These three days are extremely unusual spring weather in Tokyo area. Some days are hot like mid summer and other days are chilly and rainy like late winter. Tokyo weather report agency reports this kind of cold May weather goes back to the record of the years of 1993 and 2008. Those two years have a common feature in Japan: the year of the beginning of recession. Climate often has a great impact on economy. especially on consumer's attitude for daily consumption. I experienced those two recessions here in Japan. I'm afraid that another one is creeping here.
