A survey conducted by our company revealed that approximately 80% of people nationwide have experienced trouble with home storage space. On the other hand, the trunk room usage experience rate is about 20%, indicating a situation where it is hard to say that trunk rooms are fully utilized by those who suffer from storage problems. However, more than half of the non-user demographic answered that they "would like to use one if the conditions are met," suggesting the breadth of a potential market.
In this report, we analyze the reality of storage issues and the potential of the trunk room market based on the questionnaire.
Survey highlights:
- Experienced trouble with home storage: 76.1%
- Trunk room usage experience rate: 22.6%
- Non-users who want to use if conditions are met: 53.4%
- Usage experience rate in Tokyo: 34.6%
While a lack of storage is a widespread lifestyle issue, trunk rooms may not yet be fully utilized.
Given the high intention to use among the non-user demographic, it is believed there is a certain level of potential demand in the market.
*Although the usage experience rate in this survey is high compared to the national household penetration rate of trunk rooms (about 1%), this questionnaire is an internet survey. Because it may include a certain number of respondents living in urban areas like Tokyo or those interested in storage services, caution is needed when simply comparing it with the national average.

The total trunk room usage experience rate nationwide is 22.6% (currently using 5.3%, past use 17.3%).
Establishment of "temporary use":
The ratio of past use is larger than current use, showing that trunk rooms are utilized as rental storage borrowed only for required periods, such as during moving or renovations.

On the other hand, regional differences are seen even in urban areas, with Osaka at 13.1% and Aichi at 14.3%.

Furthermore, looking at the family structure nationwide, single-person households (28.4%) top the list, but in Tokyo alone, nuclear families (40.9%) exceed single-person households (33.4%).
It can be said that there is a high demand for trunk room usage, mainly among families, in response to the lack of storage unique to urban areas.
