What Is Offshore Development? A Complete Guide for Japanese Companies

What Is Offshore Development? The Basics

Offshore development is the practice of delegating software or web system development to teams or companies in other countries. It allows businesses to reduce costs compared to domestic development while still accessing the technical talent they need, which is why more companies are adopting it every year.

Originally, offshore development was something large enterprises used for major system projects. Today it’s widely used by startups and mid-sized companies for everything from EC site builds to mobile app development.

The basic model is straightforward: requirements are defined on the Japanese side, the overseas development team handles design, implementation, and testing, then delivers the finished product. In most cases, a bridge engineer (someone fluent in both Japanese and the local language) sits between the two sides to keep communication on track.

There are two primary contract structures:

  • Lab model (dedicated team): A dedicated development team is contracted for a set period. Well-suited for long-term projects or ongoing development work.
  • Fixed-price model (project-based): A discrete project is commissioned at a fixed scope and cost. Better for shorter engagements with clearly defined requirements.

Which structure fits depends on the scale, duration, and nature of the development work.

The Advantages of Offshore Development

Significant Cost Reduction

The most obvious advantage is cost. Compared to Japanese engineer salaries, equivalent-skill engineers in Vietnam or the Philippines can typically be secured for 30–50% less. The larger the team, the more this gap compounds.

That said, “cheaper” does not mean “lower quality.” Technical education standards in Vietnam and India have risen sharply in recent years, and engineers in these markets track modern technology closely. The genuine value of offshore development is achieving cost reduction without sacrificing quality.

Addressing Japan’s Severe IT Talent Shortage

Japan’s domestic IT talent shortage is a real and worsening problem. The Ministry of Economy, Trade and Industry projects a shortfall of up to 790,000 IT workers by 2030. For companies that spend months recruiting and still can’t fill roles, or that aren’t getting applications at all, offshore development is a practical answer.

Faster Development Velocity

By taking advantage of time zone differences, you can structure development so work continues even outside Japanese business hours. Vietnam in particular (2-hour time difference) has significant working hour overlap with Japan, enabling real-time communication during the day while also allowing after-hours progress from the Vietnam side.

On-Demand Scalability

Need to add five engineers quickly? Reduce the team after a project wraps? Offshore arrangements allow team scaling at a pace that domestic hiring simply cannot match.

The Disadvantages - and How to Handle Them

Communication Barriers

Language differences are the biggest challenge. Nuances in specifications get lost, verbal explanations are misunderstood, assumptions go unspoken. These are common failure modes.

Mitigation: Invest in bridge engineer quality. Complement written specifications with wireframes and mockups. Visual communication closes gaps that text leaves open. At DEMETIO, Japanese-Vietnamese bilingual bridge engineers are embedded in every project to minimize misalignment from day one.

Quality Control Challenges

Remote code review and quality checks require deliberate process design. “Done” in a status update doesn’t always mean done to the standard you expected.

Mitigation: Document code review standards clearly. Build automated testing into the CI/CD pipeline. Use an agile delivery model with small, reviewable increments rather than long stretches between deliverables.

Cultural and Business Practice Differences

Japan’s culture of reading between the lines, communicating expectations implicitly, does not translate overseas. Vague instructions produce unexpected results.

Mitigation: Be specific. Replace “make it look good” with “match this design comp exactly” or “response time under 1 second.” Quantify expectations wherever possible.

Security Risks

Handing source code and customer data to an external party is a legitimate concern.

Mitigation: Execute NDAs as a baseline. Set up development environments behind VPN. Manage access permissions carefully. Selecting a partner with ISO 27001 or ISMS certification adds a meaningful layer of assurance.

Why Japanese Companies Keep Choosing Vietnam

For Japanese businesses, Vietnam has emerged as one of the strongest offshore partners. Here’s why:

Cultural proximity: Vietnam shares Confucian cultural values: respect for seniority, conscientiousness, attention to detail. Engineers here tend to understand project intent and work proactively, rather than executing only what’s literally specified.

Japanese language talent: Japanese is among the most popular second languages in Vietnam, and JLPT exam participation ranks among the highest in the world. This makes finding qualified bridge engineers easier, and keeps communication costs down.

Growing technical capability: Vietnam’s IT industry is on a steep growth curve, actively supported by government investment in technical education. Engineers proficient in modern stacks (React, Node.js, AWS) are increasing in number every year.

Cost-performance ratio: Rates run slightly below India while maintaining a level of Japan-market familiarity that India-based teams often lack. For EC development and Shopify builds specifically, Vietnam engineers with Japanese market knowledge can deliver work that requires less correction and re-work.

Using Offshore Development for EC and Shopify Projects

EC and Shopify development is one of the areas where offshore development works particularly well.

Why Shopify and Offshore Are a Natural Fit

Shopify is a global platform with technical documentation unified in English. Overseas engineers access the same information as domestic ones, so there’s no technical knowledge gap caused by language or geography. Shopify theme development and app development use globally common technologies: Liquid, React, Node.js. Vietnamese engineers are well-versed in these, and can handle everything from custom theme builds to full Shopify app development.

Where Offshore Works in EC Projects

  • New EC site builds: Design through implementation, payment integration, end-to-end delivery
  • Shopify migrations: Moving from other platforms with data migration and customization
  • Custom app development: Inventory management, order processing, CRM integrations - business-specific functionality that the App Store doesn’t cover
  • Ongoing operations and maintenance: Routine updates, bug fixes, and content changes handled at a predictable monthly cost

DEMETIO’s model combines a Vietnam-based development team with a Japan-side director who manages client communication, project direction, and quality oversight. Full Shopify development services, from Japan-market UI/UX optimization to complex backend integrations , are handled as a single package.

5 Keys to Making Offshore Development Work

From experience across many projects, these are the factors that consistently determine whether offshore development succeeds or fails.

1. Invest Heavily in Requirements Definition

The single most common cause of offshore failure is ambiguous requirements. Things that would be understood implicitly in a domestic context need to be made explicit for overseas teams. Screen designs, API specifications, and acceptance criteria should all be defined in writing before development begins.

Spending 20–30% of total project effort on upfront requirements definition typically cuts rework dramatically.

2. Choose Based on Bridge Engineer Quality

When evaluating offshore development companies, rate alone is a poor filter. The bridge engineer’s capability is often the deciding factor in project outcomes. Evaluate Japanese language ability, technical depth, and project management skill, not just hourly cost.

3. Start Small and Build Trust

Don’t hand a large project to a new partner on day one. Run a smaller initial engagement first to verify the team’s capabilities and communication style in practice. A two-to-four week trial period is the ideal minimum.

4. Define Communication Norms Early

Regular meeting cadence, which tools to use for which types of communication, reporting formats. Agree on these at project kickoff. Using shared tools like Slack, Jira, and Figma creates transparency that reduces the information gaps that derail remote projects.

5. Think in Terms of Long-Term Partnership

Rotating vendors project-by-project tends to optimize for the wrong thing. A trusted long-term partner who understands your product, your business context, and your market will provide better work at better cost over time, and will increasingly be able to propose improvements rather than just execute instructions.

Summary

Offshore development is a genuinely effective way to reduce costs, address talent shortages, and increase development velocity simultaneously. The challenges around communication and quality management are real, but manageable with the right partner and the right process.

For Japanese companies specifically, Vietnam stands out as a strong option: cultural affinity, Japanese language capability, strong technical growth trajectory, and favorable cost-to-quality ratio. In the EC and Shopify space, the combination of a globally standardized platform and Vietnam’s engineering talent is a particularly productive match.

DEMETIO operates with development based in Ho Chi Minh City and a business team in Japan, working together to deliver EC and web development projects for the Japanese market.
