You'll want to tell someone! A three-choice trivia quiz about Doraemon

The Earth is a demolition bomb.

Doraemon hates mice. When a mouse appeared in the house, he tried to get rid of it, but he lost his cool and pulled out the “Earth-Destroying Bomb” from his four-dimensional pocket—a bomb powerful enough to blow up the planet. However, Nobita lied, saying, “The mouse already ran away,” and managed to defuse the situation. It really shows just how much Doraemon hates mice.

Doraemon’s weight is set at 129.3 kilograms, and it’s said to be modeled after the average height of a fourth-grade elementary school student.

129.3 horsepower

According to official sources, Doraemon’s power is said to be 129.3 horsepower. The number 129.3 is used in many aspects, such as Doraemon’s height being 129.3 cm and his weight 129.3 kg. It also symbolizes his strength as a robot. The origin of the number is related to Doraemon’s birthday, September 3, 2112, and it is cherished as a very important number in Doraemon’s world.

22nd century

Doraemon is a robot who came from the future in the 22nd century. In terms of the Gregorian calendar, the 22nd century refers to the years 2101 to 2200, and the setting is that Doraemon was born in 2112 at the “Matsushiba Robot Factory.” Although there were scenes in the early setup where it was described as the 21st century, it was later fixed as the 22nd century—partly to align with “129.3.” That change is also an interesting point when discussing Doraemon.

In the closet

Doraemon’s usual sleeping spot is inside the closet in Nobita’s room. This is a familiar scene in the original manga and the anime, beloved by many fans. They use the closet like a bunk bed: Doraemon sleeps on the upper level, while the lower level is for storing belongings. It’s also memorable how they make use of the small space like a secret base.
