The story
A Nikkei BOOK Plus article about a 37-year-old female site supervisor at major general contractor Obayashi Corp, who broke the ¥10 million (roughly $67,000) annual salary mark by earning the trust of the tradespeople she works with, sparked discussion on 5ch’s News Express+ board. Site supervision at a major contractor is a job that hinges on communication skills with on-site craftsmen, and the article credits her success to a collaborative style — listening closely and working things out through dialogue rather than simply steamrolling workers with “just do it.” The thread debated the salary figure itself, with some calling ¥10 million at age 37 “cheap for a major firm in this day and age” and others saying she got there “10 years too late,” while others questioned whether the pay truly matches the brutal workload of the job. Some also pointed out that site supervisor roles are often filled by highly educated hires, including graduates of architecture-related graduate programs.

What people said
They're a mega-major firm, you know
Re: #21
I mean, isn't her role not even the one dealing directly with the tradesmen anyway?
¥10 million as a site supervisor at a major general contractor isn't exactly a dream job, is it
10 years too late
Yeah right, lol
are highly educated, you know
they're not your average construction laborer
and their real grind doesn't even start until 5pm (once the site closes, the desk-work begins)
Well yeah, she's a grad school graduate in architecture/construction engineering
Anyway, isn't ¥10 million in Tokyo not that impressive?
You're in your 70s, aren't you
and let me tell you, those supervisor jobs are genuinely brutal
A regular site laborer would never get anywhere near this
Jobs like this are the ones that'll survive
Honestly, couldn't AI handle directing the job site too?
Oh? There's a horsetail shoot growing right here. (a stock 2channel meme phrase used to mock an out-of-place comment)
and only gets ¥10 million?
It's the finance industry overall that's raking in too much
Aren't they just some company burying pipes and paving roads out in the sticks somewhere?
They're the company that built the Tokyo Skytree and is working on a space elevator
They also put up that pole called the Tokyo Skytree out in the boonies known as Tokyo
My cousin worked at a general contractor
went through three grad schools on the company's dime
when I asked what he was even doing, he said stuff like
giving presentations at academic conferences
¥6 million
Site management's annual salary: ¥10 million (lol)
Ridiculous
You're underestimating modern workers
Getting ¥6 million just for slapping on plaster all day is the actually abnormal part
If you think that, go graduate from a national university, squeeze through the narrow gate, and land a new-grad job at Obayashi
Site supervisors at Obayashi's level are basically elites
Background and Key Points of This Discussion
Site supervisors (construction management roles) at major general contractors handle negotiating with tradespeople, safety management, and schedule coordination all at once. As labor shortages and an aging workforce spread across the construction industry, interest is growing in dialogue-based management over top-down, command-style approaches. The female supervisor featured in this story is one example of that shift. Where opinions split in the thread was over how to evaluate the ¥10 million figure itself: some argued it’s low compared to incomes in other urban industries, while others felt reaching that amount by age 37 was actually fast — reflecting differing views on how to weigh the age of attainment against the weight of the job’s responsibilities. It’s also easy to miss from the article alone that, despite being widely seen as manual labor, the role actually requires qualifications like a certified construction management engineer license and a technical education background. Japan’s Ministry of Land, Infrastructure, Transport and Tourism has also been pushing to promote greater roles for female engineers and skilled workers in construction, and this article appears to have been picked up as part of that broader trend.
