Surviving Japan's 2024 Overtime Law: The AI and Grant Strategy for Construction Firms (Vol. 1)
This is Vol. 1 of a four-part series produced in partnership between ArchiX and Akane SR, a labor and social insurance consulting firm based in Osaka.
Japan's construction industry has been navigating one of its most significant regulatory shifts in decades. In 2024, overtime cap regulations that had applied to other industries were extended to construction, leaving many business owners in a difficult position: not enough staff to meet demand, but legally unable to ask people to work more hours.
"We want to bring in AI or better tools to handle the workload - but where does the budget come from?"
If that's where you are, there's something worth knowing. The Japanese government currently offers a range of subsidies specifically designed to support productivity-improving investments, including AI tools. This series maps out how construction firms can use those programs alongside ArchiX to solve both the efficiency problem and the funding problem at the same time.
Introducing Our Partner for This Series

Akane SR (Akane Social Insurance Labor Consultant Firm)
Mizuno-san from Akane SR's subsidy consulting division joins us for this series. Akane SR is a Osaka-based labor management firm with deep experience in HR compliance and government grant applications. Their focus is on building the systems and structures that help businesses grow, not just handling paperwork on their behalf.
AI Investment Is Not a Cost - It's How You Compete

ArchiX: Mizuno-san, thank you for being part of this. The pressure on construction firms right now is real. We're hearing it directly from our users: "we need to cut the time we spend on renders," "we simply don't have enough people." How does it look from your side?

Mizuno, Akane SR: It's the same story we hear from construction clients across the Kansai region. "We can't hire fast enough, but we can't run the sites we have with the people we have." The idea of just working harder to push through it has hit a wall. The regulations are real, and willpower alone isn't a business strategy.

ArchiX: That's exactly where AI comes in. One of our clients - a small construction firm - used to spend anywhere from several days to a few weeks producing architectural renders and initial client proposals. After adopting ArchiX, that same work now takes a few hours. Tasks that previously had to be delegated or outsourced are handled in-house by the same person who would have made the request.

Time reduction achieved by ArchiX users: from 14 days to 2 hours

Mizuno, Akane SR: That's essentially buying time at a fraction of the cost. And the good news is that there's government funding available to help make that investment.

ArchiX: Right - though the upfront cost is still a real barrier for smaller firms. Even when the ROI is clear, the initial investment can feel like too big a risk.

Mizuno, Akane SR: That's where the Ministry of Health, Labour and Welfare's subsidy programs come in - and this is something many business owners misunderstand. These aren't handouts for struggling companies. They're non-repayable grants that the government offers to firms actively improving their working environment and contributing to broader social goals like workforce reform. Receiving one is essentially government recognition that your firm is doing something meaningful.
AI adoption that reduces overwork and improves productivity is precisely the kind of initiative these programs are designed to support.
Getting the Foundation Right: Why Labor Compliance Comes First

Mizuno, Akane SR: There is one non-negotiable prerequisite: these subsidies are only available to companies that are in compliance with labor law. The funding comes from employment insurance contributions, so firms with unpaid overtime, missing overtime agreements, or other violations are simply not eligible - regardless of how good their AI investment plan is.
In construction especially, time and attendance management can easily become inconsistent when people are moving between sites. Before anything else, confirm these three things:
- Employment rules and regulations are current and accurately reflect actual practice
- Overtime agreements are up to date with recent legal changes
- The three statutory records (employment contracts, attendance records, wage ledgers) are properly maintained
Getting these in order takes time, but it also has a direct business benefit beyond subsidies - a firm with solid labor management is more attractive to job applicants, which matters a great deal right now. We handle the compliance side so business owners can stay focused on the strategic question: how to use AI to grow.
The Three Subsidies Worth Knowing About

ArchiX: So getting the labor environment in order is both the prerequisite for subsidies and an investment in recruitment capacity. That's a compelling combination. Which specific subsidies are most relevant for construction firms adopting AI?

Mizuno, Akane SR: Three programs are particularly well-suited for construction firms investing in AI tools:
The Three Key Subsidies (Covered in This Series)
Work Environment Improvement Subsidy (業務改善助成金): For firms that raise their internal minimum wage and invest in productivity tools like AI software at the same time. We covered this in depth in Vol. 2.
Work Style Reform Promotion Support Subsidy (働き方改革推進支援助成金): Supports firms creating the conditions for reduced overtime and increased paid leave - including through AI tools that enable time savings.
Human Resource Development Support Subsidy (人材開発支援助成金): Subsidizes training costs for AI-related skills. In FY2026, small and medium enterprises may also qualify for an additional equipment investment component covering 50% of AI tool costs up to 1.5 million yen.

ArchiX: So training subsidies and tool investment subsidies can potentially be stacked - meaning even more of the total cost gets covered.
What Can Go Wrong: The Three Most Common Application Mistakes

Mizuno, Akane SR: It's important to be clear that these subsidies are not guaranteed simply by applying. They require strict compliance with process and timing. Here are the mistakes we see most often:
Documentation inconsistencies. Attendance records that don't match wage records, employment contracts that don't reflect actual working arrangements - these are the kinds of gaps that aren't obvious until a professional reviews them, and they're enough to get an application rejected.
Missing deadlines. The process has hard deadlines at multiple stages: the initial plan submission, the implementation window, and the final application. A single day's delay at any of these points is grounds for rejection.
Acting in the wrong order. Purchasing equipment before submitting the plan, or starting training before the plan is approved, disqualifies the application. This is one of the most common reasons firms that apply on their own don't receive funding.

ArchiX: Investing in AI to fix a real operational problem, then missing out on funding because of a paperwork sequence issue - that would be a frustrating outcome for any business owner.

Mizuno, Akane SR: Exactly. That's why we work alongside clients through the whole process - not just preparing the paperwork, but making sure the business is in a position to receive the grant before the clock starts. Once the labor environment is solid, additional subsidies become accessible too. Done correctly, these programs become a genuine asset for long-term growth.
What This Series Covers
The 2024 overtime reforms present a real challenge - but also a clear forcing function to modernize. Firms that respond by investing in AI and getting their labor management in order will be in a significantly stronger position in two or three years than those that don't.
The path forward:
- Use ArchiX to cut design and proposal time dramatically
- Use Akane SR's support to access government subsidies that offset the investment cost
- Build the labor compliance foundation that makes both possible - and improves your ability to attract and keep staff
Subsidy timing matters enormously. Getting advice early, before you've taken any steps, is what makes the difference between a successful application and a missed opportunity.
Coming up in Vol. 2: A detailed breakdown of the Work Environment Improvement Subsidy - how it works, how much you can receive, and how to use it alongside ArchiX to raise wages without putting pressure on the business.
