Rikei

Well, "rikei" is a Japanese word that means "science" in English. And what is science? Science is like trying to solve puzzles about how things work in the world around us. Scientists use special tools and methods to figure out the answers to questions like "why does the sky look blue?" or "how do plants make their own food?". They do experiments and make observations to collect information, and then they use that information to come up with explanations and theories.

So "rikei" is kind of like a big group of people who are really interested in science and trying to learn more about the world. They might be scientists who work in labs or researchers who study things like the environment or the human body. But they could also be regular people who just really love learning about science and want to know more about how things work. And that's what "rikei" is all about - a love of science and a desire to learn more!
