April 2026 reporting described a Japanese-language forum gambit hawking roughly 2.4 million lines (~2.78 GB in some posts) tying together consumer real-estate brands including SUUMO, CHINTAI, At Home, HOME'S, Ouchino, and Chintai EX.
Analysts cautioned that the corpus could stem from consolidated scrapes rather than a single defender perimeter; BreachHistory therefore tracks the saga as marketplace-sourced pending operator corroboration.
Canonical record: Japanese real-estate portals 2026 forum bundle on BreachHistory.
