Within 12 months, two international insurers have launched competing parametric earthquake products for corporate clients in Japan – a development that reflects both the scale of the country’s seismic exposure and a shift in the regulatory and market conditions that previously limited international parametric capacity in this segment. Munich Re Specialty announced July 28 the launch of a parametric earthquake insurance product for corporate clients, delivered through the Lloyd’s Japan platform and backed by Munich Re Capital Partners, the group’s alternative risk transfer unit. The announcement follows the receipt by HDI Global SE of authorisation from Japan’s Financial Services Agency (FSA) in July 2025 to offer a comparable product developed with Descartes Underwriting. For brokers and corporate risk managers, the two launches create a product selection decision in a segment where structured alternatives to conventional indemnity cover were, until recently, limited.
Japan records approximately 1,500 noticeable earthquakes annually, according to Munich Re Specialty. Despite that exposure, Japan Earthquake Reinsurance Co. (JER) data published in Toa Re’s Japan’s Insurance Market 2025 shows the household earthquake insurance penetration rate against total dwellings stood at 35.1% – fewer than four in 10 households covered. The corporate protection gap is different in character but equally significant: standard indemnity policies require demonstrated physical damage before a claim is paid, leaving operational disruption without physical loss – a routine seismic outcome for manufacturers, logistics operators, and service businesses – largely uninsured. Swiss Re Institute’s sigma 1/2025 report, published in April 2025, estimated that a repeat of the 1995 Kobe earthquake today could generate $200 billion in economic losses against $35 billion insured, while a repeat of the 2011 Great East Japan earthquake could produce $300 billion in economic losses against $80 billion insured. The gap between those figures is the commercial case for parametric structures.
Aon’s Alternative Risk Transfer practice noted in a May 2025 analysis that the market for natural catastrophe exposures is not just about price, but also about terms and conditions, and that parametric, for all intents and purposes, does not carry deductibles, exclusions, or sub-limits – characteristics that become particularly relevant when underwriters tighten their approach in catastrophe-prone markets. Peter Lacovara, managing director in Aon’s Alternative Risk Transfer and Innovation practice, North America, said: “The market for nat-cat exposures is not just about price, but terms and conditions, too. And parametric, for all intents and purposes, does not have terms and conditions, deductibles, exclusions, or sub-limits – and that’s where it shines.”
The Munich Re Specialty and HDI Global products use different data sources, a technical distinction with practical significance for buyers evaluating basis risk – the risk that a payout may not correlate precisely with losses at a specific location. Munich Re Specialty’s product draws on data from the Kik-net and K-NET networks. Both are operated by Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED). K-NET comprises 1,039 surface-mounted strong-motion observation stations distributed at approximately 20 km intervals across Japan, while Kik-net consists of 695 stations each equipped with paired surface and borehole seismographs, as of April 1, 2025. The borehole component of Kik-net records ground motion below the surface layer, reducing distortion from local soil amplification effects.
The HDI Global and Descartes product is triggered when an agreed threshold on the Japan Meteorological Agency’s (JMA) Shindo seismic intensity scale is reached, enabling predefined payouts without the need for traditional loss adjustment. The Shindo scale measures the intensity of ground shaking at a specific location, whereas Munich Re Specialty’s product relies on strong-motion observation data from the K-NET and KiK-net networks. For corporate buyers, the differing trigger methodologies may influence basis risk – the possibility that a parametric payout does not fully align with the operational impact experienced at a particular site, particularly where local geology or the location of monitoring stations affects recorded shaking.
Under Japan’s Insurance Business Act, foreign insurance companies may conduct insurance business in Japan only if they have opened a branch and obtained the applicable licence from the FSA. The Lloyd’s Japan platform satisfies that requirement for Munich Re Specialty, while HDI Global obtained direct FSA authorisation. The FSA’s strategic priorities for fiscal year 2025, published in August 2025, stated that the regulator would encourage companies to focus on risk management through the use of non-life insurance. Lloyd’s gross written premium reached £57.9 billion in full-year 2025, with total capital, reserves, and subordinated loan notes of £49.8 billion, according to the market’s annual results published in March 2026.
Stephanie Ogden (pictured), CEO at Munich Re Specialty – Global Markets, Syndicate, said: “This parametric structured product meets a real, historic, and daily challenge for businesses across Japan. Our role is to help businesses continue their routine operational practices in the face of the devastating impacts of natural catastrophes. Here, we enhance our purpose by enabling fast claims settlements and harnessing global collaboration, skillsets, and knowledge across Munich Re.”
Emma Loynes, CEO of Asia-Pacific, Middle East, and Africa and country manager of Singapore at Lloyd’s, said: “This is a strong example of Lloyd’s international platform enabling specialist underwriting expertise to reach clients in key markets. By combining global risk capital with local access through Lloyd’s Japan, we can help the market respond to client needs with solutions that are innovative, relevant, and resilient.”
In full-year 2025, Asia accounted for approximately 30% of global economic catastrophe losses while representing only around 5% of insured losses, according to Swiss Re sigma research published in March 2026. The Geneva Association’s February 2026 report on public-private insurance programmes noted that between 1980 and 2025, natural catastrophes caused an estimated $7.4 trillion in property losses globally, of which two-thirds were uninsured. Japan’s position as a market with relatively high non-life penetration by regional standards – yet persistent earthquake protection gaps at the corporate level – makes it a distinct target for the product category. The arrival of two competing parametric earthquake products in 12 months, using different technical approaches to trigger design, gives the corporate segment a structural comparison point that did not previously exist.
