Last year, the rumored quiet sale of a 5.5 billion Yen (approx. 50 million USD) apartment in central Tokyo broke price records. Although the sale has not been confirmed, if true, this would make it the most expensive apartment to have ever been sold in Japan, exceeding the previous record of 4.4 billion Yen paid for a penthouse apartment in Domus Minamiazabu during the bubble era in the late 1980s / early 1990s.
The 580 sqm (6,241 sq ft) apartment is one of two apartments occupying the top floor of the 7-story Park Mansion Hinokicho-Koen. The building was developed by Mitsui Fudosan Residential and construction was completed at the end of April 2017.
