This program is brought to you by the Ogawa Seiki, a company that is familiar with the world's OS engines. In 1911, the first small engine was released in Japan and was exported to the United States. In 1913, the engine was developed. In the next generation, they have been looking at the small engines for more than 40 years. They just walk on this road. The OS engine, which always leads the world of small engines. Music The music involves running on a impact road. So today we will be talking about the Chikaraishi. I am Kanki Kenichi, a professor of physical education at Kobe University. Nice to meet you. What is the Chikaraishi? Chikaraishi is a kind of stone that was used by the young people in the Edo period. Is it found anywhere? It is found in most of Japan, but it is found in the temples of shrines. There are many photos of it. This one? There are many forms of it, such as the Great Earth and Chikaraishi. The most common is the egg-shaped one. The people of the nearby village compared it to the Chikaraishi. Did they play with it? Yes, I think there are many stories about the Chikaraishi. I think the most common is that they played with it. I think the Chikaraishi was not a stone at first. I think the Chikaraishi was based on the weight of rice. Is it all over Japan? Yes, it is all over Tokyo and Kyushu. It is not much in the north, but there is a wonderful stone called Shochikubai in the temple of Zoraifu. What is the closest to Kobe? There are two shrines in Nagata and two shrines in Kobe. Kobe was very far away from Kobe. Yes, Kobe was very far away from Kobe. And the In the past, people would ask for more pay because they were strong. In the past, people would ask for more pay. Yes, pay. That's the standard when you hire people. This is a port called Kasaoka. There are 15 or 16 power stones. The weight of the stones changes. I showed them with my strength. I thought it was good for me. I wanted to hire someone who was strong. That's a lot of work. It's like a test. As you do it, you get better at it. I have a band. It's like baseball. I have a band in Osaka. I got it from Kishi-kyoju of Shosan University. Koubei Shosen University. Kishi-kyoju has been doing this research. It's like a sumo wrestler's band. It's like a sumo wrestler's band. It's like a sumo wrestler's band. What year was it? It was three years ago. It's a very famous place. There are many photos. This is called Sanomia Unosuke. Sanomia is a name of Koubei? No. This is a person from Saitama Prefecture. There is a place called Sanomia. It's a name that can be seen all over the country. Sanomia Unosuke. There is a stone with the name of Sanomia Unosuke in the middle of the city. Was there a person with that name? No. This person was a professional. He was in the industry. He was the founder of the industry at that time. He was the founder of the industry at that time. It's hard to see because there are so many strong people. That's right. This is probably the most common thing in Edo. There are many ways to hold it. It's called Kyoku Mochi. You put your feet on the stone. You put a high-level stone on it and stand up to hold the stone. It's hard for an amateur to do. It's called Kyoku Mochi. It's quite difficult. But now it's called weightlifting. I don't think it's that original. It's hard to hold. Weightlifting is like a stick. It's easier to hold. It depends on how you hold it. Even if you have a lot of strength, if you don't have a good bone structure, you can't lift it. That's right. When you put a power stone on it, it's hard to hold. It's artificially shaped. There are many people who don't have a hand. It's said that if a person with a power of 70% has a stone, it can be used to hold the stone. Therefore, it is used to hold the stone. If you don't have the power of 70% to hold the stone, you can't lift it. I think it's a wisdom of life. There are many people who do this at shrines. It's not a star. Ordinary people do it, too. It's hard to hold. There are many people who get hurt. There are no records of such a thing. It's not out there. I think so. For example, I showed you the work of the power stone. This stone weighs about 280 kg. About 75 cans. Was this a big stone at that time? Yes, it was. It's the biggest stone I've ever looked into. This is it. When you step on a stone, it's a big stone. But the stone weighs 280 kg. 75 cans is 280 kg. What does 280 kg mean? Olympic athletes... The total weight of the athletes who won the Tokyo Olympics was 400 kg. 400 kg in total. They lifted the stone with the hard-to-holding power stone. They lifted it with their shoulders. There are many ways. There are many ways. There are records of that. This is the old stone? Yes, it was made in 1927. May 16. This is the stone of Murazumo in the area of Hirano River. This person lifted it and kept it in the records. He was 27 years old. It's a number. He was a little younger. There are many names. This is a small village. This is a village in the north of Hirano. This is a small village. This is a small village. This is a small village. This is a small village. When this started, all the villagers came. When this started, all the villagers came. This stone is carved with a lot of power. Is this all carved? Yes. It's a new era that the stone is carved and kept in records. I think that the stone was used to compete with the stones that were lying around. Why is this studied? I'm always asked this question. The power of moving the body is one of the areas of physical education. I'm very interested in human power. I'm interested in how much power the people of the past actually had. It's a record. I can now record the things that I used to play with. If I don't do that, I'll be an unknown existence. I want to write it down as far as I can understand it. That's the motivation for my research. I see. In the past, this very important stone was a business stone. Thank you for your interesting story today. Thank you. People have been dealing with various machines since ancient times. Eventually, the steam locomotive was born and traveled the world. 50 years of loving the steam locomotive, OS has continued its research. The evolution of the small engine, the Onawa century, and the new steam locomotive. This program was brought to you by Live Steam OS, a provider of the Onawa century.
