About :
The Tokaido Expressway spans Aichi, Mie, and Gifu. The camera went to the construction site of the Yoro Tunnel (tentative name), which is in the final construction section! As the dynamite is blown up, extremely rare machines appear one after another underground! ■Contents▼A tunnel that runs through the Yoro Mountains... Shocking scenes seen at the secret construction site Materials and people are transported by trolleys!? The "wheel drill jumbo," which is indispensable for tunnel construction, drills holes one after another in the hard rock! The secret construction site underground was a treasure trove of extremely rare footage that had never been seen before! ▼Blowing up the dynamite! We set up a camera at a very close distance and took a close-up shot of the moment! Dozens of sticks of dynamite are placed in holes in the rock! "1 minute before blasting," "10 seconds before blasting," "5, 4, 3, 2, 1, ignite!" The next moment, a tremendous blast blew through the tunnel! The reporting team filmed the moment of the explosion from close range! Flying debris hit the camera directly... is it okay!? ▼What!? A new huge tunnel was discovered next to the tunnel! Tunnels over 3,000 meters long are required to build a separate emergency tunnel called an "evacuation tunnel." The reporting team who was filming the "evacuation tunnel" also infiltrated the "main tunnel" where cars run! Since it is more than four times larger in scale, everything was dynamic, from the equipment used to the amount of dynamite! ■Cast: Hiraizumi Sei, Jogasaki Yuko◆"Nikkei Premium Let's Go to the Factory III" Program Summary The "factories" of the Tokai region are full of surprises! The Tokai region is a major base that supports Japanese manufacturing, but surprisingly little is known about what, where, and how it is made. So the camera infiltrates the "factory," the heart of manufacturing! Why did they take on the challenge of developing that product? Why did they become the world's No. 1 top share? What kind of wisdom and ingenuity is hidden in their proud factories? From super slow motion to the impressive footage using special cameras, to the divine skills of super craftsmen, to the unknown secrets of product development. The wonderful "world of manufacturing" that can only be seen here is here! ◆Program homepage https://tv-aichi.co.jp/koujou3/ ◆Factory fan site https://tv-aichi.co.jp/koujou_fan/ ◆Official Twitter / koujouheikou
