Will There Be a Place to Live in Japan in 10 Years? 'Abandoned Houses as General Knowledge' to be Released on June 11, 2026

Tomoyuki Maruoka, CEO of Nexwill Inc. (Headquarters: Shimbashi, Minato-ku, Tokyo), which operates 'WAKEGAI', a problematic property purchasing business that provides one-stop solutions for real estate issues associated with inheritance such as closing up a family home, announces the publication of his book 'Abandoned Houses as General Knowledge' on Thursday, June 11, 2026.

"1 in 7 homes is abandoned" - Japan's worsening abandoned house problem

According to the Ministry of Internal Affairs and Communications' 2023 Housing and Land Survey, the number of abandoned houses in Japan has reached a record high of 9 million units.

The abandonment rate is 13.8%. This means that 1 in 7 houses is abandoned.

The background to the worsening abandoned house problem is closely related to population decline and aging.

As regional depopulation progresses, the increasing number of abandoned houses causes many problems.

In particular, abandoned houses that continue to be neglected deteriorate, potentially leading to building collapse, pest and animal damage, and even becoming hotbeds for crime.

In many cases, owners who fail to manage their properties are unaware that such damage is occurring.

Even if you think it doesn't concern you, depending on your blood relations, you may suddenly inherit a distant abandoned house one day.

Even if your family home is a rental or condominium, what about your grandparents' house or relatives' houses?

The abandoned house problem is now a problem that anyone can become involved in.

Turning abandoned houses from 'negative assets' into 'assets'

Deterioration, depopulated areas, non-rebuildable properties, shared ownership, leased land, subsoil rights, unregistered properties, leftover items...

These types of problematic properties have been difficult to circulate and have tended to be left unattended.

However, in recent years, there have been increasing examples of such properties being put back on the market or utilized for regional revitalization.

Our company has purchased over 1,000 problematic properties in total and is working to circulate them in the market.

This book provides a detailed explanation of specific examples of public-private collaboration in utilizing abandoned houses, methods for resolving problematic properties, and breakthroughs for solving the abandoned house problem, including our company's collaborations with local governments and sports teams.

About Nexwill Inc.

Our company purchases abandoned houses and problematic properties that are considered difficult to sell compared to general real estate, removes the 'problems' that make them difficult to handle and sell by organizing rights and other issues, and resells them.

Many people associate problematic properties with 'stigmatized properties' (accident properties), but there are actually other factors.

Examples include shared ownership where multiple owners exist due to inheritance, non-rebuildable properties that do not meet Building Standards Act conditions, and properties where inheritance has been repeated without registration, ultimately making the owner unknown.

Our company operates 'WAKEGAI', a problematic property purchasing business that purchases such properties, organizes rights, and makes them available for sale.

Furthermore, we are actively engaged in public-private partnerships with local governments and sports teams to solve the worsening abandoned house problem. We have concluded partnership agreements with multiple local governments to support solving abandoned house issues, and we are also collaborating with sports teams to promote the resolution of abandoned house problems and regional revitalization through a three-way partnership of 'local government x sports team x Nexwill'.
