Each design challenge is a unique opportunity for invention and expression, integration of artistic imperatives and pragmatic needs, and for the critical reexamination of cultural norms.


Riccardo Tossani Architecture (RTA) is an internationally renowned creative design studio that breaks down the distinctions between traditional disciplines. Our architecture is advanced through integration of all aspects of design, addressing master planning, building and landscape architecture, interior & furniture design. RTA’s capabilities ensure that all design and engineering components are tightly woven into an architecture that becomes part of the cultural landscape.

Based in Tokyo and licensed in Japan, RTA has award winning projects in Europe, the US, Asia and Australia.

With a strong presence in Niseko, RTA’s projects include the premier hotels and private residences in Hirafu and Hanazono, as well as master planning for the Hanazono and Grand Hirafu resorts.

Highly proficient European, American and Japanese trained architects and interior designers, licensed to practice on several continents ensure an architectural approach based on broad international experience.

Project capabilities include hotel/resort, all types of residential, corporate/office, interior design, programming and master planning. The studio also has considerable experience in product, furniture, graphic design and sculpture.
