Professional support for construction, renovation, and fit-out projects across Japan.

Even if your project is located outside the Tokyo / Saitama / Kanagawa / Chiba area, Ai Construction can support you through our Nationwide Construction Advisory Service.

As a licensed construction company, real estate company, and First-Class Architect Office, we guide both business clients and individual homeowners through every stage—no matter the region.

1. Local Contractor Matching & Screening

We help you find reliable local builders, especially in cities and regions where we cannot directly handle construction.

• Screening of 2–3 contractors
• Reviewing licenses, track record, and quality
• Checking past projects and reputation
• Introducing the contractor most suitable for your needs

2. Plan, Cost, and Feasibility Review

Before you decide, we review:

• Floor plans, design drawings
• Renovation feasibility
• Local building rules & restrictions
• Budget ranges by region
• Risks or complications you should know

We provide clear explanations in English/Japanese, so you can make decisions with confidence.

3. Owner’s Representative Support

If you cannot visit the site often or live overseas, we can act as your client-side representative.

• Attend online/onsite meetings with contractors
• Review quotations & construction specifications
