From Emojis to Edible Plastic: Japan’s Strangest and Smartest Inventions

When you hear the word Japan, what comes to mind? Sushi? Cherry blossoms? Bullet trains?

All true—but Japan is also a global leader in science, technology, and innovation. It's the country behind some of the most groundbreaking inventions we use every day. Think of karaoke, 3D printing, or even emojis—they all originated in Japan!

But Japan isn’t only known for serious tech. It’s also famous for quirky, creative ideas that surprise the world—sometimes making us laugh, and other times making us think.

In this reading lesson, you’ll explore some of the strangest and smartest Japanese inventions. You’ll also build your English vocabulary, test your understanding, and discuss how innovation can shape the future.

🧠 Reading: Japan’s Weird and Wonderful Innovations

Japan has contributed many practical inventions to the modern world—electric cookers, blue LED lights, karaoke, and more. These tools are now part of daily life for millions of people.

But beyond these everyday creations, Japan is also known for its unusual and emotionally intelligent designs—inventions that help with loneliness, protect animals, or even improve how we eat.

Let’s take a look at a few of these.

🖐️ The Robot Hand That Squeezes Back

Imagine walking through the city and holding hands—not with a person, but with a robot hand.

It sounds strange, but in Japan, this is a real invention. Scientists created it for people who feel lonely and want comfort. The hand is made with a gel-like texture that feels like human skin. It even warms up, sweats, and can sense when you squeeze it—then it squeezes back.

For some, it may seem odd. But for others, it's a reminder that technology can also be about emotional connection.

🛍️ Plastic You Can Eat? Yes—If You're a Deer

In a popular park in Japan, several deer were found dead after accidentally eating plastic bags left by tourists. To solve this problem, one scientist invented edible plastic bags—but don’t worry, they’re not for people!

These bags, called “deer paper,” are made from milk cartons and bran. They look like normal plastic but are safe for animals to eat if dropped by mistake. It's a creative and environmentally friendly solution to a growing problem.

Imagine if this invention were used in parks around the world—how many animals could be saved?

😬 How Fast Do You Chew?

Japan has even invented a device to help you chew better.

It’s called a bitescan, and it looks like a small headset. It measures how fast and how often you chew. Why? Chewing slowly and properly helps digest food better and can reduce health problems like choking or stomach pain.

And just for fun, you can even compare your chewing speed with animals! 🐢🐇

This shows that even the smallest habits can be improved with technology.
