In the context of trademark law, a "trademark" encompasses more than just text, figures, and symbols; it also includes three-dimensional shapes or combinations thereof (marks) used by businesses to distinguish their goods or services from those of competitors.

Japan’s Trademark Act provides broad protection for these visually recognizable elements. Marks that incorporate three-dimensional shapes into their composition are specifically referred to as "3D Trademarks" (Rittai Shohyo).

Iconic Examples and Their Impact

Famous examples of registered 3D trademarks in Japan include:

• Fujiya’s "Peko-chan" and "Poko-chan"
• KFC’s "Colonel Sanders"

These 3D figures serve as powerful "advertising towers" in front of retail stores. Simply seeing them allows consumers to immediately recognize that specific cakes or fried chicken are available at that location. In these instances, the 3D figure itself becomes the brand’s hallmark, fully functioning as a trademark.

Evolution of the System

Historically, the Japanese trademark system only recognized two-dimensional text and figures. However, following international trends in intellectual property protection, the law was amended in 1997 (Heisei 9) to establish the current 3D trademark system.

Thanks to this system, protection now extends beyond character dolls to include:

• Distinctive container shapes, such as the Coca-Cola bottle.
• Distinctive building exteriors and interiors, such as those seen with Komeda’s Coffee.

Challenges in Registration

Registering a 3D trademark involves practical complexities. During the examination process, applications are often rejected if the shape is deemed "commonplace" or "necessary to fulfill the product's function," as the law aims to prevent a single company from monopolizing functional designs.

However, if a mark—like Peko-chan—has been used for so long that society widely recognizes it as belonging to a specific store, the likelihood of it being granted strong legal rights increases significantly under Article 3, Paragraph 2 of the Trademark Act.

Why Register?

By registering a 3D trademark, a company can:

• Prevent confusion: Stop competitors from placing similar figures in front of stores to mislead consumers.
• Legal Guarantee: Formally secure the legal protection of the brand's unique identity and originality.
