Actor Teruyuki Kagawa (58) updated his X (former Twitter) account on the 21st, reporting that he was teaching a one-year-old boy how to distinguish between male and female rhinoceros beetle larvae.

The photo posted included "Producer Kagawa giving a lengthy lecture on how to tell the difference between males and females, to the dismay of a one-year-old who happened to be there," in which he is gently holding the boy, who is wearing a matching Mickey Mouse T-shirt, and explaining about the larvae.

Kagawa remarried in 2022 and announced the birth of a boy in the same year, leading to comments such as, "What a precious photo of the unveiling (tears)!", "This is the first time he's unveiled here," and "Special education." There were also comments eager for the return of NHK's insect program, such as, "Please bring back Mr. Mantis," "I hope Mr. Mantis returns," "I want to see Mr. Mantis," and "I want him to come back."

Many people noticed that Kagawa's hair had grown out, been tied up, and was turning gray, with comments such as "Silver hair suits him really well" and "He's stopped dyeing his gray hair."
