Teranishi Chemical Industry

Founded in 1916, Teranishi Chemical Industry is a pillar of Japanese heritage, recognized by its iconic “Guitar” trademark. The company secured its place in history in 1953 by pioneering “Magic Ink”, Japan’s first oil-based permanent marker, which revolutionized writing culture across the country. Originally masters of industrial ink and watercolors, Teranishi has successfully evolved into a boutique favorite for modern hobbyists. Their acclaimed “high colour” fountain pen inks and specialized markers are prized for their rich pigmentation and reliable performance. Today, Teranishi continues to blend its century-long chemical expertise with a refined, nostalgic aesthetic that appeals to the most discerning creative writers.
