I am a British national living in Japan. On the same day, both my wife and I had chance encounters with friends travelling outside their home countries.
I was in a ramen bar in Shibuya, Tokyo, when my cousin from England walked in and, without realising I was there, sat down next to me. Although I knew he travels to Japan from time-to-time, I did not know he was in the country and had not contacted him recently. I eat in Shibuya perhaps once in a fortnight. He, perhaps a couple of times a year.
