Japan Multifamily portfolio (JMF)

Urban migration, particularly to Japan’s ‘big four’ cities of Tokyo, Osaka, Nagoya and Fukuoka, and reduced household size are the secular trends that have driven the structural growth of the Japan multifamily sector. Between 2000-2020, for example, the average household size decreased by 16% while the total number of households jumped by 17% to 55.75 million.¹

Over the same period, the emergence of residential J-REITs around 2006 began the institutionalization of the sector. A surge in international interest from 2014 led to transaction volumes between 2015 and 2024 positioning Japan’s institutional-grade residential market as the largest and most established in Asia, and fourth largest in the world.² Japan multifamily today is considered a mature sector due to its stability, high occupancy rates and high renter population in major cities.

Against this backdrop, in 2019 PIMCO Prime Real Estate began assembling what would become a multi-billion-euro exposure to the sector with a €1.1 billion acquisition of an 82-asset portfolio. A second transaction for 11 newly built assets would follow six months later. Further transactions followed in early 2021 to create one of Japan’s  largest institutionally-owned residential portfolios.

Our investments target high-quality, centrally located assets – over 90% of the portfolio is within a 10-minute walk to the nearest train station – geared towards young professionals and recent graduates. Following every acquisition, we oversee a program of continuous improvement of the residential units to attract tenants, enhance asset performance, and meet investor expectations. For example, energy contracts are transitioned to renewable sources within three months of acquisition and tenants are actively incentivized to make sustainable choices. We have also steered our local property management partners to introduce an AI-powered metering solution in the assets to optimize energy use and reduce costs.

Today, the platform continues to perform well with occupancy consistently above 95% across the portfolio. The sector remains a high-conviction investment theme with demand underpinned by continued urbanization and a growing middle class, particularly in the ‘Big 4’ cities.³
