My day trip to Nagoya went well, but man! there was an icy wind blowing in the city today. I was so glad I had packed my woolen skull cap.
Here’s the http://rmrestaurant.co.uk/contact-us/ Tōkaidō Shinkansen (bullet train line) that runs from Tokyo to Nagoya, that I took. It continues its run from Nagoya on to Osaka. A more direct line to Nagoya will open in 2027, and be extended to Osaka by 2045*.
