Frequently Asked Questions

Off-market properties are not listed on REINS (Real Estate Information Network System) and are not publicly available. High-value properties (hundreds of millions to tens of billions of yen) where sellers prefer "quiet transactions" are only circulated through trusted, limited channels. Through our proprietary sourcing network, we provide access to these rare property opportunities.

We deliver off-market premium property information weekly. Properties are shared as anonymous specs (overview information without specific location details). If you're interested, we'll provide full details after signing a Confidentiality Agreement (CA). Registration is free and can be canceled anytime.
