take the private Odakyu line from Shinjuku to Fujisawa, then change onto the rattling old Enoden 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 Shinjuku(Other Odakyu,Seibu and Sotetsu all stations) and unlimited use of the Enoden line for one day
