Full “Skeleton” Renovations

A “Skeleton” renovation is the ultimate way to modernize an older Japanese property. We strip the unit down to its concrete or wooden frame, allowing for a complete reconfiguration of the floor plan.

  • Total Re-piping & Wiring: Replacement of aging plumbing (polyethylene) and electrical systems to meet modern safety standards.
  • High-Performance Insulation: We install advanced thermal insulation and vapor barriers to combat Japan’s humid summers and cold winters.
  • Energy-Efficient Windows: Specialized installation of dual-pane or low-E glass windows to improve the building’s thermal envelope.

Kitchen, Bath & Sanitary Upgrades

We partner with Japan’s leading manufacturers to provide “System Kitchens” and “Unit Baths” that maximize space and functionality.

  • Luxury Brands: We supply and install premium fixtures from LIXIL, TOTO, Takara Standard, and Panasonic.
  • Custom Cabinetry & Countertops: From stone finishes to anti-bacterial surfaces.
  • Wet Area Relocation: Expert plumbing modification to move kitchens or bathrooms to more open-concept layouts.

Interior Fit-outs & Finishing Materials

The final layer of your home defines its character. We offer a vast selection of high-quality Japanese materials known for durability and style.

  • Wallcoverings: We use functional wallpapers (cushion vinyl or fabric) from Sangetsu, Sincol, and Lilycolor, including anti-allergen and pet-friendly options.
  • Window Treatments: Professional installation of blinds, curtains, and motorized rail systems from TOSO and Nichibei.
  • Advanced Flooring: Selection of hardwood, engineered wood (high-scratch resistance), and “cushion floor” (CF) for wet areas.

Complex Repairs & Technical Problem Solving

We excel where other “reform” companies hesitate. Our team specializes in the technical “troubleshooting” of Japanese buildings.

  • Moisture & Mold Restoration: Deep-tissue building repair to address the effects of Japan’s high humidity and past water leaks.
  • Structural Stabilization: Reinforcement of load-bearing elements and earthquake-resistant “Seisaku” upgrades.
  • Soundproofing: Specialized floor and wall treatments for multi-unit mansions to ensure privacy and compliance with building association rules.

Partial Renovations & Small-Scale Repairs

Not every project requires a full teardown. We provide fast, efficient updates for homeowners and landlords.

  • Room Refresh: Fast wallpaper and flooring replacement for tenant turnovers.
  • Eco-Upgrades: Installing LED lighting systems, smart thermostats, and water-saving toilets (TOTO Washlets).
  • Accessibility (Barrier-Free): Installing handrails, removing floor thresholds, and widening doorways for elderly-friendly living.
