While walking in front of the Raporte North Building by JR Ashiya Station, I found a sign explaining a mysterious system.

…???
I mean… suddenly being told “System Overview” is a bit much…(I feel like I’ve seen a diagram like this in some kind of gag manga.)

Looking more closely, it seems to be a diagram showing how air is exhausted from the underground parking lot.
So basically, “We purify dirty air by passing it through the soil in the flower beds!”… Is that what it means!?

So does that mean the flower beds behind this sign are purifying the air?
Then…

Places around here,

and around here,

might actually be where purified air is coming out from? I had no idea!

The flower beds in front of the Raporte North Building may actually be working pretty hard. Thanks for keeping the air clean!
Here’s the map location↓
Address-wise, it’s around 11-24 Oharacho, Ashiya City, Hyogo Prefecture, in front of Futatsuka Pharmacy Ashiya Ekimae inside the Raporte North Building.
