The answer is - the same way over 1 million people travel every day - through the Shinjuku rail station! I was on my own tonight making my way to the busiest rail station in the world, experiencing commuter culture of literally being shoved tighter and tighter in the train car at each stop so more people could get on in order to get to Shinjuku for transfer to another train. I haven't had much trouble navigating the underground system here, but Shinjuku is another world. After arriving at the station and much walking and wandering, I finally did find the connection I needed but with only a few minutes before a symphony performance.
Bill had to leave Japan in order to re-enter the US before his 90 days were up, so instead of going all the way back to San Francisco he left tonight for Kauai to stay with Andrew and Shawnie before he returns over the weekend. So I met Bill's boss Philip and another gentleman from Bill's office at the symphony - it was worth it - another great Mahler Second. The three of us went out after the symphony for a typical Japanese dinner of Yakitori - skewered grilled meats- had some sashimi and beer too!
Philip and I shared a ride home though - no Metro tonight!
