On the morning of Oct. 16, central Tokyo recorded a low of 12.4 degrees, about 2 degrees below average for this time of year.
Other cities experiencing colder than normal temperatures were: Sapporo with 4.2 degrees, Sendai with 8.6, Niigata with 10, Yokohama with 13, Shizuoka with 14.9, Osaka with 14.7 and Kobe with 15.2.
That doesn’t sound all that cold. However, the Japan Meteorological Agency said that current conditions are equivalent to the early December chill.
