Our plan for visiting Yokohama was to go in the afternoon after returning from our morning trip to Kamakura. We took the train from Hase Station to Kamakura Station and then from Kamakura Station to Sakuragicho Station, which is in the Minato Mirai 21 district.

For those traveling from Ikebukuro or Shinjuku, take the train to Yokohama Station and then transfer to Sakuragicho Station.

Walking out of the station, there was a performance to raise money for disaster relief (donated 1,000 yen).

Walk straight towards the Sky Garden Observatory building, which you can see the escalator going up.

Opening hours are 10:00 AM - 9:00 PM (Saturdays open until 10:00 PM). Entry is 30 minutes before closing time. Admission fee is 1,000 yen.

The Shinyokohama Raumen Museum is a unique museum dedicated to ramen, one of Japan's most beloved noodle dishes.

The second floor is designed to resemble the streets and houses of the Shitamachi district, Tokyo's old town, around 1958.

The first floor of the museum is dedicated to the history of ramen in Japan.

You can choose from a variety of ramen shops. Once you have chosen a shop, go to the shop and choose the ramen you want. Insert coins to pay, receive a coupon and give it to the shop staff. Keep one part with you so that your order can be served correctly.

Shop number 3 looked delicious but the queue was long, so I went to shop number 6 instead.
