Today was a day off. Instead of sitting around the house, I managed to get out of bed in the morning and went to Yokohama.
I took the Tokaido line to Yokohama, which takes about 90 minutes from Numazu. When I looked up my train schedule, I found that I could have also taken the Shinkansen from Mishima to Shin Yokohama and finished with a subway connection to Yokohama station. This would have only saved me about 20 minutes overall, and would have cost twice as much.
I did some shopping around Minato Mirai, and ended up buying a figurative ton of books. I also saw a really cool street performer who was busking in front of Landmark Tower. He had a 10 minute show where he was juggling increasingly more dangerous items. I have seen street performers before, but this guy was really good. When it came time to pass the hat at the end of the performance, he must have easily made 30,000-50,000 yen (about $300-$500)
After spending a bunch of time in Numazu and Mishima, I had forgotten how big and exciting Yokohama was. It am happy that I still live so close.
