Ignorance of Tenant Rights Leads to Disputes

According to statistics from the National Consumer Affairs Center of Japan, there are approximately 13,273 consultations annually regarding disputes at the time of moving out of rental housing (Source: National Consumer Affairs Center of Japan, FY2023). Analysis of these consultations reveals many cases where tenants comply with management company requests without being aware of their own legal rights.

How the New Tool Works

The Rights Checker uses AI to determine what rights a tenant has simply by inputting contract details and move-out conditions.

Input Items

Tenancy period
Details of special clauses in the contract (e.g., presence of cleaning clauses, scope of restoration to original condition)
Details of damages pointed out at the time of move-out
Items and amounts claimed by the management company

Check Results

1. Assessment of Ordinary Wear and Tear

Based on Article 621 of the Civil Code (amended in 2020), the tool identifies items claimed that fall under ordinary wear and tear or deterioration over time. Discoloration of wallpaper due to sunlight, thumbtack holes, and marks from furniture installation are, in principle, the landlord's responsibility.

2. Assessment of Special Clause Validity

For special clauses such as "cleaning costs are the tenant's responsibility," the tool checks whether the validity requirements based on Supreme Court precedent (December 16, 2005) are met. For a special clause to be valid, the tenant must clearly understand its content and express their intention to bear the obligation.

3. Depreciation Check for Age-Related Deterioration

According to MLIT guidelines, the useful life of wallpaper is 6 years (Source: MLIT Guidelines). The tool determines whether the remaining value corresponding to the tenancy period is correctly reflected.

4. Organization of Items to Confirm

The tool lists items that should be confirmed with the management company, complete with guideline article numbers.

Difference from Conventional Diagnosis Function

While the conventional diagnosis function determined "whether the amount is appropriate," the Rights Checker systematically organizes "what rights the tenant has." It supports not only the assessment of monetary appropriateness but also the fundamental determination of whether there is an obligation to pay at all.
