You can take the private Odakyu line from Shinjuku to Fujisawa 54 minutes via kaisoku-kyÅ«kÅã(å¿«éæ¥è¡ãor 66 minutes via kyÅ«kÅ æ¥è¡), then change onto the rattling old Enoden æ±ãé» half-train/half-streetcar line to Enoshima. The Enoshima-Kamakura Free Pass Â¥1,430 will get you a roundtrip from Shinjuku and unlimited use of the Enoden line for one day.
If you don't want to experience the vintage Enoden, you also have the option of taking the Odakyu all the way to Katase-Enoshima çç¬æ±ã島 station, which is the closest location to the main beaches and the island of Enoshima. There are not too many direct trains from Shinjuku; however, a connection at Sagami-Ono or Fujisawa is easy and convenient you walk about 10m to the other side of the platform.
For a small extra charge you can take the all-reserved limited express "Romance Car" train direct from Shinjuku to Katase-Enoshima. The service to Enoshima is called, appropriately, Enoshima ãã®ãã¾, with some weekday services from Shinjuku also known as Home Way ãã¼ã ã¦ã§ã¤. Be warned that many of these trains are coupled to services bound for Hakone, which split at Sagami-Ono. There are more Romance Car trains to and from Enoshima on weekends and holidays than there are on weekdays.
The one-way fare from Shinjuku to Katase-Enoshima on the Odakyu Line is ¥1210 for the Romance Car, and ¥610 for regular services. Users of the above-mentioned free pass can upgrade to the Romance Car for ¥600 each way.
If you have a Japan Rail Pass, you can reach Fujisawa by taking a Tokaido Line from Tokyo about 50 minutes or a Shonan-Shinjuku line train from Shinjuku about 50 minutes at no charge, then pay the fee for the Enoden. A better, faster and more exciting way is to take the Tokaido or Shonan Shinjuku Line and change in Ofuna (大è¹ï¼to the Shonan Monorailãï¼æ¹åã¢ãã¬ã¼ã«ï¼, one of the few hanging monorails, that will take you directly to Enoshimaï¼æ¹åæ±ã島ï¼in about 20 min. They don't accept Suica/Pasmo, so you have to buy a ticket, ¥350 each way.
JR East offers the Enoshima-Kamakura Excursion Ticket, (http://www.jreast.co.jp/e...) which allows unlimited rides in the Kamakura/Enoshima area on JR, Enoshima Electric Railway and the Shonan Monorail. The pass lasts for one day and costs ¥680.
