Section 5. Trademark and Design Protection Systems

5.7 Protection of designs

5.7.1 Scope of protection

Under Japan's Design Law, protection is available for the form, pattern or color of an object or a combination of these, which appeals visually to the viewer's sense of aesthetics. Put simply, Japan's system protects the shape, form and external appearance of an object.

Furthermore, under the Law revised in FY2006, screen designs (for example, screen designs for recording schedule menu of DVD recorders, those for selecting contacts to make phone calls on mobile phones, and those for selecting prints of photo printers) are protected as the form of parts of goods, subject to certain requirements.

Also, from the recent viewpoint of emphasizing space design, the FY2019 revision of the Law protects the exterior and interior design of buildings. Along with the spread of new technologies such as IoT, the FY2019 revision also protects images not recorded or displayed on goods, such as images stored on clouds and provided over networks and images projected on roads.

  1. (1)


    1. a.

      Visual appeal to aesthetic sense

      Objects whose form cannot be recognized by the human eye, such as a single grain of powder, do not meet this criterion.

    2. b.

      Industrial usability

      The design must be able to be recreated using an industrial (mechanical or hand-based) process and must be able to be mass-produced.

  2. (2)

    Examination criteria

    1. a.


      No identical or similar design must have been in existence before the application was made; in other words, the design must be completely new.

    2. b.

      Ease of creation

      No design that is adjudged to be lacking creativity will be registered, regardless of whether or not it is new.

    3. c.


      Designs that are either identical or similar to other designs for which applications have been filed or which have been registered are not deemed to be newly-created designs, and will therefore not be registered (except for the application filed by the same person).

    4. d.


      From a standpoint of public interest, the following designs will not be registered.

      • Designs that may breach public order and morals.
      • Designs of goods, structures or images that may cause confusion with any item pertaining to the business of any other person.
      • Designs consisting of only the minimum form necessary to ensure the functions of the object, basic shape for particular building usage, or indispensable display for image applications.
    5. e.

      One design per application

      Discrete applications must be made for each design. In order to simplify application procedures, the FY2019 revision has abolished the "Classification of Articles" stipulated by the Ministry of Economy, Trade and Industry Decree, and allowed applications for design registrations for multiple designs in a single application form.

    6. f.


      If more than one application is filed for the registration of two identical or similar designs, the application filed first will be eligible for registration. If the same person files two identical or similar design applications within a certain period, one of which is deemed as the original design and the other is deemed as a related design, both designs will be eligible for registration under the related design system.

5.7.2 Term of protection

Protection of design rights begins once a design is registered, and the effective period for protection is 25 years from the filing date under the FY2019 revision. However, it is important to note that, contrary to trademarks, it is necessary to pay an annuity each year in order to maintain protection. Furthermore, while design rights generally lapse upon the passing of 25 years from the filing date of the application, if the form of the registered object becomes famous, it is possible to receive protection under the Unfair Competition Prevention Law even after design rights lapse.

5.7.3 A protection system unique to Japan

Japan's Design Law provides a system of protection that is very unique to this country. Below are some major examples of this.

  1. (1)

    Related design system

    Under Japan's Design Law, not only are designs originally registered in relation to a certain object protected, but similar designs related to that object and filed within 10 years from the filing date of the application are also protected. However, if you feel that official advance confirmation is required regarding the extent to which your design is similar to the one registered, you may register your design as a "similar design." Furthermore, as a result of the FY2019 revision of the Law, it has become possible to register designs similar only to related designs, which was not possible in the past.

  2. (2)

    Design of a set of objects

    Under the provisions of Japan's Design Law, design applications and registration usually follow a one-design-per-object principle, however there is an exception to that rule. This exception allows for discrete objects that common sense dictates are usually sold as a set---a knife, fork, and spoon, for example---to be registered as a single design of a set of objects. Intelligent use of this system has the advantage of helping keep costs to a minimum. As a result of the FY2019 revision, partial design registrations for packages have become possible that were not available previously.

  3. (3)

    Secret designs

    When a design is registered, it is generally published in the Design Gazette, however Japan offers a system that allows a registered design to be kept a secret for a certain period upon application. This is known as the "Secret Design" system. Because designs are influenced so strongly by fads and fashions, and because some products' periods of popularity tend to end sooner than others', this system aims to protect the rights of the design-owners for a certain period of time. It should be noted, however, that this system tends to limit litigators' options when suing for infringement of rights, and so the system is used infrequently at best.

  4. (4)

    Partial designs

    Because traditionally design rights have protected an entire object, protection could not be guaranteed against infringement by people who copied only parts of a design. However, under a revision to the law in 1998, the partial design system was introduced allowing registration of parts of shapes or forms with distinct characteristics. Thus, while it used to be that if somebody copied only part of a design they would escape prosecution as long as the overall design was not similar, the new system allows registration of partial designs, meaning that infringements can be prosecuted. Indeed, this is one of the most important aspects of Japan's Design Protection system.
