Earth Inc. is a Japanese housing platform company founded in 2024 and headquartered in Minato, Tokyo. Its business is not a single SaaS product; instead, it spans the standardized housing concept βGarden Wall House,β the housing history management platform βEarth ID,β the License Partner program, and project management that combines architecture, IT, and real estate. From an enterprise software perspective, Earth ID is the closest thing to a SaaS/platform product.
According to the official website, Earth ID is positioned as a housing lifecycle platform. It aims to centrally manage design, construction, renovation, and transaction histories, helping visualize the asset value of homes and improve transparency in the pre-owned housing market. The product is still under development and is expected to launch in June 2026. Garden Wall House, meanwhile, is a standardized housing solution for residences, villas, hotels, and similar use cases. It emphasizes a design philosophy centered on walls and gardens, balancing privacy with a sense of openness. The partner program allows companies to adopt the base model on a per-building basis under their own standard specifications and brand names.
The official website does not disclose any plans, pricing, trials, or payment methods. It also does not specify whether Earth ID will be deployed as a public cloud, private deployment, or hybrid solution. There is no public information on third-party integrations, APIs, developer documentation, permission systems, team collaboration features, or data security and compliance. As a result, at this stage it is difficult to evaluate its purchasability and IT implementation costs against mature SaaS standards.
Its strengths lie in a clear positioning: it targets long-standing issues in Japanβs housing market, such as fragmented property histories and the difficulty of transparently assessing asset value, while combining architectural design, real estate, and IT. If Earth ID is delivered as planned, it could offer practical value for housing transactions, maintenance, and asset management. The drawbacks are that the product has not yet been released, and the website lacks customer cases, interface previews, data security details, service support information, and business model specifics. Its software maturity and verifiability are therefore limited.
It is most relevant for Japan-based housing developers, architectural design/supervision firms, real estate companies, and partners interested in standardized housing collaboration. Chinese companies involved in Japanese real estate or cross-border residential asset management may want to keep an eye on it. However, if the need is domestic construction management, real estate SaaS, or BIM/property asset management in China, Mingyuan Cloud, Glodon, and local engineering project management systems may be easier to implement. There is no clear evidence regarding access to the official website from China, and payment methods have not been disclosed.
