English, Chinese, and Japanese version Japan Real Estate Transaction Know-How Collection

We, SOZONEXT Co., Ltd. have developed a multi-language version of the “Knowledge DB System for Japanese Real Estate Transactions” in cooperation with expert in the fields of real estate trading, such as sales and purchase, brokerage, investment, auctions by court, and property management in Japan. Initially, the collection contains 3,000 items: 1,000 items in English, 1,000 items in Chinese, and 1,000 items in Japanese. We plan to add additional support for other languages as we add new and various real estate transaction knowledges.

Japanese real estate transactions, which are increasingly conducted internationally, are often perceived as “opaque,” “suspicious,” or “deceptive” both in Japan and abroad. In addition, there are few real estate companies and websites that can provide proactive support in multiple languages from pre-purchase/investment to asset management in order to ensure safe and secure real estate transactions in Japan from overseas.

We would like to contribute to the solution of the above problems by publishing, in multiple languages, answers to many of the questions that real estate professionals have actually been asked, as well as answers to items that the general public may have questions about, in as concise a manner as possible.

Achieving what is difficult for Internet search service provider websites

Most users of Internet search engine websites tend to refer to the information in the top search results, but that information is not always appropriate. There is a possibility that outdated articles based on old laws and regulations may appear in the top search results. In addition, it is not easy for Japanese people who are not familiar with real estate transactions to quickly obtain the answers they seek from a large number of websites. Furthermore, it is quite difficult for non-Japanese nationals who are not familiar with the Japanese language to obtain the necessary information in a timely manner.

Providing a lot of practical knowledges that are not readily available to the public

Portal sites for purchasing and investing in Japanese real estate provide glossaries of terms related to Japanese real estate mainly in Japanese. However, in order to purchase and invest in real estate safely and securely, it is not only important to know the meanings of the terms, but also to know how to deal with various problems that occur in actual situations. Such practical know-how is possessed by those who are busy with their daily work, but there are few companies that publish a lot of this valuable practical know-how in multiple languages.

In addition, there are very few companies that provide information in multiple languages other than Japanese on real estate transaction knowledge that differs greatly from other countries, such as real estate auctions conducted by Japanese courts, as well as knowledge on renting vacation home properties that are popular overseas. We published the various knowledges of vacation homes, such as 125 factors and examples that can negatively affect online reviews from users of vacation rentals.

Passing on safe and secure real estate transaction knowledge to the next generation

We will continue to contribute to the next generation’s safe and secure real estate transactions in Japan by creating and releasing a large number of digital data on Japanese real estate transaction knowledge that is hardly disclosed to the public.
