Case: Shinjuku-Shibuya 1-2 hours for round trip There are many sight-seeing bus tour courses in Tokyo and its suburbs , taking from 2-3 hours up to one full day. However , it is not the only way! Another enjoyable ,easy and inexpensive way is to take public buses at your convenience, take a walk or do the sights as you like at various stops in various areas ! The merits are : 1 You do not need reservation. 2 Public buses cover most main areas in the city. 3 Bus terminals are mostly connected to different bus lines, subways or railways. 4 As most bus runs every 5-10 minutes , you can get off at any stop and get on the bus that comes at any time you like. 4 Last but not least, public bus fee is only 210 yen for one trip! Here’s one example, which is recommendable if you are staying in Shinjuku or Shibuya area or have easy access to them The bus id is [Keio Bus (Route No.51)] It’s terminals and major stops are as follows (You can take this bus at each terminal and any stop out of those. The interval is every 5-10 minutes during 07:00 am to 22:00 pm) Shinjuku Station -West Exit( 新宿駅西口) Forest Town(フォレストタウン) Yoyogi 3-Chome (代々木三丁目) Sangubashi Station ( 参宮橋駅) Yoyogi Park ( 代々木公園) NHK Broadcasting Center ( 放送センター) Shibuya Station (渋谷駅) Any stop of this Keio Bus (Route No.51) is worthy to get off and have a walk to view the typical urban residential areas of Tokyo, but, one recommendation is to get off at Yoyogi Park stop and see around as presumably it is one of the most gorgeous parks in Tokyo.
