The Yamazaki family arrives at Akikawa Station and heads into a cicada-filled forest to carry out a mission assigned by Headquarters Chief Tamura. With bug nets in hand, they excitedly begin their search, spotting a praying mantis and later a stag beetle—only to be startled by a sudden “black shadow.” After the scare, they finally find a rhinoceros beetle and celebrate like kids again. Having achieved their real goal of bonding, they spend the rest of the day playing in the river and enjoying a barbecue. Once fully relaxed, the general producer takes on the role of MC, and the group sets aside their characters to enjoy a “real summer vacation” as fellow actors. In the laid-back atmosphere, they share candid memories of joining Unification of Japan (Nihon Touitsu), their fellow Yamazaki members, and their feelings toward the director.
