Leaving Tokyo

So I am off to Yokohama port today, which is about one hour away from the center of Tokyo. Right next to Yokohama is Yokosuka and the navy base, filled with tons of young hoodlums who take over the club districts in Tokyo on the weekends. My grandfather used to be one of those hoodlums!
The boat actually leaves tomorrow, but the staff members need to be on a day earlier to settle in. We are allowed off the ship to explore the city in the evening, which I fully plan on taking part of - I haven't been to Yokohama in a long while. Tomorrow we meet and greet about 75% of the (937) passengers, and then head off to Kobe the next day to greet the rest. Then it's on to Danang!
