Kabutomushi

The Japanese rhinoceros beetle, Japanese horned beetle, or kabutomushi (カブトムシ^?), Allomyrina dichotoma, is a species of rhinoceros beetle found in Japan, Korea, Taiwan and China.

Japanese rhinoceros beetles are very popular in anime, tokusatsu, advertisements, televisions, and films in Japan.  The Monster Rancher video game series also includes a giant rhinoceros beetle called Beaclon.

It is sold as a pet in department stores in many countries of Asia (in Japan, even in vending machines), where it is also frequently depicted in popular media as a common cartoon character for various uses, for example much as cartoon bears, lions, or alligators are seen in advertisements and product labels in the United States.

Many children in Japan buy or catch these bugs and breed them. Male and female insects will cost about 500 to 1000 yen (approximately five to ten US dollars).

Male beetles normally die in the fall after mating many times, whereas female beetles normally die after laying eggs. 

Touching the Japanese rhinoceros beetle too suddenly, even after it has metamorphosed, may cause the beetle to die of shock.
