Trunk Room Search "e-trunk" Publishes Editorial Policy and Evaluation Criteria - Aiming for an Environment Where Users Can Choose with Confidence by Clarifying Independence of Advertising and Evaluation -

e-portal Inc. (Headquarters: Shimbashi, Minato-ku, Tokyo; President: Masayuki Taniguchi), which operates the trunk room search and comparison service "e-trunk" (https://e-trunk.jp/), established and published its "Content Creation and Trunk Room Listing Policy" on June 23, 2026. This policy outlines the operational guidelines for content creation and trunk room listings.

This policy aims to create an environment where users can utilize information with greater peace of mind by clearly defining the editorial policy, evaluation criteria for comparisons and rankings, and the independence of advertising and evaluations.

Background of Establishment

Choosing a trunk room, storage unit, or container box involves many comparison items beyond just price and location, such as security, air conditioning, contract terms, and insurance. Currently, information is scattered among different providers.

To resolve this "difficulty in choosing" and enable users to make informed decisions, we have decided to clearly define and widely publish the principles and rules that e-trunk values in providing information.

Key Points of the Policy

Explicitly states 3 editorial policies: "User First," "Accuracy," and "Neutrality and Fairness" are established as the basic principles for content creation. The priority is placed on what is truly useful for users searching for space, not on the convenience of listed providers.

Publishes evaluation criteria for comparisons and rankings: It has been clarified that comparisons and displays are made based on pre-defined objective criteria such as price, location, security, and facilities.

Clarifies the independence of advertising/PR and evaluations: e-trunk is operated through listing fees and advertising placements from providers, but their presence or absence does not affect the evaluation, comparison results, or display order of articles. Content for advertising/PR purposes will be clearly marked as such.

Clarifies handling of property and provider information: Information such as prices and facilities for each property is provided through a system where the operating provider registers and updates it. Users are advised to confirm directly with each provider before finalizing their contract.

Correction of errors and inquiry system: We investigate指摘 from both users and providers and respond promptly if a correction is deemed necessary.

Future Outlook

Since the service began in 2007, e-trunk has been disseminating information about the trunk room industry for over 19 years and currently provides nationwide listing information.

Through the publication of this policy, we aim to further enhance the transparency and reliability of our information and strive to be a service where "all people struggling with storage can find the optimal space for them without hesitation."
