Japanese investment into Cayman Islands fund structures continues to climb, with new figures highlighting growing demand for the jurisdiction’s unit trusts and other vehicles.
According to Cayman Finance, data from Japan’s Ministry of Finance shows Japanese portfolio assets in Cayman rose from 120.4 trillion Japanese yen at the end of 2023 to ¥128.4tn by the close of 2024.
Holdings in Cayman-domiciled investment funds have also increased steadily, reaching ¥101.1tn in 2024, up from ¥93.5tn a year earlier and ¥87.6tn in 2022.
Cayman remains one of the leading destinations for Japanese outward investment, accounting for 62.4% of Japan’s overseas investment fund holdings at the end of 2024.
Globally, the jurisdiction ranks second only to the United States for Japanese portfolio investment.
Local regulatory data further underscores the trend. Figures from the Cayman Islands Monetary Authority show there were 316 funds with Japanese investment managers in 2024, representing a combined US$103 billion in net assets.
In a press release on 6 May, Cayman Finance said the increase reflects broader shifts in Japan’s investment landscape.

After decades of low inflation and near-zero interest rates, rising prices have prompted investors to move away from cash holdings in search of higher returns, it explained.
This has driven greater interest in global and alternative assets such as private equity, private credit, hedge funds and infrastructure – many of which are accessed through Cayman-based fund structures.
Cayman Finance said the jurisdiction has also adapted its regulatory framework to accommodate this demand.
This includes the introduction of a dedicated registration pathway for unit trusts designed to align with Japanese regulatory, tax and reporting requirements while maintaining existing standards.
Samantha Widmer, director and head of funds and capital markets at Cayman Finance, said the figures point to sustained confidence among Japanese investors.
“Japan is one of the most important international markets for Cayman’s funds industry,” she said.
“The increasing use of Cayman demonstrates long-standing confidence in the jurisdiction’s legal framework, tax neutrality, regulatory credibility and the depth of its professional services ecosystem.”
She added that as Japanese investors continue to expand allocations to overseas and alternative strategies, Cayman is well positioned to support that growth, acting as a bridge between Japanese capital and international opportunities.
Further increases may be on the horizon, with the expansion of Japan’s Nippon Individual Savings Account programme expected to encourage households to shift savings into investments, alongside rising institutional allocations to private markets.
Widmer is due to visit Japan from 11 to 15 May as part of a Cayman delegation that includes Premier André Ebanks.
The group is expected to meet investment managers, institutional investors and advisers as part of efforts to strengthen ties with the Japanese market.
