Message from Founder

Due to demographic changes, a transforming economy, and an evolving regulatory environment, we believe Japan-linked private markets offer unique opportunities for international asset managers and professional investors interested in establishing long-term relationships with market participants.

In 2023, the total deal value of fund-backed mergers and acquisitions of Japanese companies reached a historic high of JPY 5.3 trillion (approximately $123 billion), marking a significant 23% increase from the previous year, according to Bain & Co. From 2021 to 2023, private equity deals in Japan grew by 49%, the highest rate among all countries in the Asia region, according to Arc Group. This surge underscores the dynamic nature of Japan's private markets and the growing interest from institutional investors.

At J-Sils Partner, we navigate these exciting yet intricate market conditions to assist mandates that potentially generate superior risk-adjusted returns. These mandates emphasise ESG and sustainable solutions as we believe sustainability plays a pivotal role in enhancing long-term returns while providing risk management for all stakeholders.

We are delighted to hear from you about your projects for your long-term financial and business portfolios within Japan-linked private markets.
