In the morning, jump on a train and make the one-hour journey from Tokyo to coastal Kamakura. Kamakura once served as the political center for Japan from the 12th to the 14th century. Now it's a great destination offering a variety of experiences - munch street food, take a hike in the mountains,or simply enjoy a walk on the beach. Get acquainted with the area with a ride the Enoden Train Line, which features heavily in Japan's wildly-popular cultural exports of Manga and Anime and shuttles commuters from Kamakura and Fujisawa. You can catch it every 12 minutes between 5 am and midnight, and the round trip takes about an hour.
Even if you're not into animation, the electric rail line travels along the coast at a gentle pace, making it a great way to see some sights. Then, stretch your legs on the Daibutso Trail (approx. 3 hrs), which takes walkers over a partially paved track through lovely green gardens, past the Zeniarai Benten Shrine and finishes at the famous Buddha statue. In your free time, maybe get your shopping on at Komachi Dori Street, a 360-metre-long stretch of food, souvenirs, clothes and drinks.
