First, keep in mind that there are about 12 million people in what most people consider as Tokyo. This is not Lincoln, Nebraska, where I without fail I would see someone I knew everytime I left the house.
September 2004:
At Narita airport, after seeing a friend off I felt a tap on my shoulder while in line at McDonalds. I turned around to find Noriko, the JTB travel agent who came to Nebraska a few months earlier, looking as suprised as I was to see each other.
October 2004:

In a yamanote train car I met Nozomi as she exited at Ikebukuro staion. This was actually the content my first post ever.
November 2004:

On the joban platform at Matsudo station, Yoko and I recognized each other, the last time we met was at Senshu University in 2002.
December 2004:

Once again at Matsudo station, I met another Senshu student, Naho, who had come to Nebraska a few years ago.
Other Times-
I should have kept better track because I am confused with the dates. From here I will work backwards from last night.
Last night:

At Starbucks in Shunjuku’s Lumine department store I saw Tomoko Irie, a former teacher of Japanese at the University of Nebraska in 2001.
About two weeks ago:

While sitting at the same starbucks (where I meet my recently married friend Rie for english practice) Ayako, a former RA at the kokusai kenshu kan international dorm at Senshu University came to our table to say hi. I had not seen her since Senshu’s graduation in 2002.
About a month ago:
While waiting for Rie at the South exit of the Odakyu line, Aya’s sister Mayuko came up to me and said hi. The weird part was how it took my brain a second or two to recognize her and who she was. I know her well enough but it was the combination of the person and the place that threw me off .
This spring:
I met my friend Jun in Shinjuku by accident, but I don’t want to count this because we were both going to a nomikai that night anyway, but we did meet an hour earlier than we were supposed to, and in an entirely different location than had been set before.
I met Aya in the Nikon Salon by chance in February.
In Shibuya after seeing Arakimentari I soon came across a Mayu, one of Mistugu Onishi’s students whom I met at her class final exhibition(That is her on the far left). I took her and her friend’s picture as they took mine (she is the second in from the left).
So that is about one person a month that I meet by chance. Or fate.
One other thing though– Before Onishi Mitsugu’s slide talk in Shinjuku 2 months ago or so, I had a chance to meet his wife and daughter (「大西先生、二人の娘がいったっけ」と私が言った). I went back a few days later to see the show again and his wife was there as well. We got to talkin’ and she said that her daughter’s friend (who was also there at the slideshow) had seen me before. She then asked if I had ever taken photographs at Waseda University- and I have. In December we took interested students from our 3rd year jr high class on a campus tour, and I did indeed snap a few rolls of film. Whats more, this daughter’s friend’s american boyfriend said that based on her description of me, he remembered seeing me sometimes at Matsudo station, despite the fact that we had never met. And there is no way that that friend who saw me at Waseda knew that I live in Matsudo.
So, “random” chance meetings are now expected, about once a month.
someone is going to find me
