Night stalkers! Shell carpets! Creepy bugs! Is the city safe? With the help of viewers, the Tokyo Wildlife Survey Team is on a mission to investigate interesting phenomena in summer in Japan's capital. The adventure begins at dusk at a river running through the heart of the city; a residential area near a tidal flat; even the country's iconic cherry blossom trees, with insect "shells" on the trunks! And so many small holes all over the ground! There's plenty of wildlife hiding in plain sight!
