Tip: Book your hotel and bus tickets early.  In places like Kawaguchiko, especially going back to Tokyo, all the buses were packed and you can't buy tickets on the day itself. So better reserve and buy the tickets early. You can still change it (one-time change only) if needed.  Lake Kawaguchiko Express Bus from Shinjuku Express Terminal to Kawaguchiko Station  Price: 2200 Yen (one-way) Durationg: ~2 Hrs Kusatsu Onsen Express Bus from Shinjuku Express Terminal to Kustatsu Onsen Bus Terminal  Price: 4000 Yen (one-way), if earlier you can buy 3100 Yen Duration: ~4 hrs Nikko Direct Odoriko Train from Shinjuku  Only one train per day Leaves 9.39 AM arrviving 11.35 from Shinjuku Leaves Tobu-Nikko Station at 4.39 PM, arriving 6.35 PM Kawazu Direct Train from Tokyo Station to Kawazu Duration: ~2.5 Hours
