On April 10, 2026, the day the new Hokuto no Ken anime adaptation launched on Prime Video, the Japanese brand Super Tool released two limited edition adjustable wrenches in the colors of Kenshiro and Raoh. A goodie as quirky as it is unprecedented, yet entirely official, announced directly on the website of Tetsuo Hara.
The Legend of the End-of-Century Tools
Here is the name given to this unexpected collaboration: “Seikimatsu Kougudensetsu”, literally “The Legend of the End-of-Century Tools”. Two extra-wide adjustable wrenches, produced by Super Tool, a Japanese professional tool manufacturer founded in Osaka in 1918, are behind this epic name.
The retail price of the Kenshiro (MWG38K) is 4,250 yen, tax excluded. The larger model, the Raoh (MWG50R), sells for 5,220 yen tax excluded. Both feature the colors and visual identity of their respective characters.
Real professional tools featuring Hokuto no Ken
This is not just a decorative gadget. Both models are based on a pro-type adjustable wrench (super-wide monkey wrench), compact and lightweight while offering an extra-wide opening. The strength is JIS Level H certified (the Japanese professional standard), making it a tool suitable for real job sites. The design combines the visual identity of the characters with the durability demanded by craftsmen, according to the manufacturer.
