A home inspector is a qualified professional who assesses and reports on the current condition of a building’s foundation, subfloor, attic, interior, and exterior.

These characteristics are influenced by the relationship between the house design and the natural environment. When renovating, it is crucial not to neglect these characteristics.
Ignoring them can lead to defective houses that are not durable in rain or resistant to earthquakes. Unfortunately, there are currently many defective houses.
Below are some characteristics of buildings and natural phenomena:
- ① Long eaves
- ② High attics
- ③ Wooden construction
- ④ High underfloor
- ⑤ Japanese roof tiles
- ⑥ Use of plantations
- ① High temperature and high humidity
- ② Earthquakes
- ③ Rainy season
- ④ Typhoons
- ⑤ Mold
- ⑥ Termites
- ⑦ Ticks
Our country has unique characteristics compared to other countries.
Our inspector, equipped with five core skills, applies exceptional expertise to assess properties from various angles. Going beyond surface-level checks, the inspection thoroughly evaluates both the interior and exterior for durability and seismic resilience.
We prioritize your best interests, offering detailed reports, renovation advice, and tailored solutions. Additionally, we conduct defective home investigations, identifying the causes of defects and preparing expert reports for legal cases when needed.
I, Kosei Watanabe, who practiced as a carpenter in my youth, have experience building tea ceremony rooms and traditional houses. After gaining independence from my carpentry training, I worked on small houses.
Ten years later, at the age of 31, I established my company, Kei Watabe Co., Ltd., and now run Kei Watanabe Architect Office. We have worked with lawyers to investigate defective housing. Our strict perspective as a carpenter and architect allows us to conduct thorough inspections. Additionally, we can offer optimal renovation suggestions.
We use techniques from Switzerland and traditional Japanese construction methods to ensure your house is in good condition for you and your family.

New Construction Process Confirmation Inspection
Residential construction involves more than 15 different specialists working on tasks such as ground surveys, foundation work, and carpentry. Without specialized knowledge, it can be difficult to evaluate the quality of these processes. By having a skilled inspector confirm each stage of construction, you can ensure both the safety and quality of your new home. Our inspections also encourage construction companies to maintain high standards, as people tend to avoid cutting corners when they know they are being watched.
Our Super Home Inspector will also consult workers about their tasks in your presence when necessary, ensuring your peace of mind throughout the home-building process.
