Hello, everyone.
This is Enta.
We have recently renewed our construction business license.

I've been working on it since around October, and I finally finished registering at the end of February lol
The reason for this is the existence of the sales office.
Actually, I think I mentioned this before, but we opened a sales office in Hamamatsu City, Shizuoka Prefecture, last year.
Since we were told that we would need to renew our permit to open a branch office, we opted for a ministerial permit.

Now I can go out and do business with my head held high lol
Since I think there are some people who don’t fully understand construction business licenses, I’ve summarized the information below.
🔨 Basics of Construction Business Licenses
A "construction business license" is required to operate a construction business.
This permit can be broadly categorized into the following types:"Who Gives It to You?" と "What kind of construction work is it?" It can be categorized based on these two perspectives.
🏛 Who gives it to you:Ministerial Approval vs. Governor's Approval
| Category | Contents | 例 |
|---|---|---|
| Ministerial Approval | Required when a company has business offices in two or more prefectures. | Companies with sales offices in Aichi and Shizuoka, etc. |
| Governor's Approval | Required when a business has offices only within a single prefecture. | Companies with offices only in Aichi Prefecture, etc. |
*Note: A “business office” refers to a location where practical business operations, such as contract management, are carried out. A simple warehouse or job site is not considered a business office. (I just learned this for the first time lol.)
🏗 What kind of construction work is it?:General Construction Business vs. Specific Construction Business
| Category | Contents | Requirements | Eligible Construction Projects |
|---|---|---|---|
| General Construction Business | The amount paid to subcontractors isLess than 40 million yen (less than 60 million yen for turnkey construction projects) | None in particular | Small-scale construction projects, even those with a general contractor, but involving small amounts |
| Designated Construction Business | The amount paid to subcontractors is40 million yen or more (60 million yen or more for turnkey construction projects) | Strict financial criteria (net assets, accumulated losses, etc.) | Large-scale construction projects; general contractors that rely heavily on subcontractors |
🧾 How to Read a Permit Number (Example)
In our case
This means:
- Minister of Land, Infrastructure, Transport and Tourism: Ministerial Approval (i.e., has business offices in multiple prefectures)
- 特: Specified Construction Business
- General: General Construction
- 6: Year of License (Renewal) in Reiwa 6
- No. 29472: Individual numbers (nationwide)
In other words, there are a total of 4 types !
-
Ministerial Approval · General
-
Ministerial Approval/Designated
-
Governor's Permit · General
-
Governor's Approval · Designated
At our house,This time, we changed it from 3 to 1.That's the point.
In reality, nothing has changed at all, and I intend to continue working as a subcontractor for the general contractor, carrying out slope stabilization and anchor installation work.
To all civil engineering contractors in Hamamatsu!
Once again, I’m new here, but I look forward to working with you all.
I don't take on any prime contracts, but please let me be a full-fledged subcontractor lol
If you just said, “Come say hi first!” I’d be right there in a flash lol
(I'm too busy to go right now, lol)
Even if that's not the case, I'll probably get in touch and stop by sometime, so when I do, please don't brush me off—let's at least have a chat... lol
See you later.
