TL;DR

1 社of the 2 社domestic credit rating agencies in the Japanese capital market (the other 1 社being R&I). Established 1985-04 , it positions itself as independent (it has no specific financial-group parent company). It provides ratings across the full range of sovereign / financial institution / corporate / securitized products / project finance / sustainability finance. It holds credit-rating-agency registration under the Financial Instruments and Exchange Act (registered with the FSA Commissioner) and is eligible as an ECAI (External Credit Assessment Institution) under both Japanese and Basel standards. Compared with the global 3 majors (S&P / Moody’s / Fitch), a tendency for its ratings on Japanese companies to be 1–2 notches more lenient has long been pointed out.

The domestic-vs-international rating-gap issue

• Empirical research confirms a tendency for JCR / R&I ratings on Japanese companies to be higher than S&P / Moody’s (typically 1–2 notches higher, with gaps of 4 notches or more reported in some cases) — Bank of Japan working paper “Credit Rating Gaps in Japan” (2007) and other peer-reviewed papers
• Background: a relative-assessment methodology that factors in Japanese companies’ main-bank system and group-rescue practices (empirical research explains this as a systematic difference in credit-risk assessment methodology rather than an “upward bias”)
• While international investors continue to criticize “Japanese ratings for optimistic bias,” there are also counterarguments that they reflect the realities of the domestic market
• Many Japanese companies obtain ratings from 2 社 and above (combining domestic and international is the standard practice)

Competitive characteristics

• Positions itself as independent (differentiated by the fact that it has no specific financial-group parent company, in contrast to R&I, which is seen as “Mizuho-affiliated”)
• Holds a relatively high issuer-rating share among mid-tier and small-to-medium-sized enterprises
• A front-runner in sustainability-assessment work (provides SPOs conforming to the GBP / SBP / SLBP principles)

4. Supervision / regulation

• Supervising authority: Financial Services Agency (FSA) (credit-rating-agency supervision)
• Governing law: Article 66 -27 and following of the Financial Instruments and Exchange Act
• Registration requirements: business-management framework, conflict-of-interest prevention, documentation of the rating process, complaint-handling framework, etc.
• ECAI accreditation: External Credit Assessment Institution accreditation based on Basel Committee on Banking Supervision standards (FSA public notice) → usable in banks’ risk-asset calculations
• International coordination: conformity with the IOSCO Code of Conduct for credit rating agencies
