Palma Co., Ltd. Delivers Lecture at Study Session Hosted by Japan Rental Box Association

Palma Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Junichi Kimura) delivered a lecture on the theme of "The Current Situation of the Trunk Room Industry" at a study session hosted by the Japan Rental Box Association on March 27, 2026.

This lecture was held as the first part of a study session targeting member companies of the association, with Mr. Takashi Shimomura, Executive Officer and General Manager of the Business Strategy Division, taking the stage. He shared the latest market trends and insights from a practical perspective with industry stakeholders.

**Key Points of the Lecture** ~The Reality of the Industry Seen from Market Growth and Practical Data~ This lecture explained the current situation and changes in the trunk room industry based on the following themes:

- Growth and expansion trends of the self-storage market - User trends and market conditions seen from Palma's data - Customer acquisition and marketing data for our own brand "Keypit"

The domestic self-storage market has steadily expanded over the past approximately 10 years and is in a growth phase as an industry. Within this, our new application requests have increased by approximately 196% compared to 10 years ago, and the cumulative outstanding guarantee balance has increased from approximately 58,000 cases to 135,000 cases, an increase of approximately 231%, confirming the rising demand linked to market expansion. In this lecture, we presented insights based on actual field data in addition to these overall market movements.

**High Interest as a Venue for Sharing the "Now" of the Industry** On the day, many industry stakeholders, mainly self-storage operators, participated, and a practical exchange of opinions took place during the Q&A session after the lecture, reflecting the high level of interest in the industry. The Japan Rental Box Association, which hosted this study session, was established with the aim of ensuring the safe and sound development of rental box businesses such as containers and trunk rooms. Currently, it has 42 regular member companies and 21 supporting member companies. Through regular meetings by directors and study sessions/social gatherings for all members, it provides a venue for information exchange and collaboration not only among peers but also with related businesses, contributing to the development of the industry. Palma actively participates in such initiatives and continues to disseminate information that contributes to the overall advancement of the industry.

**Future Outlook** While the trunk room market is expected to continue expanding, the demands on operators are expected to become even more diverse, such as the sophistication of operations and changes in customer acquisition methods. As an infrastructure company for the industry, we will continue to support the growth of operators from both data and service aspects and contribute to the development of the self-storage market.
