Mitsui Fudosan, one of Japan's leading real estate companies, has implemented a new policy aimed at curbing the resale of its 'Tower Mansion' properties. The new approach involves confiscation of the earnest money if a property is resold within a specified period. The move is seen as a step towards stabilizing the real estate market and preventing speculative buying.

In Japan, the soaring prices and high demand for tower mansions, specifically in tightly regulated markets such as Tokyo, have given rise to cases of speculative buying. This has led real estate companies like Mitsui Fudosan to take initiatives to maintain a stable housing environment. The society values fairness in the real estate market, hence such measures are seen as significant.

In the US or EU, practices to discourage or penalize quickly flipping properties also exist, although they vary by location. They may include significant taxes on profits from resales within a certain time frame, or required disclosures about the intent to resell. Mitsui's approach of earnest money confiscation is relatively unique.
