Why Do Japanese Kids Buy Bugs at Department Stores? (The Beetle Obsession)

Last updated: March 20, 2026

Pets, Not Pests
In the US, if you see a giant black bug, you probably scream and grab a shoe. Bugs are not popular pets. But in Japan, big, shiny, hard-shelled bugs are the ultimate summer obsession for children. They are considered cool, like tiny armored superheroes.

The Kings of the Forest
The two most popular superstars are “Kabutomushi” (Rhinoceros Beetles) with their giant horns, and “Kuwagata” (Stag Beetles) with their sharp pincers. In the countryside, kids wake up at 5:00 AM, go into the dark forest, and put honey on tree trunks to catch them in the wild.

The Luxury Bug Boutiques
But what if you live in a concrete jungle like Tokyo? You buy them! During summer, pet shops and even high-end department stores set up “Beetle Corners.” A standard beetle might cost $10, but rare or giant species can easily cost hundreds, or even thousands of dollars. They are luxury items!

The Plastic Pet Life
Once a kid gets a beetle, they put it in a plastic “Bug Cage” (Mushi-kago) filled with special soil and wood. Supermarkets even sell special “Beetle Jelly” cups to feed them. Watching the beetle eat sweet jelly is a core summer memory for millions of Japanese people.

A Respect for Nature
This bug obsession teaches children how to care for living things. Because these beetles usually only live for one summer, it is also a child’s first lesson about the fleeting, precious nature of life.
