Driven by strong domestic stock performance and a weaker yen, publicly offered open-ended equity investment trusts experienced monthly net inflows exceeding 1 trillion yen for 10 consecutive months leading up to June 2026\. Total assets under management (AUM) officially broke through the 200 trillion yen threshold in May 2026. The defining structural transformation of the past decade remains the rapid adoption of index funds. The asset share of open-ended equity index funds (excluding ETFs) surged from approximately 12% in June 2016 to 41% in June 2026\. Within equity-only funds, the passive share now approaches 50%. Flagship low-cost funds—such as Mitsubishi UFJ Asset Management’s "eMAXIS Slim Worldwide Equity (All Country)" and "eMAXIS Slim US Equity (S&P 500)"—each crossed the 10 trillion yen AUM mark, sustained by inflows via the expanded NISA tax-exempt savings framework. ## Sign up for Japan FinTech Observer Cutting through the noise of Japanese Finance & FinTech Subscribe Email sent!

Nomura Asset Management held its rank as Japan's largest manager with 80.52 trillion yen in AUM as of June 30, 2026\. The top three firms—Nomura Asset Management, Mitsubishi UFJ Asset Management (57.49 trillion yen), and Daiwa Asset Management (42.50 trillion yen)—collectively account for over half of the market's total AUM across the top 60 firms. This concentration level closely mirrors the United States market, where Vanguard, BlackRock, and Fidelity control roughly half of total mutual fund assets. Concentration is notably more pronounced in passive strategies, where the top four asset managers control roughly 80% of passive AUM. This heavy centralization reflects both historic ETF purchasing programs by the Bank of Japan (BOJ) and retail flows into low-cost index products. Conversely, active management exhibits higher dispersion: the top five active managers account for only about 40% of total active AUM, creating a competitive landscape for alpha-driven managers. ![](https://storage.ghost.io/c/46/cb/46cbd57f-e0e8-41a4-a1e2-710103a4267b/content/images/2026/09/Screenshot-2026-09-14-at-18.45.13.png) ### Distribution Obstacles Restrain New Entrants and ETFs Despite regulatory initiatives by the Japanese government to ease entry barriers under its asset management nation policy, newcomer firms have struggled to gain substantial market share. Bank and broker distribution channels retain strong control over distribution, leaving independent and foreign firms with limited access to domestic retail networks. Consequently, top-tier domestic firms affiliated with major banking and brokerage groups dominate total asset volume. Foreign firms often establish market presence through sub-advisory agreements with Japanese managers, meaning actual market exposure for foreign managers is likely higher than direct direct-AUM metrics indicate. The retail ETF market in Japan remains small and overwhelmingly passive. ETF growth is constrained by legal and structural factors—specifically, the prohibition of ETF sales through traditional banking channels and less aggressive marketing by brokerage houses compared to mutual funds. Active ETFs were approved in 2023, but their overall market footprint remains limited. Nomura leads ETF assets with 59.34 trillion yen, followed by Amova Asset Management (26.78 trillion yen) and Daiwa Asset Management (25.70 trillion yen). ![](https://storage.ghost.io/c/46/cb/46cbd57f-e0e8-41a4-a1e2-710103a4267b/content/images/2026/09/Screenshot-2026-09-14-at-18.47.33.png) ### Lineup Concentration and Stewardship Evaluations Product concentration within individual fund houses is pronounced. Among the top 10 asset managers, seven have more than 50% of their total AUM concentrated in just their top five funds. For instance, despite managing over 670 individual funds, Nomura sees 72% of its total assets concentrated in its top five offerings—three of which are BOJ-backed ETFs. Conversely, firms such as Sumitomo Mitsui DS (22%), Sumitomo Mitsui Trust (27%), and Asset Management One (29%) exhibit broader product diversification. Morningstar evaluated 31 of the top 60 firms on qualitative Parent ratings, focusing on investment culture, talent retention, governance, fee philosophy, and stewardship rather than sheer asset size. - **High Rating:** Only three asset management firms achieved the top "High" Parent rating: Capital Group, J.P. Morgan Asset Management, and Sparx Asset Management. (Note: Tokai Tokyo Asset Management/Yucho-related entities and Hitachi Investment Management also reflect high stewardship marks in analyst disclosures). Smaller firms like Sparx (607 billion yen AUM) and Commons Asset Management ("Above Average", 117 billion yen AUM) demonstrate that operational scale does not correlate directly with high fiduciary marks. - **Above Average Rating:** Ten asset managers earned an "Above Average" rating, including Nomura Asset Management, Sumitomo Mitsui DS Asset Management, Fidelity International, BlackRock, Pictet, T. Rowe Price, State Street Investment Management, Schroders, Manulife, and Commons Asset Management. - **Rating Revisions:** J.P. Morgan Asset Management was upgraded from "Above Average" to "High" due to strong stewardship and long-term risk-adjusted track records. Conversely, T. Rowe Price was downgraded from "High" to "Above Average" following portfolio manager turnover and performance pressures in key equity strategies. Mirae Asset (Global X) saw its Parent rating downgraded from "Average" to "Below Average" due to governance and stewardship concerns surrounding short-term theme-based product launches. ![](https://storage.ghost.io/c/46/cb/46cbd57f-e0e8-41a4-a1e2-710103a4267b/content/images/2026/09/Screenshot-2026-09-14-at-18.49.33.png) ### Key Organizational Changes and Corporate Actions The report highlights major corporate restructurings and leadership transitions taking shape across the market in 2025 and 2026: - **Nomura Asset Management:** Effective April 1, 2026, former CEO Hiroyuki Koike transitioned to Chairman of NAM and Head of Investment Management at Nomura Holdings. Shoichi Okoshi, who previously served as Japan CEO for J.P. Morgan Asset Management for roughly a decade, was appointed as the new CEO—a notable shift from Nomura's traditional internal promotion path. Additionally, Nomura Holdings completed its acquisition of Macquarie Group's public asset management business in the U.S. and Europe in December 2025. - **Amova Asset Management (formerly Nikko Asset Management):** The firm rebranded to Amova Asset Management. Under CEO Stephanie Drews, Amova expanded its Asian platform by increasing its stake in Malaysia's AHAM Asset Management from 20.0% to 97.7% in June 2026\. In April 2026, it formed a joint venture in Singapore with Tikehau Capital to develop private asset strategies. - **SBI Global Asset Management:** In late 2025, SBIGAM adopted a multi-affiliate model. It integrated SBI Okasan Asset Management and Rheos Capital Works under its umbrella alongside SBI Asset Management, pooling active, passive, online, and traditional distribution models. - **Schroders & Nuveen Deal:** In February 2026, Nuveen announced an all-cash offer of approximately 9.9 billion GBP to acquire Schroders. The deal will privatize Schroders and delist it from the London Stock Exchange, creating a combined firm managing approximately $2.5 trillion in assets upon expected closing in Q4 2026. - **MetLife & PineBridge Integration:** MetLife Investment Management (MIM) completed its acquisition of PineBridge Investments in late 2025, adding approximately $100 billion in AUM to reach total assets exceeding $700 billion. - **Amundi & Victory Capital:** Amundi completed its deal with Victory Capital in April 2025, transferring its U.S. business (Pioneer) to Victory Capital in exchange for a 26% equity stake (4.9% voting rights) and a 15-year reciprocal distribution agreement. ### Star Ratings and Low-Cost Passive Performance Advantage Firms providing low-cost index products consistently secured higher average Morningstar Risk-Adjusted Ratings. State Street Investment Management scored an average Morningstar Rating of 3.79 stars, driven by its low-cost index lineup. Among major active asset managers, Fidelity International achieved the highest rating among top-10 providers with an average star rating of 3.54. The overall highest average Morningstar Rating across all evaluated 60 firms was achieved by Aozora Asset Management (4.18 stars), followed by Hitachi Investment Advisory (4.14 stars). Aozora’s outperformance stems largely from its strategic partnership with Dimensional Fund Advisors, whose systematic, rule-based active strategies delivered strong risk-adjusted returns at competitive fee levels. As fee competition accelerates across passive products, active managers are diversifying into private markets, unlisted equities, and sub-advisory structures to capture alpha, while voluntary disclosures of portfolio manager names are slowly expanding transparency across the domestic fund landscape. --- [Morningstar’s Analysis of the NISA MarketThe year 2025, the second following Japan’s landmark NISA reforms, saw a massive and steady flow of capital into the market, with total net inflows reaching approximately ¥14.2 trillion. However, this headline figure masks the year’s defining characteristic: a profound qualitative shift in how that capital is![](https://storage.ghost.io/c/46/cb/46cbd57f-e0e8-41a4-a1e2-710103a4267b/content/images/icon/Newsletter-Small-b47eae2b-e62a-4720-9018-c1b70b869da5.png)Japan FinTech ObserverNorbert Gehrke![](https://storage.ghost.io/c/46/cb/46cbd57f-e0e8-41a4-a1e2-710103a4267b/content/images/thumbnail/Morningstar-cfb250e5-ed44-4bf7-9d30-e56c5228cdcc.png)](https://www.fintechobserver.com/morningstars-analysis-of-the-nisa-market/)
