ITANDI Announces '2026 Rental Peak Season Competitive Areas Ranking' for Tokyo and Osaka

ITANDI Inc., a company dedicated to streamlining real estate transactions through technology, has analyzed statistical data on residential move-in applications via its real-time real estate brokerage site, 'ITANDI BB', and announced the 2026 rental peak season competitive areas ranking for Tokyo and Osaka.

◆ Overview
In recent years, the peak rental season has shown a trend of starting earlier. This is speculated to be influenced by changing lifestyles, such as moving earlier to avoid rising relocation costs, and the earlier confirmation of academic paths due to the increase in comprehensive university selection (formerly AO entrance exams).

This survey ranks 'competitive areas' during the 2026 peak season based on 'ITANDI BB' data. In this survey, 'competitive areas' are defined as those with active markets where many applicants gather, and where the period from property listing to the first application is extremely short, indicating a high speed of decision-making.

During the peak season, popular properties in metropolitan areas receive applications shortly after listing, forcing prospective tenants to decide within a limited time. With slight delays in information gathering or responding to applications directly impacting the success of a contract, real estate brokerage teams are required to act with speed.
