Trunk Room Awareness at 98.1%, Usage at 22.8%: Urban Expansion and Future Growth Forecast [Storage Reality Survey 2026]

Due to shrinking homes and diversifying lifestyles, lack of home storage is a growing issue, making trunk rooms (self-storage) an attractive solution. A recent survey reveals that while 98.1% of people are aware of trunk rooms, only 22.8% have actually used them. Usage is particularly high in Tokyo at 48.6%. Users are mainly in their 30s and 40s. Urban residents primarily use them during moving, while regional users store hobby or seasonal items. With 71.3% expecting storage shortages to worsen, nationwide demand is projected to grow significantly.
