Understanding Rental Price Conflicts: A Free Seminar by SA Corporation

Free Seminar: Understanding Rental Price Conflicts



On June 21, 2025, SA Corporation, headquartered in Chiyoda-ku, Tokyo, will hold a complimentary seminar addressing the increasing rental price troubles and management chaos plaguing the real estate industry. The seminar is titled "Exit Strategies in the Era of Rental Increases and Short-Term Rentals: Insights from Real Estate Appraisal."

Recent events, including reports of rental notifications soaring by 2.5 times, have highlighted urgent concerns in urban areas about rental prices and management difficulties. During this seminar, real estate appraisers will analyze cases where rents have unexpectedly surged due to failed management practices, neglect during owner changes, unilateral rent hikes, and conversions into unregistered short-term rentals.

Experts will answer pressing questions like:
  • - How is the "fair price" of rent determined?
  • - Is it legal for rent to increase more than double?
  • - What action should one take if the landlord does not respond to formal notices?
  • - Can rental terms be altered unilaterally after management changes?
  • - How should residents react if their properties are repurposed for unauthorized rentals?

In recent years, the crisis of soaring rental prices has escalated, especially in older apartment buildings where rents have suddenly increased up to 2.5 times. Many residents find themselves feeling powerless and unsure of how to respond. While it might seem that rents are naturally set by the market, the reality involves specialized processes, including appraisal, negotiation, and mediation.

SA Corporation has developed a comprehensive exit strategy that includes collaboration among real estate appraisers, negotiation supporters, and practical management experts. This strategy encompasses assessing rent fairness, responding to unilateral notices, redesigning contracts, and assisting the elderly with transitional housing needs.
