Morihei is a knife and whetstone supplier based in Asakusabashi, Tokyo with over 100 years of history. At one point, more than 20 groups of blacksmiths and sharpeners worked under the name Morihei. Famously known for its extensive collection of whetstones and natural stones, the president Mr. Akimitsu Oguro is also an advisor for natural stone researchers from various universities and government groups. To this day, Morihei is one of the few remaining companies in Japan that has maintained the relationship between its blacksmiths and stonemakers for this long.
