The January-2023 mean temperature data from the Japan Meteorological Agency (JMA) for Tokyo and its Hachijō-jima island in the Pacific have just been released.

Not surprisingly honest institutes that don’t rewrite history like the the JMA show temperature trends that are not unusual.

First we look at the JMA temperature data and linear trend since 1985 for the megacity of Tokyo:

Mid winter (January) in Tokyo has been cooling over the past 38 years! No warming – winter seems to be getting harsher.

Hachijō-jima

Next we look at the mean January temperature of the Tokyo offshore island of Hachijō-jima, going back to 1945. Due to its rural location, the urban heat island effects allow cleaner temperature readings than what we find in the middle of Tokyo’s sea of concrete, asphalt, steel and waste heat from heating and automobiles:

Hachijō-jima island is located 287 kilometers south of Tokyo, in the Pacific Ocean. Here as well the January mean temperature trend hasn’t risen in nearly 80 years. It too has cooled since 1985, linear trend.
