As specified in Article 45(2) of Regulation (EU) 2016/679, the adoption of an adequacy decision has to be based on a comprehensive analysis of the third country's legal order, with respect to both the rules applicable to the data importers and the limitations and safeguards as regards access to personal data by public authorities. The assessment has to determine whether the third country in question guarantees a level of protection "essentially equivalent" to that ensured within the European Union (recital 104 of Regulation (EU) 2016/679). As clarified by the Court of Justice of the European Union, this does not require an identical level of protection (2). In particular, the means to which the third country in question has recourse may differ from the ones employed in the European Union, as long as they prove, in practice, effective for ensuring an adequate level of protection (3). The adequacy standard therefore does not require a point-to-point replication of Union rules. Rather, the test lies in whether, through the substance of privacy rights and their effective implementation, supervision and enforcement, the foreign system as a whole delivers the required level of protection (4).

The APPI has been reformed in recent years. The amended APPI was promulgated on 9 September 2015 and came into force on 30 May 2017. The amendment introduced a number of new safeguards, and also strengthened existing safeguards, thus bringing the Japanese data protection system closer to the European one. This includes, for instance, a set of enforceable individual rights or the establishment of an independent supervisory authority (PPC) entrusted with the oversight and enforcement of the APPI.

The APPI has been reformed in recent years. The amended APPI was promulgated on 9 September 2015 and came into force on 30 May 2017. The amendment introduced a number of new safeguards, and also strengthened existing safeguards, thus bringing the Japanese data protection system closer to the European one. This includes, for instance, a set of enforceable individual rights or the establishment of an independent supervisory authority (PPC) entrusted with the oversight and enforcement of the APPI.

Requirements applicable to anonymously processed personal information, as defined in Article 2(9) of the APPI, are stipulated in Section 2 of Chapter 4 of the Act ("Duties of an Anonymously Processed Information Handling Business Operator"). Conversely, such information is not governed by the provisions of Section 1 of Chapter IV of the APPI which includes the articles stipulating the data protection safeguards and rights applying to the processing of personal data under that Act. Consequently, while "anonymously processed personal information" is not subject to the "standard" data protection rules (those specified in Section 1 of Chapter IV and in Article 42 of the APPI), they do fall within the scope of application of the APPI, notably Articles 36 to 39.

In order to ensure an adequate level of protection of personal data transferred from the European Union to business operators in Japan, only processing of personal information falling within the scope of Chapter IV of the APPI – i.e. by a PIHBO to the extent the processing situation does not correspond to one of the sectoral exclusions – should be covered by this Decision. Its scope should therefore be aligned to that of the APPI. According to the information received from the PPC, where a PIHBO covered by this Decision subsequently modifies the utilisation purpose (to the extent this is permissible) and would then be covered by one of the sectoral exclusions in Article 76 of the APPI, this would be considered as an international transfer (given that, in such cases, the processing of the personal information would no longer be covered by Chapter IV of the APPI and thus fall outside its scope of application). The same would apply in case a PIHBO provides personal information to an entity covered by Article 76 of the APPI for use for one of the processing purposes indicated in that provision. As regards personal data transferred from the European Union, this would therefore constitute an onward transfer subject to the relevant safeguards (notably those specified in Article 24 of the APPI and Supplementary Rule (4)). Where the PIHBO relies on the data subject's consent (25), it would have to provide him/her with all the necessary information, including that the personal information would no longer be protected by the APPI.

Specific safeguards should exist where "special categories" of data are being processed.

While the concept of "sensitive" data is inherently a social construct in that it is grounded in cultural and legal traditions, moral considerations, policy choices etc. of a given society, given the importance of ensuring adequate safeguards to sensitive data when transferred to business operators in Japan the Commission has obtained that the special protections afforded to "special care-required personal information" under Japanese law are extended to all categories recognised as "sensitive data" in Regulation (EU) 2016/679. To this end, Supplementary Rule (1) provides that data transferred from the European Union concerning an individual's sex life, sexual orientation or trade-union membership shall be processed by PIHBOs "in the same manner as special care-required personal information within the meaning of Article 2, paragraph 3 of the [APPI]".

Concerning the additional substantive safeguards applying to special care-required personal information, according to Article 17(2) of the APPI, PIHBOs are not allowed to acquire such type of data without prior consent of the individual concerned, subject only to limited exceptions (38). Furthermore, this category of personal information is excluded from the possibility of third party disclosure based on the procedure provided for under Article 23(2) of the APPI (allowing transmission of data to third parties without the prior consent of the individual concerned).

Finally, the APPI creates a framework for the participation of sectoral industry organisations in ensuring a high level of compliance (see Chapter IV, Section 4). The role of such accredited personal information protection organisations (40) is to promote the protection of personal information by supporting businesses through their expertise, but also to contribute to the implementation of safeguards, notably by handling individual complaints and helping to solve related conflicts. To that end, they may request participating PIHBOs, if appropriate, to adopt necessary measures (41). Moreover, in case of data breaches or other security incidents PHIBOs shall in principle inform the PPC as well as the data subject (or the public) and take necessary action, including measures to minimise any damage and to prevent any recurrence of similar incidents (42). While those are voluntary schemes, on 10 August 2017 the PPC had listed 44 organisations, with the largest one, Japan Information Processing and Development Center (JIPDEC), alone counting 15 436 participating business operators (43). Accredited schemes include sector associations such as for instance the Japan Securities Dealers Association, the Japan Association of Car Driving Schools or the Association of Marriage Brokers (44).

To ensure continuity of protection in case of personal data transferred from the European Union to Japan under this Decision, Supplementary Rule (4) enhances the level of protection for onward transfers of such data by the PIHBO to a third country recipient. It does so by limiting and framing the bases for international transfers that can be used by the PIHBO as an alternative to consent. More specifically, and without prejudice to the derogations set forth in Article 23(1) of the APPI, personal data transferred under this Decision may be subject to (onward) transfers without consent only in two cases: (i) where the data is sent to a third country which has been recognised by the PPC under Article 24 of the APPI as providing an equivalent level of protection to the one guaranteed in Japan (47); or (ii) where the PIHBO and the third party recipient have together implemented measures providing a level of protection equivalent to the APPI, read together with the Supplementary Rules, by means of a contract, other forms of binding agreements or binding arrangements within a corporate group. The second category corresponds to the instruments used under Regulation (EU) 2016/679 to ensure appropriate safeguards (in particular, contractual clauses and binding corporate rules). In addition, as confirmed by the PPC, even in those cases, the transfer remains subject to the general rules applicable to any provision of personal data to a third party under the APPI (i.e. the requirement to obtain consent under Article 23(1) or, alternatively, the information requirement with a possibility to opt out under Article 23(2) of the APPI). In case the data subject cannot be reached with a request for consent or in order to provide the required advance information under Article 23(2) of the APPI, the transfer may not take place.

Finally, a further safeguard in case of (onward) transfers follows from Articles 20 and 22 of the APPI. According to these provisions, where a third country operator (data importer) acts on behalf of the PIHBO (data exporter), that is as a (sub-) processor, the latter has to ensure supervision over the former as regards security of data processing.

The Commission has also assessed the limitations and safeguards, including the oversight and individual redress mechanisms available in Japanese law as regards the collection and subsequent use of personal data transferred to business operators in Japan by public authorities for public interest, in particular criminal law enforcement and national security purposes ("government access"). In this respect, the Japanese government has provided the Commission with official representations, assurances and commitments signed at the highest ministerial and agency level that are contained in Annex II to this Decision.

Japanese law contains a number of limitations on the access and use of personal data for criminal law enforcement purposes as well as oversight and redress mechanisms that provide sufficient safeguards for that data to be effectively protected against unlawful interference and the risk of abuse.

Also, according to the information received only four government entities are empowered to collect electronic information held by Japanese business operators on national security grounds, namely: (i) the Cabinet Intelligence & Research Office (CIRO); (ii) the Ministry of Defence ("MOD"); (iii) the police (both National Police Agency (NPA) (125) and Prefectural Police); and (iv) the Public Security Intelligence Agency ("PSIA"). However, the CIRO never collects information directly from business operators, including by means of interception of communications. Where it receives information from other government authorities in order to provide analysis to the Cabinet, these other authorities in turn have to comply with the law, including the limitations and safeguards analysed in this Decision. Its activities are thus not relevant in a transfer context.

Therefore, the Commission should on an on-going basis monitor the situation as regards the legal framework and actual practice for the processing of personal data as assessed in this Decision, including compliance by the Japanese authorities with the representations, assurances and commitments contained in Annex II. To facilitate this process, the Japanese authorities are expected to inform the Commission of material developments relevant to this Decision, both as regards the processing of personal data by business operators and the limitations and safeguards applicable to access to personal data by public authorities. This should include any decisions adopted by the PPC under Article 24 of the APPI recognising a third country as providing an equivalent level of protection to the one guaranteed in Japan.

To this end, this Decision should be subject to a first review within two years after its entry into force. Following that first review, and depending on its outcome, the Commission will decide in close consultation with the Committee established under Article 93(1) of the GDPR whether the two-year-cycle should be maintained. In any case, the subsequent reviews should take place at least every four years (151). The review should cover all aspects of the functioning of this Decision, and in particular the application of the Supplementary Rules (with special attention paid to protections afforded in case of onward transfers), the application of the rules on consent, including in case of withdrawal, the effectiveness of the exercise of individual rights, as well as the limitations and safeguards with respect to government access, including the redress mechanism as set out in Annex II to this Decision. It should also cover the effectiveness of oversight and enforcement, as regards the rules applicable to both PIHBOs and in the area of criminal law enforcement and national security.

To perform the review, the Commission should meet with the PPC, accompanied, where appropriate, by other Japanese authorities responsible for government access, including relevant oversight bodies. The participation in this meeting should be open to representatives of the members of the European Data Protection Board (EDPB). In the framework of the Joint Review, the Commission should request the PPC to provide comprehensive information on all aspects relevant for the adequacy finding, including on the limitations and safeguards concerning government access (152). The Commission should also seek explanations on any information relevant for this Decision that it has received, including public reports by Japanese authorities or other stakeholders in Japan, the EDPB, individual DPAs, civil society groups, media reports, or any other available source of information.

Where, on the basis of the regular and ad hoc checks or any other information available, the Commission concludes that the level of protection afforded by the Japanese legal order can no longer be regarded as essentially equivalent to that in the European Union, it should inform the competent Japanese authorities thereof and request that appropriate measures be taken within a specified, reasonable timeframe. This includes the rules applicable to both business operators and Japanese public authorities responsible for criminal law enforcement or national security. For example, such a procedure would be triggered in cases where onward transfers, including on the basis of decisions adopted by the PPC under Article 24 of the APPI recognising a third country as providing an equivalent level of protection to the one guaranteed in Japan, will no longer be carried out under safeguards ensuring the continuity of protection within the meaning of Article 44 of the GDPR.

The European Parliament has adopted a resolution on a digital trade strategy that calls on the Commission to prioritise and speed up the adoption of adequacy decisions with important trading partners under the conditions laid down in Regulation (EU) 2016/679, as an important mechanism to safeguard the transfer of personal data from the European Union (155). The European Parliament has also adopted a resolution on the adequacy of the protection of personal data afforded by Japan (156).
