This is the air quality page for Tokyo on accuweather.com
https://www.accuweather.com/en/jp/tokyo/226396/air-quality-i...
Clicking on the Learn more from Plume Labs takes you to the air quality data source.
https://air.plumelabs.com/air-quality-in-Tokyo-7Lj5
You can see graphs with the tabs named Live, Week, Month, Year. We can check past data there. The weekly graph shows 72 AQI on May 18th. The yearly graph shows the annual average of 39 AQI.
Can you confirm that you see the same data?

Is that the 24 hour average? I literally have photos on my phone from Thursday morning showing AQI 142 and a Tokyo map soaked in pink and red. I snapped them to send to my wife, who was planning to take the kids to the park. It was also obvious to anyone with a functioning noise on their face. Not sure what to tell you.

It's the value taken at Thu 18 May 01:50PM. It's an interactive chart. The weekly version shows readings every couple minutes.
According to [1], yesterday's peak of PM2.5 (not the 24 hour average) in Tokyo was at 22 µg/m3, whereas according to [2], the WHO's (extremely strict) limit for 24 hour average is set at 15 22 µg/m3. Where did you get your data from?
