Tokyo to Yokohama is not as far away as I imagined. The Shinkansen is the least recommended one. The Yokohama Station of the Shinkansen is called Shin-Yokohama. After that, it is necessary to take a bus to get to the real Yokohama. From Tokyo, you can take JR, or Tokyu Toyoko Line Ikebukuro, Shinjuku, Shibuya can take the Shonan Shinjuku Line to Yokohama, Tokyo, and Shinagawa can take the Tokaido Line to the Yokohama Line. The one-way fare is around 500 yen.
