The annual schedule for appropriate dates to get inebriated in a park has been released by Japan’s Meteorological Agency.

Most parks in the Tokyo area are predicted to be full of people engaging in party like behaviour, but only within a two-meter radius of their group’s carefully laid out blue tarpaulins.

“We’re looking for intoxicated people to start appearing in parks around Tokyo towards the latter third of March,” said Mayumi Kuroda, a spokesperson for Japan’s metrological agency.

The national meteorological agency has warned park-goers to observe the correct getting-drunk-in-a-park dates or they will be slightly frowned upon by the greater community.
