When renting a property, the Real Estate Brokerage Law (Takkengyoho) requires a Certified Real Estate Transaction Specialist (Takkenshi) to conduct an Important Matters Explanation. Traditionally, in-person implementation was mandatory, but after the 2017 Ministry of Land, Infrastructure, Transport and Tourism (MLIT) guideline revision (social experiment), the May 2021 amendment to the Real Estate Brokerage Law fully deregulated IT-based Important Matters Explanation (Important Matters Explanation utilizing IT).
Utilizing IT-based Important Matters Explanation is particularly convenient in the following scenarios.
IT-based Important Matters Explanation can be used in the following transactions.
However, regarding electronic signatures and document delivery of the Important Matters Explanation, this is linked with the provision of the Important Matters Explanation document through electromagnetic means under Article 35 of the Real Estate Brokerage Law (effective May 2022). Some real estate companies have cases where "IT-based explanation is available, but documents are sent by mail."
The requirements for IT-based Important Matters Explanation as defined by the Ministry of Land, Infrastructure, Transport and Tourism are as follows.
When applying for a property or after a viewing, inform the real estate company, "I would like an IT-based explanation." Not all real estate companies support IT-based explanations, so advance confirmation is necessary. Some small local real estate companies may not offer this service.
By the day before the IT-based explanation date, the Important Matters Explanation document will be sent. Whether it's delivered electronically (PDF) or by mail depends on the company. Be sure to review the content by the day before and make a list of questions. This is extremely important preparation to make effective use of the day's explanation.
Prepare the following equipment and environment.
If communication is unstable, the explanation may be interrupted, and in the worst case, in-person re-implementation at a later date may be necessary. It is recommended not to rely solely on smartphone mobile networks.
After the Certified Real Estate Transaction Specialist enters the video conference, the presentation of their license is presented first. The explanation then proceeds according to the Important Matters Explanation document. The time required is generally 30 to 60 minutes.
Ask questions actively. You have the right to ask questions just as you would in person. For parts you don't understand, feel free to say, "Please explain that again."
After the IT-based explanation, sign and stamp the rental agreement and Important Matters Explanation document (or use electronic signature). If documents are sent by mail, the typical process is to receive them first, sign them, and return them. With companies using electronic contract services (GMO Sign, DocuSign, etc.), the process can be completed entirely online.
The Important Matters Explanation document contains many items, but especially pay careful attention to the following points.
Matters Regarding Building and Equipment
Matters Regarding Contract Terms
Matters Regarding Costs
With the spread of IT-based explanations, searching for a room from a remote location and rental contracts for busy people have become significantly smoother. If you prepare with an understanding of the legal requirements and implementation flow, you can receive an explanation of the same quality as in-person.
When relocating or transferring from a distant location, or when a newcomer from abroad rents for the first time in Japan, choosing a real estate company that offers IT-based explanations can significantly reduce the burden of contract procedures. When contacting a real estate company, it is recommended to confirm first by asking, "Do you offer IT-based Important Matters Explanation?"
