Temperatures dipped below 5 degrees in central Tokyo for the first time this season on Dec. 10, less than a week after various areas across Japan basked under record-setting heat.

A cold air front brought chilly temperatures to cities across the archipelago on Dec. 10.

A low of 4.7 degrees was recorded in Chiyoda Ward in central Tokyo as of 6:30 a.m.

Osaka registered 3.6 degrees and Nagoya recorded 1.4 degrees, both seasonal lows for the two cities.

The mercury plunged to a bone-numbing minus 22.3 degrees in Nakashibetsu, Hokkaido, the lowest temperature in Japan on Dec. 10, according to the Japan Meteorological Agency.

On Dec. 4, more than 350 of the agency’s 926 observation sites around the country experienced their hottest December day on record. The high that day in Chiyoda Ward was 23.4 degrees, and many people in the capital were seen wearing T-shirts.

But on Dec. 10, pedestrians in front of JR Shinbashi Station in neighboring Minato Ward were bundled up in scarfs and winter coats.

“It was warm last week, but today I pulled out my down jacket,” said Masakuni Yamazaki, 39, while waiting for a bus at the station.

The low pressure system generated in southern Kyushu will move north over the main island of Honshu, leading to rain in the Kanto region from the night of Dec. 11 and possible snow in mountainous areas, the agency said.
