日本の隠れた最強技術トップ20！！世界が手放せない企業ランキング

"Japanese technology is finished"—this is a must-see for anyone who thinks that. We'll show you all the Japanese companies the world can't live without, from 20th to 1st place. Almost 100 percent of the major computers sold worldwide today use a single Japanese company that makes a certain film inside. ▶ The "previous" video mentioned in this video—the top 20 defense companies (ranking by the Ministry of Defense's supply)—can be found in the "Related Videos" below. Being inconspicuous and lacking power are two completely different things. Today, we're not showing finished products, but the 20 components inside. Our measuring stick is simple: if that factory stopped tomorrow, what products would become unavailable and where in the world? 20th place is YKK in Kurobe, Toyama; 19th is Shimano in Sakai; 17th is Mabuchi Motor in Matsudo; and 16th is Olympus in Aizu (approximately 70% of the world market share for gastrointestinal endoscopes). Ranked 11th, Hamamatsu Photonics' photomultiplier tubes, which captured neutrinos at Kamiokande and led to the 2002 Nobel Prize in Physics, are now used in PET scans on the same principle. Ranked 10th, carbon fiber is produced by Toray, Teijin, and Mitsubishi Chemical, which together account for approximately 50-60% of the world's supply. Ranked 9th, Horiba, Ltd. in Kyoto, produces exhaust gas measuring devices used in all new cars worldwide, accounting for approximately 80% of the market. Ranked 6th, Japan Steel Works in Muroran, produces large forged steel products for nuclear reactor pressure vessels, accounting for approximately 80% of the market. And the top 5 are all semiconductor-related. ...Yet, the number one company is not a semiconductor company. ▼ What you'll learn from this video All of the companies ranked from 20th to 1st in the list of "What would stop being made and where in the world if that factory stopped tomorrow?" YKK, Shimano, Mabuchi Motor, Olympus – Global market share of things you already touch and use every day Heavy ion beam cancer treatment equipment, the seabed drilling ship "Chikyu," and Hamamatsu Photonics' "eye that counts light" that supported the Nobel Prize Carbon fiber, exhaust gas measuring equipment, nuclear reactor steel – Materials and equipment that, if stopped, would bring the entire industry to a halt Semiconductor materials and equipment that dominated the top 5 (high-purity hydrogen fluoride/mask blanks/silicon wafers/photoresists) And the number one company is not a semiconductor company – you'll probably doubt your ears when you hear the name Is a "95% global market share" really true? The story of honestly admitting that some things can't be said and dropping in the rankings. ▼ Table of Contents 0:00 Introduction - The misconception that "Japanese technology has declined" 1:59 Chapter 1: There is a measuring stick for this ranking 3:18 Chapter 2: From 20th to 16th place - We're already touching it today 7:25 Chapter 3: From 15th to 11th place - When the world demands precision 12:34 Chapter 4: From 10th to 6th place - If we stop, the industry stops 16:56 Chapter 5: From 5th to 1st place - The world's semiconductors pass through here 21:48 Final Chapter: Those who persevere are supporting the world ▼ Related Videos ・[2026 Edition] Top 20 Defense Companies!!
