Japan has one of the richest woodworking traditions in the world. Temples raised without a single nail, houses framed with hand-cut joints and modern homes assembled from precision pre-cut timber all depend on the same figure: the daiku, or carpenter. Yet the trade is shrinking fast. National census data compiled by the land ministry shows the number of carpenters falling from roughly 650,000 in 2000 to about 300,000 in 2020, with the share aged 60 or older climbing from about one in five to over four in ten.
That shortage has opened a door for foreign workers, mainly through the building category of the construction Specified Skilled Worker system. This guide looks at the different kinds of carpentry work in Japan, the residence routes that apply, the national trade test, what carpenters earn in yen, how apprenticeship really works, the tools you will need and the safety rules that matter most on a timber frame.
Three Kinds of Carpenter on Japanese Sites
The word daiku covers several quite different jobs. Knowing which one an offer describes will tell you a lot about the pay, the hours and the skills you will build.
Wooden House Carpenters (Mokuzo Daiku)
Most detached houses in Japan are still built with timber, using a post-and-beam method. House carpenters erect the frame on the foundation, fix floor joists, rafters and roof boards, install wall panels and windows, and often complete much of the interior. On the day the frame goes up, called the jotoshiki, a whole crew raises the structure in a single day.
Formwork Carpenters (Katawaku Daiku)
Formwork carpenters build the temporary wooden or panel moulds into which concrete is poured for foundations, columns, walls and slabs. The work is heavy, fast and tied to concrete pouring schedules on apartment blocks, offices, bridges and other large structures.
Interior Finishing Carpenters (Naisou)
Interior carpenters install light-gauge steel or timber stud walls, ceilings, plasterboard, flooring, door frames and fitted furniture inside shops, offices, hotels and apartments. Renovation work is a large and growing share of this segment.
From Hand Joinery to Pre-Cut Factories
Traditional carpenters marked and cut every joint by hand, reading the timber and calculating roof angles with a geometric method called kikujutsu. Today, the great majority of house frames are cut in pre-cut factories, where computer-controlled machines shape beams and posts to the design drawings. The frame then arrives on site ready to assemble like a large kit.
This shift has two effects for newcomers. First, factory jobs operating or feeding pre-cut machines exist in many regions and can be an entry point into the timber world. Second, site carpenters now spend more time on assembly, fixing hardware, insulation and finishing than on hand-cut joints. Hand joinery survives in shrine and temple work, high-end custom homes and restoration, but those roles usually go to people with many years under a respected master.
Getting Permission to Work: Residence Routes for Carpenters
Ordinary tourists cannot work in Japan, so you will need a residence status that covers construction. Foreign carpenters commonly come through one of three paths.
- Specified Skilled Worker (SSW), construction field. The main skilled route for site carpentry.
- Technical Intern Training. Interns are placed in construction trades such as carpentry and formwork. This programme is expected to give way to the Employment for Skill Development system, called Ikusei Shuro, around April 2027.
- Statuses with no work limit. Permanent residents, spouses of Japanese nationals and long-term residents can join any carpentry firm that will hire them.
The paperwork runs in the usual order: a Certificate of Eligibility arranged by the employer in Japan, a visa issued by the Japanese embassy or consulate, then a residence card when you arrive.
Where Carpentry Fits in the Building Category
Within construction SSW, work is grouped into civil engineering, building, and lifeline and facilities. Carpentry belongs to the building category, which industry guides describe as including trades such as carpentry, plastering, roofing, tiling, interior finishing and waterproofing, along with related tasks. Formwork has been listed by some guides under civil engineering rather than building, because it supports concrete structures, so a formwork carpenter should confirm the exact category before choosing which test to take.
Tests and Language
For SSW (i), candidates generally pass a construction skills evaluation test matching their category and a Japanese test, usually JFT-Basic or JLPT N4. The total stay limit for SSW (i) is five years. Former technical interns who completed their training in a related trade may be exempt from some testing; check current rules.
Moving Up to SSW (ii)
Construction is among the fields offering SSW (ii), which is aimed at experienced workers who can supervise a team. It can be renewed without a fixed upper limit and may allow your family to live with you. Requirements can shift, so confirm the latest conditions with the Immigration Services Agency of Japan.
Kenchiku Daiku Ginou Kentei: The National Trade Test
Japan’s national trade skill testing system, ginou kentei, includes a building carpentry test called kenchiku daiku. It is generally offered at 1st, 2nd and 3rd grade, and people who pass the 1st or 2nd grade may call themselves a certified skilled worker, or ginoushi.
The test usually has two parts: a written paper on materials, tools, construction methods, drawings and safety, and a practical task in which candidates mark out and cut timber joints to a drawing within a time limit. Higher grades typically require several years of practical experience before you can sit them, while the 3rd grade is aimed at beginners and trainees.
The certificate matters because employers, clients and immigration reviewers all treat it as solid proof of skill. For a foreign carpenter, a 2nd-grade pass can strengthen a pay negotiation and may support progress toward SSW (ii). The test is held in Japanese, so learning trade vocabulary early pays off.
Carpenter Pay in Japan: Typical Yen Ranges
Earnings vary with region, specialism, firm size and how many working days a month a crew actually gets. These are rough figures before tax and social insurance.
| Carpentry Role | Typical Pay (Yen) | Status or Requirement |
|---|---|---|
| Apprentice / helper | ¥170,000 to ¥230,000 a month | Intern, SSW (i) or open status |
| Pre-cut factory operator | ¥190,000 to ¥260,000 a month | Open status or manufacturing route |
| House carpenter, day rate | ¥14,000 to ¥22,000 a day | Experience; own hand tools |
| Formwork carpenter | ¥14,000 to ¥20,000 a day | SSW construction or open status |
| Interior finishing carpenter | ¥220,000 to ¥320,000 a month | SSW building category or open status |
| Certified carpenter (ginoushi) | ¥260,000 to ¥380,000 a month | 2nd or 1st grade kenchiku daiku |
| Crew leader (shokucho) | ¥320,000 to ¥450,000 a month | Long experience; often SSW (ii) |
| Independent contractor | ¥20,000 to ¥30,000 a day | Unrestricted status; own tools and insurance |
The yen ranges in this table are approximations only, and real earnings depend on the prefecture, the firm, the season and your own skill level. This article is shared as career information. It is not an offer of work, and we are not a recruiter, job broker or immigration adviser. Please check every condition with the hiring company, confirm residence rules with the Immigration Services Agency of Japan, and use Hello Work or the Ministry of Health, Labour and Welfare to verify labour standards.
Nikkyu Pay and What It Means for Your Month
Many carpenters, especially in small firms and among experienced tradespeople, are paid a daily rate. On paper, a day rate of ¥18,000 looks generous. Multiply it by 22 working days and it is excellent. Multiply it by 15 days during a rainy month or a gap between houses and it is far less impressive.
When comparing offers, ask how many days a month the crew typically works, what happens on rain days, whether travel time to distant sites is paid, and whether social insurance is included. For SSW construction workers, the rules generally expect stable monthly pay at least equal to that of a comparable Japanese worker, so a pure day-rate offer to an SSW holder deserves careful questions.
Learning the Trade Under an Oyakata
Carpentry in Japan is still taught largely by example. A newcomer joins the crew of an oyakata, the master carpenter who runs the team, and starts with sweeping shavings, carrying timber, sharpening tools and handing materials up the scaffold. Explanations can be brief. You are expected to watch closely, ask at the right moment and remember what you are shown.
This style can feel hard at first, but it also builds real skill and trust. Some regions also run carpentry training schools and vocational courses, and larger house builders operate in-house training programmes. Whatever the setting, patience, punctuality, a tidy work area and respect for tools earn you more responsibility faster than anything else.
Your Tool Kit: An Investment That Grows
Japanese carpenters are known for their tools: pull saws, chisels, planes, marking gauges, the carpenter’s square called a sashigane and, today, a full set of cordless power tools. Many crews expect workers to bring their own hand tools, and in some firms that extends to power tools as well.
- Starter set. Expect to buy a tool belt, hammer, tape measure, square, utility knives, a few chisels and a saw in your first months.
- Power tools. Impact drivers, circular saws and nail guns are costly, so ask whether the company supplies them or offers a tool allowance.
- Maintenance. Sharpening on whetstones is a skill in itself and a daily habit for serious carpenters.
Never accept an arrangement where an employer deducts large, unexplained tool charges from your pay. Deductions from wages generally need a proper written agreement.
Safety at Height and on the Frame
Falls are among the leading causes of death in Japanese construction, and carpenters work on roofs, upper floors and scaffolding every day. Full-body harnesses are now the standard expectation for most work at height, and special safety training is required before using them in certain situations. Your employer should provide this.
Other common hazards include nail-gun injuries, saw cuts, falling materials during the frame raising and heatstroke in summer. Morning safety meetings, the KY danger prediction exercise and pointing-and-calling checks are routine. If a task looks clearly unsafe, you can raise it with the site manager, and serious problems can be reported to the labour standards inspection office. If you are hurt at work, make sure the injury is reported so workers’ accident insurance applies.
Working Hours and Wage Protection for Carpenters
Under the Labour Standards Act, standard hours are 8 a day and 40 a week, and overtime beyond that is generally paid at a premium of at least 25 percent. Since April 2024, construction has been subject to the legal cap on overtime hours, with limited exceptions for disaster recovery work.
Minimum wages are set prefecture by prefecture. The national weighted average in fiscal 2025 was ¥1,121 an hour, and the fiscal 2026 rates came into force between October and early December 2026, with Tokyo near ¥1,280 and the lowest prefecture a little above ¥1,080. Employees are normally enrolled in health insurance, the employees’ pension and employment insurance. Be careful with offers that label you an independent contractor from day one; in that case you may lose overtime pay and insurance coverage.
Language and Paperwork on a Timber Site
Carpentry vocabulary mixes everyday Japanese with old trade terms for joints, timber grades and measurements, including traditional units like the shaku and sun that still appear on some drawings. Study the names of common materials, joints and tools, and practise reading floor plans and section drawings. JLPT N4 may satisfy the SSW requirement, but aiming higher will make the trade test and promotion much easier.
Ask your employer to register you in the industry’s career record system so that your site days and qualifications are logged, and keep your own notebook of projects, dates and skills learned.
Warning Signs in Carpentry Offers
- Brokers charging heavy fees for a construction placement or promising guaranteed SSW approval.
- Contracts only in Japanese with no explanation in a language you understand.
- Employers wanting to keep your passport or residence card.
- Day-rate offers with no clear answer about rain days or insurance.
Building a Life One Beam at a Time
Carpentry in Japan combines a deep craft heritage with a very modern labour shortage. For foreign workers, the most realistic start is the building category of construction SSW or an unrestricted residence status, followed by years of learning on site, steady Japanese study and a run at the kenchiku daiku trade test. With an ageing workforce and endless renovation demand, skilled hands that arrive now may find themselves leading crews in the years ahead.
Carpentry Questions Readers Ask Before Moving
Is formwork the same as house carpentry in Japan?
No. Formwork carpenters build concrete moulds for larger structures, while house carpenters frame and finish timber homes. The skills overlap only partly, and the SSW category and test can differ, so confirm which one your job falls under.
Will my carpentry experience from home count?
It helps you learn faster, but Japan generally does not convert foreign trade certificates. You will usually need to pass the relevant SSW skills test, and the national ginou kentei if you want formal recognition.
Do I have to buy all my own tools?
Often you will buy at least basic hand tools. Practices vary widely, so ask whether the firm supplies power tools, pays a tool allowance or lends equipment during your first year.
