There were easily about a five hundred to a thousand people dressed up. There were many more Japanese people taking part than I would have expected, but the crowd was predominantly geijin. JR knows when we do it and were prepared. They had an area all corded off for us, and extra staff. When our train pulled in they had cleared three cars for the be-costumed. The doors opened and everyone rushed in. A few poor Japanese souls were caught in the wake and road in what must have been the most horrible train experience for them ever. I can say, because I am trained as a scientist and I was dressed as one, that we easily violated the conservation laws of mass and energy during the ride. I know this because three cars were not enough to contain us all, and I most certainly was existing at the same place at the same time with other people. It was horrible. I imagine as the night goes on the riders break the three car rule and commandeer the whole train, but it was agonizing at first. I was next to some poor Japanese guy that wanted off, he managed to work his way to the door only to have the doors on the other side of the train open. By the second or third stop I managed to work my way to a door and got off. I did not scramble to get back on. Like Drag Ball at my fair Oberlin, it was enough for me to say, “Yeah, I was there.” I do not require the event to last long.
I have ridden the train during rush hour, so I know what being squashed is like. This was infinitely worse and infinitely more squashed-ed. I found it not very fun. But I think it probably hurt that I do not drink. As I watched random people pouring random alcohol into still further random people’s mouths, I realized, “this is probably more fun when imbibing copious amounts of alcohol”. But now I can say, “I did the Osaka Halloween Loop Line Party!” It is just another cultural experience on my resume of worldly things.
