It was a rainy day.
In the morning I went to MLIT and in the afternoon we went to the Tokyo Sky Tree. It was a part of the research visit, therefore we could visit many "Staff Only"places and we were escorted, though we paid yen 3090 to climb up to the top.
After finishing the visit and saying good-bye I happened to see two of them again and we went to have sweets.
There was a Japanese sweets shop where was selling warabi mochi (わらび餅), bracken skewered which I have never seen. There are many dumpling but I could not imagine warabi mochi using skewer because they are so soft. The original taste was sold out, and we ate maccha, green tea taste. It was good to try.
Here is a picture after the light up too.
