【Full Reveal】The Terrifying Property Tax Has Arrived! The Real Maintenance Costs of a Brand New Motorcycle Factory and a 30-Year-Old Log House

Hello, I’m Decoboco.
It’s been quite a while since I moved to the outer Boso region of Chiba Prefecture and started my long-awaited “log house living” and “motorcycle maintenance in a dedicated factory.”

And then it finally arrived in my mailbox. That “blue (or white) envelope.”
Yes, the property tax assessment notice.

This time, to serve as a reference (or a reality check) for those considering relocation or factory construction,
I’m fully disclosing the details that arrived!

1. The “Mercy” of a 30-Year-Old Log House

First, there’s the 30-year-old log house that serves as my residence. The assessed value here is approximately 2.2 million yen.

Thirty years is “character” for a building, but tax-wise it’s a “stable period with depreciation fully applied.”
The residential land exemption is working nicely too, and

honestly, it was a wallet-friendly amount—”well, this is about right.” Up to this point, things were peaceful.

2. The “Initiation” of the New Factory Bares Its Fangs

The problem is the sparkling new factory next door. When I opened the details, I did a double-take.

• Building (Factory) Assessed Value: Approximately 8.55 million yen
• Use: Factory (No exemptions!)

Here’s the lesson I want to share with everyone.
“Factories allow no mercy like residential properties do.” That’s the reality.

Residential properties get tax breaks like “half the tax in the first year,” but
independent “factories” get no such treatment.

The full tax rate hits the assessed value hard.

How Land Tax Becomes “Several Times Higher” for Non-Residential Use

Adding insult to injury is the land itself.
The portion of land designated for the factory is classified as “non-residential land (other land),”

• Residential land: The assessed value is reduced to 1/6
• Factory land: No exemptions! (There’s burden adjustment, but it’s several times higher than residential)

As you can see in the image, multiple parcels of land combined with a “business use” designation caused the land tax to skyrocket. Building a factory next to the log house came with a price: “the land tax won’t be reduced either”—a double blow.

Looking at This Tax Bill from a Motorcycle Mechanic’s Perspective

Looking at this total amount, honestly, it’s the kind of number where I think “I could’ve bought that expensive tool set…” or “How many carburetors would I need to overhaul to pay this?”

It’s different from my days in Meguro (Jonan district)—owning vast land and facilities has made me acutely aware of the “weight” of responsibility.

Summary: This is the “admission fee” for doing the best work possible

While the amount alone is “terrifying,” this notice is also proof that I’m here, running my own factory, and taking my shot.

• To those considering relocation + independence: Don’t forget to factor this “property tax without exemptions” into your running costs alongside construction expenses.

Sighing won’t make the taxes go down.
I’ll tape this notice to the garage wall (just kidding) and keep building engines with energy tomorrow!
