Hello, everyone.

This is Enta.

The other day, I wrote about the standard amounts used in the construction industry.

 

There are some construction companies that attract people by promoting things like “support for starting your own business,” aren’t there?

The idea is to have them join a company for a while (as a sole proprietor) so they can eventually go into business on their own,

Is this a system where they say, “Since you want to go independent, work for us cheap for now, and once you’ve learned the ropes, you can go independent”? lol

In exchange, are they making you sign some kind of contract that prevents you from going independent without permission? Or something like giving priority to subcontracts from that company?

There used to be things like that back in the day, but I wonder if they still exist today??

In this post, I’d like to compare the salaries of salaried workers and self-employed craftsmen.

I’ll try to explain this in a way that’s easy to understand, especially for those who want to become self-employed.

① Salaried worker with an annual income of 5 million yen

"Employee Copay" and "The Amount the Company Actually Pays"

Prerequisites

• Annual Income: 5 million yen

• Association Health Insurance

• Under 40

• Assuming single status

---

🔹 Out-of-pocket expenses (deductions you can see)

👉 Take-home pay is approximately 4.26 million yen (excluding taxes)

---

🔹 Company-Paid Portion (A Little-Known Fact)

---

🔥 The total amount the company actually pays

5 million yen + approximately 770,000 yen = approximately 5.77 million yen

In other words
👉 Employee with an annual income of 5 million yen = Company's total cost: approximately 5.8 million yen

---

② For regular employment (daily rate of 35,000 yen)

Annual Income Simulator

Prerequisites

• Daily Rate:35,000 yen

• Operational:Monday, the 22nd

• Annual:264 days

35,000 yen × 264 days = 9,240,000 yen

👉 Annual income: approximately 9.24 million yen (gross)

---

🔹 Out-of-pocket expenses (National Health Insurance + National Pension)

*Regional variations apply; this is a rough estimate of what’s realistic.

---

🔹 Perceived Take-Home Pay

👉 Feels like about 1.8 times the take-home pay of a typical office worker

*However,

• No paid time off

• If I take a day off, my income drops to zero.

• Illness or Injury = Immediate Loss of Income

④ “Ultra-Realistic Conclusions” for the Construction Industry

Office Worker

• Stability
• Actually,The company is paying me quite a bit.
• Retirement is relatively easy
• All machinery and tools belong to the company
• These days, if you work for a small or medium-sized business and are energetic and qualified, you can keep working indefinitely.
• Young people are foreigners
• I get paid even if I don't have any work
• “Daily wages are your ”current pay,“ while social insurance is your ”future pay.'"

Common

• The Strongest Right Now
• All machinery and tools are my own
• Insurance and everything else are your own responsibility.
• You need a certain level of scale to employ foreign workers.
• Freedom
• Their cash reserves are overwhelming(However, if you don't take the initiative to plan for your pension, insurance, and retirement, you're in trouble.)
• Getting sick is seriously bad.
• Constantly bearing the above risks

I’m comparing this strictly to regular employment, but since this is an area where self-employed individuals often stand out, here’s a rough comparison.

I think there’s no greater dream than this, since sole proprietors who start by building a team from here and obtain a construction business license have the potential to take on even larger projects.

What do you all think?

Next time, I'm thinking of writing about office workers and starting your own business.

See you later.
