The article reports an unusual phenomenon taking place in Japan, where there's a surge in the population of "Drop Seals" or "Droppy" migrating from the islands to the mainland, a movement peculiarly termed as "reverse migration". The reason for this unexpected migration is still under investigation by environmental habitation experts. Nevertheless, the rising number of these aquatic creatures in urban areas has sparked both concern and interest among the locals.

In Japan, harmony between humans and nature is a deeply entrenched societal value. This unusual migration event raises many concerns, particularly regarding the maintenance of ecological balance and the potential for human-wildlife conflict. It has also sparked curiosity among the public. Current discussions are centered on creating strategies to coexist with these seals and understanding the possible environmental factors triggering such odd behavioral changes.

In the US or EU, unusual wildlife migrations would similarly elicit both awe and concern. Governments typically involve environmental experts to investigate such anomalies and devise appropriate response strategies. Public awareness campaigns are launched to manage any potential human-wildlife conflict and to support conservation efforts.
