Thinking about Urban Bears and the Vacant House Problem Before the Rainy Season

Usually, "bears" and "vacant houses" sound like two completely different topics, don't they?

Bear problems are about mountains and rural areas.
Vacant house problems are about real estate and inheritance.
I think many people mentally categorize them that way.

However, lately, I've been seeing more situations where these two are definitely becoming connected.
Today, with the rainy season approaching, I'd like to write about that.

I never thought I'd have to think about "burglars" and "bears" when dealing with vacant house measures...

Vacant houses during the rainy season easily become "places that are easy for wild animals to approach"

From the rainy season through the summer, the gardens of vacant houses change at an incredible speed.

Grass that was only slightly overgrown in early spring grows rapidly due to the rainy season's rain and temperatures. The branches and leaves of garden trees spread out.
Visibility around the building suddenly becomes very poor.

If people lived in the house, they would mow the grass regularly, but that can't be done with a vacant house. Because no one lives there.

As a result, it ends up in this state:

Garden grass and trees grow wild.
This makes it easier for animals to hide.
If there are fruit trees in the garden (persimmon, chestnut, plum, loquat, etc.), the fruit is left to rot, attracting animals.
Small animals enter through under the floor, broken doors, or open windows.
And from the outside, it looks like a "place where no one is."

This isn't just about bears; it's the same for wild boars, raccoons, and masked palm civets.
For the vacant houses I patrol, I also take measures against swallows and centipedes.

Unmanaged gardens, before you know it, become "places where animals find it easy to stop by."

What is often said is that "when it comes to vacant house measures, it's about dealing with the aging of the building."
The roof gets damaged, the outer walls fall off, there is a risk of collapse.

Of course, that is important, but from now on, if you only look at that, you might overlook significant risks.

The urban bear problem is not a story of them "coming down from the mountains"

The term "urban bear" has been appearing in the news more often lately, hasn't it?

Simply put, it is the problem of bears appearing in human living areas.
Animals that were originally from the mountains are appearing in residential areas and parks for some reason. Such situations are occurring all over Japan.

Previously, it was seen as a "story of rural areas near mountains," but now that can no longer be said.

The Ministry of the Environment publishes flash reports on bear sightings and human injury cases, and updates have continued as of May 2026.
The government's "Bear Damage Countermeasure Roadmap" outlines policies through fiscal year 2030, focusing not just on emergency responses when they appear, but also on creating environments that prevent them from entering human living areas, population management, and human resource development.

What I want to focus on here is that the national government's measures are shifting from "what to do with a bear that has appeared" to "creating an environment that keeps bears from approaching human living areas."

For example, clearing bushes on the border with human settlements.
Maintaining trees along rivers.
Reducing places where animals can move while hiding themselves.

This is almost the same concept as managing the exterior of a vacant house.

Tidy up the garden. Mow the grass and trim the trees. Improve visibility. Do not leave fruit unattended.

I believe the essence of the urban bear problem is not that "bears have come down from the mountains," but that "wild animals are entering places where human life has thinned out."
And one of those "places where human life has thinned out" is the vacant house.

Vacant houses become "gaps in the community," not just "buildings"

Let's change our perspective a little and organize this.

A house where no one lives creates a "gap" in the community.
The lights don't turn on.
The grass grows long.
Mail piles up.
No one notices if there are noises.
No one knows who is managing it.

This "gap" also becomes a security risk.
It also becomes a risk during disasters.
And it also becomes a risk for wild animals to enter.

A vacant house is not just an old residence.
If it is not managed, it gradually loosens the safety of the community.

Population decline progresses. Vacant houses increase.
Vegetation is left unattended. Fruit trees are not managed.
Signs of human presence fade.
Wild animals approach human living areas.

This flow is connected by a single line, isn't it?

Reading from the three perspectives of the field, the market, and business opportunities

From here, I would like to talk a little about "how this connects to your own work."

How will the field change?

In the field of vacant house management, checking "gardens, exteriors, and plantings" is becoming more important than ever.
Grass height, the condition of fruit trees, animal footprints and droppings, and gaps under floors or doors.
These check items should be included in standard checklists from now on.

Of course, vacant house managers won't be capturing bears.
But they can "discover abnormalities early and connect them to the necessary places."
I believe that will become increasingly important in the future.

How will the market change...

The demand for "vacant houses x wildlife countermeasures" will certainly expand from here on.

Work such as mowing, pruning, and cleaning has always been in demand, but by adding the context of "environmental maintenance for wildlife countermeasures," the background of the requests will change.

A request to "mow the grass" becomes a goal to "keep animals away."
If you can articulate this, the explanation of the services you provide should also change.

What kind of business opportunities are there?

Honestly, I haven't yet found a 'correct' model for this.
However, if we think about it industry by industry, I believe some movements like these might emerge.

Those in architecture, real estate, landscaping, and facilitiesmight be able to propose services under the angle of 'regular maintenance for wildlife control'.

Those in security and patrolcould add value by incorporating checks for animal activity into their patrol reports.

Owners are often unaware

What I feel when talking to vacant house owners is that the awareness that 'gardens carry the risk of attracting animals' has not yet fully permeated.

A persimmon tree that has been cherished since the parents' generation as a 'long-standing garden tree' might now be a 'feeding ground for wild animals'.
Even when told this, many people don't immediately grasp it.

Reaching out with a suggestion like 'Why not check it before the rainy season?' can be an entry point to lower the owner's psychological hurdles.
Instead of waiting until 'after deciding whether to sell or rent,' taking a small step like 'just the garden for now' is surprisingly easier to act on.

Points to check before the rainy season

For vacant house owners and those involved in management, I have summarized what you should check while there is still time.

What is the condition of the vegetation (grass on the property, overgrowth onto roads or neighboring land, visibility around the building)?
Are fruit trees being neglected? (If fruit is left to fall, it attracts animals.)
Are there any gaps in the building? (Under the floor, broken doors, windows left open, etc., which are easy entry points for small animals.)
Is there any leftover garbage or fertilizer on the property?
Have there been any reports of bears or wild boars in the neighborhood?

You don't have to try to do all of this perfectly right away, so let's start by just grasping the current situation.

So, in conclusion

The urban bear problem and the vacant house problem are actually quite closely related.
Various risks creep into places where human life has thinned out.
The structure is the same.

Now, before the rainy season, is a good time to pause and check your garden and the exterior of the property.

If you own a vacant house, please check the condition of your garden before this year's rainy season.
If you are entrusted with management, please add 'wildlife risk perspective' as an item to this year's checklist.

We are entering an era where small checks lead to regional safety.
