To achieve this objective, the Copyright Act does not regard the copyright holders\u2019 rights as absolute and provides specific limitations on rights that allow certain uses of copyrighted works without the copyright holder\u2019s consent as an exception to the general rule.&nbsp;<\/p>\n\n\n\n<p>These limitations are narrowly and strictly defined to avoid unjustifiably harming the copyright holder\u2019s interests and to prevent interference with the normal exploitation of works. They are a deliberate part of the statutory design\u2014not a loophole.<\/p>\n\n\n\n<p>This article explains two limitations that are frequently misunderstood in practice:&nbsp;<\/p>\n\n\n\n<p>(1) reproduction for private use in the context of corporate activity, and&nbsp;<\/p>\n\n\n\n<p>(2) reproduction in libraries, which can play an important role in research.<\/p>\n\n\n\n<p>In particular, what many people casually think of as \u201cprivate use\u201d often does not qualify as \u201cprivate use\u201d under the law, especially in corporate settings\u2014making this a key compliance

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Unlike the United States\u2019 broad, flexible fair use doctrine, Japan\u2019s limitations on rights are structured as a set of specific, enumerated exceptions. Each exception is defined by statute for particular purposes and methods of use. As a result, the default rule in Japan is that using a copyrighted work requires the copyright holder\u2019s permission, and permission is unnecessary only when the user\u2019s conduct fully satisfies the requirements of a statutory limitation.<\/p>\n\n\n\n<p>A core interpretive principle is that these provisions should not be applied in a way that unjustifiably harms the copyright holder\u2019s interests. In practice, even if a use appears to fit the literal wording of an exception, a court may still reject the exception if the use materially undermines the work\u2019s market value and substantially harms the copyright holder\u2019s economic interests.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reproduction_for_Private_Use_Under_Japanese_Copyright_Law_Article_30\"><\/span>Reproduction for Private Use Under Japanese Copyright Law (Article 30)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Article 30, paragraph 1 of the Japanese Copyright Act permits reproduction of copyrighted works for \u201cpersonal or family use or for any other use of a similarly limited scope.\u201d This is commonly referred to as <em>Reproduction for Private Use<\/em> and is one of the most fundamental limitations on rights. In general, three key requirements must be met:<\/p>\n\n\n\n<ul>\n<li><strong>The scope of use must be personal or similarly limited<\/strong>, such as within a household. This contemplates a very small, closed group\u2014typically family members or close friends\u2014and ordinarily does not include colleagues within a company.<br><\/li>\n\n\n\n<li><strong>The reproduction must be made by the user.<\/strong> In other words, the person who will use the work should make the copy themselves; outsourcing reproduction to an external service provider will generally not satisfy this requirement.<br><\/li>\n\n\n\n<li><strong>The purpose must be private use.<\/strong><\/li>\n<\/ul>\n\n\n\n<p>For corporate compliance purposes, the most important point is that reproduction for business purposes within a company does <strong>not<\/strong> fall within the scope of \u201cPrivate Use\u201d under Article 30. In the landmark copyright case: Tokyo District Court\u2019s decision of July 22, 1977, the court held that reproducing copyrighted works within a corporation or other organization for internal business use cannot be treated as personal use, nor as use within a similarly limited scope as within a household<\/p>\n\n\n\n<p>Source: <a href=\"https:\/\/www.courts.go.jp\/ip\/eng\/assets\/ip\/eng\/chizai_en\/chizai_en-pdf-2026.pdf\">&nbsp;Tokyo District Court &#8211; July 22, 1977 (Case number 1973 (Wa) 2198) Summary of Judgement<\/a>&nbsp;<\/p>\n\n\n\n<p>A corporation is a legal person, and its activities are not \u201cpersonal\u201d by nature. Moreover, because corporations exist for economic purposes and their members (employees) can be numerous and change over time, corporate use generally does not satisfy the \u201csimilarly limited scope\u201d requirement.<\/p>\n\n\n\n<p>Accordingly, even copies made solely for internal purposes\u2014such as duplicating newspaper articles for meeting materials or reproducing technical literature for research and development\u2014may require the copyright holder\u2019s permission. Proceeding without permission can create copyright infringement risk, and this is a compliance issue that is sometimes overlooked in cross-border business operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Exceptions_to_Private_Use_When_Reproduction_Is_Not_Permitted_Article_301i%E2%80%93iii\"><\/span>Exceptions to Private Use: When Reproduction Is Not Permitted (Article 30(1)(i)\u2013(iii))<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Article 30(1) permits reproduction for \u201cprivate use\u201d (personal, family, or similarly limited scope). However, that permission does not apply in the following cases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"i_Reproduction_Using_a_Public_Automated_Duplicator_Article_301i\"><\/span>(i) Reproduction Using a Public Automated Duplicator (Article 30(1)(i))<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The private-use exception does not apply when a user reproduces a work by means of an \u201cautomated duplicator\u201d that has been set up for use by the public. In other words, even if the user\u2019s purpose is private use, reproduction falls outside Article 30(1) when it is made using a publicly available automated copying device as described in the statute.<\/p>\n\n\n\n<p>However, there is an important carve-out. Supplementary provision Article 5-2 provides that, \u201cuntil otherwise provided for by law\u201d, automatic copying machines used exclusively for reproducing documents or drawings\u2014such as the copiers commonly found in convenience stores\u2014are excluded from this restriction. As a result, under current Japanese law, individuals may reproduce parts of books for private use using convenience store copiers.<\/p>\n\n\n\n<p>This reflects a policy judgment that distinguishes, for example, between the market impact of complete digital copies of music or video and the social convenience of everyday document copying. That said, the phrase <em>\u201cuntil otherwise provided for by law\u201d<\/em> signals that this approach could change through future legislative amendments.<br>Reference: <a href=\"https:\/\/www.cric.or.jp\/english\/clj\/clsp.html\" data-type=\"link\" data-id=\"https:\/\/www.cric.or.jp\/english\/clj\/clsp.html\">Copyright Law of Japan Supplementary Provisions<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"ii_Reproduction_Made_Possible_by_Bypassing_Technological_Protection_Measures_Article_301ii\"><\/span>(ii) Reproduction Made Possible by Bypassing Technological Protection Measures (Article 30(1)(ii))<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The private-use exception also does not apply where the reproduction has become possible due to the user bypassing \u201ctechnological protection measures\u201d, or where a barrier placed to prevent such reproduction no longer exists as a result of that bypass, and the user knowingly reproduces the work despite this.<\/p>\n\n\n\n<p>A key element in this article is the extent of the user\u2019s awareness: the exemption of private use does not apply when the user unlawfully reproduces the work while aware that technological protection measures were bypassed.<\/p>\n\n\n\n<p>Article 2, paragraph 1, item 20 defines \u201ctechnical protection measures\u201d as electric or magnetic measures, that are imperceptible to humans that placed in order <em>\u201cto prevent or deter a person from engaging in an action that constitutes infringement of an author&#8217;s moral rights or copyright\u201d<\/em><\/p>\n\n\n\n<p>For example, decrypting copy protection on DVDs or Blu-ray discs, or disabling encryption using specialized devices, is outside the private use exception even if the intent is personal viewing. Under this framework, legality is defined upon the <em>method<\/em> of reproduction, not merely the purpose or downstream use.<\/p>\n\n\n\n<p>Furthermore, Article 120-2 imposes criminal penalties for acts such as making available to the public devices or programs that enable bypassing, reflecting the statute\u2019s strict approach not only toward end users but also toward those who facilitate bypasses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"iii_Digital_Recording_from_an_Infringing_Automatic_Public_Transmission_Article_301iii\"><\/span>(iii) Digital Recording from an Infringing Automatic Public Transmission (Article 30(1)(iii))<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Finally, the private-use exception does not apply when a work is received via an automatic public transmission that infringes copyright (including an automatic public transmission made abroad that would infringe if transmitted in Japan), and the user records the sounds or visuals of the work in digital format, knowing that the transmission is infringing.<\/p>\n\n\n\n<p>Here too, the statutory trigger is not only the fact of infringement in the source transmission, but that the user records the work in the knowledge of that fact.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reproduction_in_Libraries_and_Similar_Facilities_Under_Japanese_Copyright_Law_Article_31\"><\/span>Reproduction in Libraries and Similar Facilities Under Japanese Copyright Law (Article 31)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Separate from private use, Article 31 provides a limitation on reproduction rights for certain public facilities. The provision reflects libraries\u2019 role as social information infrastructure and is intended to support public research activity.<\/p>\n\n\n\n<p>Covered institutions include the National Diet Library, public libraries, and university libraries, as defined by the Copyright Act Enforcement Ordinance. Corporate resource rooms and school libraries are generally not included within a &#8220;library or similar facility&#8221; for purposes of this provision. Another critical point is that the subject of the reproduction right under Article 31 is the \u201clibrary or similar facility\u201d, not the individual user themselves.<\/p>\n\n\n\n<p>The Tokyo High Court\u2019s decision of November 8, 1995 indicated that users cannot compel a library to reproduce materials based on Article 31. The decision whether to reproduce, and the responsibility for compliance, rests with the library. In this sense, libraries are not merely providers of copiers; they function as gatekeepers responsible for ensuring that reproduction is made only when the legal requirements are met.<\/p>\n\n\n\n<p>Source: <a href=\"https:\/\/www.courts.go.jp\/assets\/hanrei\/hanrei-pdf-13822.pdf\">The Tokyo High Court\u2019s &#8211; November 8, 1995 (Case Number Heisei 7 (Gy\u014dKo)&nbsp; 63) Summary of Judgement<\/a>&nbsp;<\/p>\n\n\n\n<p>Article 31, paragraph 1 limits reproduction without the author\u2019s permission primarily to the following three categories:<\/p>\n\n\n\n<ol>\n<li><strong>Reproduction for users\u2019 research (item 1).<\/strong> In general, only \u201ca single copy of a part of a work that has been made public\u201d may be reproduced, commonly understood as no more than half of the entire work.

They differ materially, however, in their legal basis, who may reproduce, the permissible purposes, and the allowable scope.<\/p>\n\n\n\n<p>Private use is designed for small-scale use within a closed personal sphere. Library reproduction is a tightly controlled service conducted by designated public institutions for broader societal purposes. In corporate settings, the private use exception generally does not apply, while library services may be used for research and study within the statutory limits and procedures.

The most important compliance takeaway\u2014supported by longstanding case law\u2014is that the private use exception does not apply to reproductions made for business purposes within a company. Misunderstanding this point can lead to inadvertent infringement risk.<\/p>\n\n\n\n<p>It is also important to recognize that copying by circumventing technological protection measures is unlawful regardless of the intended use, and that library reproduction is permitted only under strict, purpose-limited conditions administered by designated institutions. Because copyright law frequently evolves in response to technological and societal change, and because interpretation can be complex, companies often benefit from obtaining legal advice tailored to their specific use cases.<\/p>\n\n\n\n<p>Our firm advises domestic and international clients on Japanese copyright compliance, including issues that arise in cross-border business operations and digital-content use.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Japan\u2019s Copyright Act aims to protect the rights of creators while ensuring fair use for cultural works to encourage further evolution of culture.
