A precision-machinery parts maker wants a plant in Japan near its customers, while weighing Vietnam for a second line. Its question: lease a ready-built factory (RBF) and start producing immediately, or take a long land lease and build to spec? In Japan, the answer is dominated by a factor absent in Vietnam: earthquake standards — building a quake-compliant plant in Japan costs far more and takes far longer than leasing ready space.
1. Vietnam: two clear doors, bundled procedures in parks
- Ready-built factories: lease from park infrastructure developers or industrial-property developers (Decree 35/2022/ND-CP) — move machinery in and produce, typically within weeks to months.
- Lease land and build: land lease (50 years max under Land Law 2024), construction permits, fire-safety approval, environmental assessment — usually 6–12 months before groundbreaking.
- Cost logic: RBF costs more per m²/month but needs no upfront capital; self-building wins long-term for stays over 10–15 years or bespoke designs.
2. Japan: earthquake standards decide the equation
- Self-building — expensive and slow: the Building Standard Law imposes strict seismic requirements (shin-taishin); industrial construction costs rank among the world’s highest, with lengthy local-government permitting.
- Long land leases (shakuchi): the common leasehold model; in prefectural industrial parks firms lease land then build — still fully subject to seismic standards.
- Ready-built factories: industrial developers lease quake-compliant ready space — the choice of SMEs and fast-entry projects; high rents but zero construction risk.
- The contrast: in Japan “build” is a technical (seismic) and approval-time problem, not just money; in Vietnam it’s mainly administrative procedure and capital.
3. Decision framework
- Producing within 6 months: RBF in both countries — in Japan it also dodges seismic-compliance risk.
- Specialized plants (cleanrooms, heavy loads): self-build; in Japan add 30–50% cost and time versus ordinary estimates for seismic standards.
- Two-legged strategy: many firms lease RBF in Japan to serve local customers while leasing land to build in Vietnam for large-scale production — combining speed and cost.
- Legal notes: in Japan scrutinize shakuchi renewal terms and site-restoration duties at expiry; in Vietnam check the park developer’s remaining lease term and planning status.

Frequently Asked Questions
1. What’s hardest about self-building a plant in Japan?
Seismic standards under the Building Standard Law — high costs and long approvals, the biggest barrier versus Vietnam.
2. How fast can RBF in Vietnam start producing?
Typically weeks to months — sign with the park developer, move machinery in, produce.
3. What is shakuchi?
Japan’s common land-leasehold model — firms take long land leases then build on the land.
4. When should I self-build instead of leasing RBF?
For bespoke designs (cleanrooms, heavy loads) with long horizons (10–15+ years) — self-building wins long-term.
5. What lease risks need attention in Japan?
Shakuchi renewal terms and site-restoration obligations at expiry — negotiate them upfront.
