Tokyoites continued sweltering in the intense heat wave on Sept. 18 as a high temperature record dating more than 80 years fell. 

The mercury hit 35.1 degrees in the capital on Sept. 18, which marked the latest date that the temperature exceeded 35 degrees since observations began in 1875, according to the Japan Meteorological Agency.

The previous record in Tokyo was set on Sept. 12, 1942.

The nation's record for the latest date was set on Oct. 9, 2013, in Itoigawa, Niigata Prefecture.

In Tokyo, the temperature failed to dip substantially during the night and rose from the early morning of Sept. 18.

It is expected to exceed 30 degrees on both Sept. 19 and 20. The heat wave is expected to gradually subside from Sept. 21 onward due to rainfall caused by a front.
