Kominka – Japan’s Traditional Homes
Kominka Projects
In recent years, kominka have been attracting increasing attention both in Japan and overseas.
In the past, the most common uses were kominka cafés, restaurants, and relatively low-priced kominka accommodation facilities. Recently, however, there has been growing demand for large-scale renovations that transform kominka into luxury villas or high-end accommodation facilities.
Demand for the purchase, restoration, and use of kominka is expected to continue increasing in the future.
Those reading this page are likely interested, at least to some extent, in kominka and kominka projects. However, there are several points that should be kept in mind when considering a kominka project.
Before moving forward with a property search, it is also important to understand the preparation required for real estate projects in Japan.

Kominka Are Not a Standardized Market
Kominka attract many people, but kominka projects involve practical hurdles that cannot be overcome by dreams or admiration alone.
Even Japanese buyers sometimes abandon projects or encounter major problems after purchase. In many cases, this happens because of insufficient preliminary research, inadequate strategic planning, or unrealistic budgets with little room for flexibility.
Kominka represent a market that is both old and new.
In Japan’s real estate market, where land value is extremely dominant, kominka are unusual in that the value of the building itself is also highly significant.
There is no clear benchmark market price for kominka.
This is because rarity, the unique characteristics of each property, differences in condition and scale, and varying value assessments by different brokers coexist in the market.
Kominka with excellent condition, scale, and location do not appear on the market in large numbers, and repairs or renovations after purchase often require time. As a result, patience is necessary throughout the project, and flexibility in location, conditions, and budget may also be required.
In addition, various applications and permits are often required for utilization.
In Japan, besides national laws, municipalities and management associations often have their own rules, so there are many matters that must be confirmed before searching for or purchasing a property. For example, the existence of a nearby ryokan does not necessarily mean that the same type of business is permitted.
In Japanese real estate projects, research and confirmation must be conducted for each individual property rather than simply relying on nearby examples. This is particularly important because kominka were built before the current versions of the City Planning Act and the Building Standards Act came into force.
Thinking About Budget
In kominka projects, it is impossible to calculate the total budget for purchase and renovation accurately in advance, even though these two elements account for most of the cost.
However, in practice there are rough guidelines for the minimum budget.
Approximate minimum budget guidelines:
Purchase of a large kominka and luxury renovation: from about 150 million yen
Purchase of a large kominka and basic repairs: from about 80 million yen
Purchase of a small to mid-size kominka and repairs: from about 40 million yen
These are only approximate lower-end guidelines. The actual amount varies depending on the property and the scope of renovation, but they can serve as a useful reference.
First, regarding property prices. Although the market does not have a standard benchmark, larger kominka with high-quality buildings, large floor areas and land size, and multiple kura storehouses on the property tend to be in higher price ranges and also show a wider range of prices.
In the higher price range above 100 million yen, properties often have favorable conditions such as access to tourist areas, proper road access, well-developed infrastructure, or good building condition. In addition, highly rare properties such as samurai residences have high inherent value in the buildings themselves. Because these properties often have large land areas, prices can exceed 50 million yen even when large-scale repairs are expected.
Large kominka also tend to have high basic repair costs simply because of the building size and the number of rooms. Maintenance and operating costs should also be considered when planning their use.
These large kominka with high rarity and quality often have structures that can accommodate luxury specifications, allowing a wide variety of renovation possibilities depending on the owner’s ideas. Luxury renovations exceeding 100 million yen are not uncommon.
On the other hand, kominka priced below 10 million yen often require particularly careful investigation. Such properties frequently have issues such as poor building condition, poor road access, or limited transportation access, and may also include farmland.
Low-priced kominka often lack essential infrastructure such as a municipal water connection or a septic system, or they may require major roof repairs. Confirming these conditions in advance is important for financial planning. If large-scale repairs are entrusted to a construction company, it is safer to assume repair costs of around 30 million yen.
In recent years, DIY renovation of kominka has become popular, but there are parts that can be handled personally and parts that should be entrusted to professional specialists.
Kominka are fundamentally different structures from typical Japanese wooden houses or two-by-buildings, from the materials used to the construction methods themselves. How repairs and renovations are carried out can significantly affect the lifespan and safety of the building.
For this reason, it is strongly recommended to carefully consider renovation plans in advance and establish a realistic repair plan and budget.
Kominka Are a Field Where Japanese Standards Remain Strong
The kominka market, related businesses, and the communities surrounding them are areas where traditional Japanese cultural practices remain particularly strong.
One reason is that medium-sized and large companies, especially major corporations, rarely enter the kominka market. From a business perspective, the market is difficult to scale, highly specialized, and securing skilled carpenters is challenging.
Because of these strong barriers to entry, many of the hard elements adopted by larger companies, such as compliance frameworks, contracts, and operational systems, are less commonly introduced in this field, from real estate transactions to construction.
Japanese business culture generally emphasizes close local relationships and trust-based networks. This tendency is especially strong in the real estate industry, and it becomes even more pronounced because many kominka are located in rural areas rather than major cities.
It is a world where the assumptions of global business do not necessarily apply. It is a world governed by what I describe as the Japanese OS, where traditional trust relationships and personal networks remain central, and where communication is conducted in a high-context, distinctly Japanese manner.
In particular, the business styles and professional values of carpenters and builders who work with kominka are strongly influenced by craftsmanship and pride. Rather than directly applying overseas business customs or assumptions, it is necessary to approach them in ways that are acceptable to them.
For Those Considering a Kominka Project
Kominka attract many people because of their unique character, historical and cultural value, and compatibility with modern needs.
At the same time, restoring and utilizing a kominka requires realistic strategies and budgets grounded in practical considerations. For overseas buyers in particular, responding to the Japanese OS, which can sometimes appear irrational, is an issue that should be seriously considered.
Overcoming these challenges is not easy, but it can also be highly rewarding.
When construction is completed and the property finally begins its new life in use, the sense of satisfaction can be profound.
Please prepare carefully and take on the challenge of a kominka project. I hope this article will serve as a useful reference.
