According to Rocketnews24, Japanese chemical company LION has provided a website called Gokiten ("Cockroach Weather") that forecasts the possibility of seeing cockroaches in your favourite region of Japan. Users can submit their own cockroach sightings to the website, where presumably the data is mined so that bug-killing products can be marketed to areas with high infestation.
At the time of writing, Sapporo is sitting pretty at a Cockroach Index of 2, compared to the unwashed masses of the southern islands who are living knee-deep in their own filth with Cockroach Indices of 4.
