The rise of e-commerce and small business entrepreneurship, which has increased the demand for storage spaces for business inventory, equipment, and documents, is driving the market.

Self storage is a service that provides individuals and businesses with storage space for their belongings, typically on a short-term basis, with facilities offering various-sized units that can be rented out to store items that may not fit in homes or offices. Known locally as "trunk room" rather than self storage, these facilities have expanded steadily across Kanto, Kansai/Kinki, Central/Chubu, Kyushu-Okinawa, Tohoku, Chugoku, Hokkaido, and Shikoku regions as Japan's compact urban living spaces drive sustained demand for additional storage solutions.

Japan Self Storage Market Trends and Drivers:

The self storage market in Japan has witnessed substantial growth owing to various factors, with increasing urbanization resulting in a surge in demand for storage facilities as people living in compact urban spaces seek additional space for their belongings. Rising disposable income among individuals has led to a greater inclination toward acquiring personal assets, thereby fostering the need for additional storage solutions and creating a positive impact on the market.

The growing e-commerce sector has significantly contributed to the expansion of the self storage market, as the flourishing online retail industry has created a notable increase in the requirement for warehousing and storage facilities to accommodate escalating inventory levels of businesses. Self storage facilities have become instrumental in providing cost-effective and convenient solutions for businesses to manage their inventory effectively, particularly as the market surpassed 14,860 storage locations nationwide in fiscal 2024, more than the number of family restaurants in the country.

Evolving demographic trends, such as the rising number of millennials and their transient lifestyles, are propelling demand for temporary storage spaces, while shrinking urban housing continues to be a core structural driver. According to industry surveys, Japan's self-storage market has expanded for 16 consecutive years since 2008, reaching approximately ¥85 billion in 2025 and projected to surpass ¥100 billion by 2027.
