Unlimited Shinkansen rides offer great value for money, allowing you to go skiing in Karuizawa, Echigo-Yuzawa, Mt. Fuji, and many other destinations in Nikko – all at a very reasonable price.
I came from Hiroshima to visit my cousin in Tokyo, and since I had the opportunity, I invited my cousin to extend our trip to visit the Tomioka Silk Mill, which I had been curious about. The Joshin Electric Railway train we took had a retro feel, and the town of Tomioka, where we arrived, also had a nice atmosphere. After enjoying the local specialty, okkirikomi udon, we finally entered the mill. Long brick buildings stretched out before us, conveying the atmosphere of the Meiji era. I was overwhelmed by the magnificent facilities inside the cocoon storage and reeling rooms. Thanks to the staff who gave us detailed explanations, I learned a lot. The wooden buildings scattered around, such as the company housing and the women's workers' dormitory, also evoke the past and have a lot of character. I was also able to receive a luxurious booklet with my World Heritage certification, which made me very happy. The people of Tomioka were also very kind. I'm so glad I came.
The children were so happy. They weren't able to try horseback riding yet, so we'd like to come back again.
