LOUBOUTIN LOSES RED SOLE LITIGATION IN JAPAN

Christian Louboutin has lost a major legal battle in Japan over his signature red sole trademark.

The Tokyo District Court ruled that the iconic red colour cannot be exclusively owned by the French luxury shoe designer, describing it instead as a “general design” commonly used in footwear across the industry. The lawsuit targeted Japanese shoemaker Eizo Collection, a company established in 1959, after Louboutin claimed that seven of its high-heeled shoes with red rubber soles infringed on his intellectual property rights under Japan’s Unfair Competition Prevention Law. He sought ¥42 million in damages, arguing that Eizo’s products could easily be mistaken for authentic Louboutins. Eizo responded that the red sole was neither original nor distinctive in Japan and had long been a design element in women’s footwear, pointing to both traditional lacquered clogs and modern high heels as examples.

Japan only began allowing registration of colour trademarks in 2015, following its entry into the Trans-Pacific Partnership, but so far, no single-colour marks have been approved—only multi-colour combinations. Louboutin previously applied to register his famous red sole in Japan, but his application was rejected and remains under appeal. In this case, the court issued a 39-page ruling in favour of Eizo, highlighting key differences between the two brands’ products. Louboutin’s shoes use glossy lacquered leather soles, while Eizo’s models rely on plain red rubber without any sheen. The judges concluded that these differences, combined with the widespread use of red in fashion, made it impossible to treat the colour as unique to Louboutin.

The court also considered factors such as pricing and consumer perception. Louboutin’s heels retail for at least ¥80,000 and are positioned firmly in the luxury market, whereas Eizo’s designs are much more affordable. According to the ruling, luxury shoe buyers are unlikely to confuse the two brands, since they typically rely on brand identifiers such as logos, labels, and store presentation. Furthermore, Louboutin’s commercial history in Japan spans only about two decades, which the court found insufficient to establish the red sole as a widely recognized brand symbol among Japanese consumers.

This outcome represents a significant setback for Christian Louboutin in Japan, where his efforts to protect his signature red sole have faced repeated challenges. While the designer has successfully registered his red sole trademark in more than 50 jurisdictions worldwide—including the United States, the European Union, the United Kingdom, India, and Australia—the Japanese ruling underscores how differently courts approach the distinctiveness of colour marks. For now, Japanese law does not recognise the red sole as uniquely Louboutin’s, and the fashion industry will be watching closely to see how his pending trademark appeal unfolds.
