A Fair Playing Field for Real-Estate Investment.

Japan's real-estate market is one of the largest and most liquid in the world — yet information asymmetry still defines it. The fairness of a price, the right level of rent, the future of a neighbourhood: information that should be equally accessible to everyone has long lived with a small group of insiders.

I founded TLL LLC to change that structure.

TLL is a group of practitioners that handles the full lifecycle in-house — acquisition and resale, rental management, and private-lodging / hotel operations. At the same time, we are a technology company: we design and run Urbalytics, a real-estate data-analytics platform built by operators for operators. The reason TLL exists is this fusion — practitioners who know the field, turning data and AI into their own tools.

Our goal is a world where newcomers and cross-border investors in Japan can decide with the same information and the same precision as long-time industry veterans. Regardless of nationality, entity type, or company size — everyone should be able to make decisions grounded in evidence. That is the fair playing field we keep building, on two engines: operations and technology.

Over the next ten years, the shape of the real-estate industry will change dramatically. We do not intend to receive that change passively — we intend to design it with our own hands. TLL is a rapidly growing company, and in that conviction we are confident we are second to none.

We will continue to engage honestly with the field, with the data, and above all with our clients.
