Tokyo Monorail
The Tokyo Monorail that runs between Haneda Airport and Tokyo, with an average interval of only 4 minutes, can take you to Hamamatsucho Station in as little as 13 minutes, where a transfer to the JR Yamanote Line can be made.
You can enjoy the views while riding the monorail—it feels just like driving yourself.
MOL Sunflower (Tokyo area ↔ Hokkaido)
The "SUNFLOWER" operated by MOL Sunflower Ltd. is a ferry that allows you to travel between Tokyo and Hokkaido at a very economical price. A new ship which went into service in 2017 (the evening ferry) has luxurious suites and relaxing, Japanese style rooms.
This was my first trip and I was so happy! I'll never forget seeing the snow—it really felt like something out of a drama.
