"I want to live in a traditional Japanese house," "What should I do with the kominka I inherited?" These are common reasons people choose kominka renovation. This approach, which restores a home to modern living standards while preserving the character of a traditional kominka, is also drawing attention from the perspectives of tax efficiency and asset value. In this article, we organize the appeal of kominka renovation and the key points to watch.
What Is Kominka Renovation?
A kominka refers to an older private house built using traditional construction methods. Typical features of traditional Japanese construction include exposed heavy beams and columns, as well as wooden joinery that connects materials without metal fittings at the joints.
Kominka renovation refers to renovation work that preserves the appeal of these traditional structures and design details while upgrading insulation, seismic performance, plumbing areas, and building systems to modern standards. By making use of the existing building rather than rebuilding from scratch, owners can create a distinctive spatial value.
What Makes Kominka Renovation Appealing?
You can combine traditional atmosphere with modern amenities
Open atriums, earthen-floor spaces, engawa verandas, and ceilings with exposed beams - these spaces unique to Japanese houses offer a one-of-a-kind appeal that is difficult to reproduce in a newly built modern home. By taking advantage of the kominka structure and combining it with a modern kitchen and bathroom, it is possible to achieve both comfort and character.
In some cases, property tax can be reduced
Compared with rebuilding, kominka renovation often keeps property tax lower. Depending on the age of the building, property tax may already be reduced, and the change in assessed value caused by renovation may also be more limited than with a full rebuild.
What Should You Watch Out for in Kominka Renovation?
Cold-weather measures are essential in winter
Traditional Japanese houses were designed with ventilation in mind, so their insulation performance is low and they can become extremely cold in winter. Please consider full-floor heating, high-performance insulation, double-glazed windows, and other cold-weather measures as priorities in the renovation plan.
Always inspect seismic performance and building deterioration
In most cases, kominka were built before current seismic standards were established in June 1981. Because structural reinforcement work and repairs for leaks and plumbing areas are often necessary, we strongly recommend conducting a home inspection before construction begins.
