Shin-Tsunashima MICCA, a commercial complex centred on a traditional Japanese house with approximately 170 years of history, opens today. The traditional house and newly built wooden commercial facilities have been developed as an integrated complex, creating a pedestrian-oriented space connecting the station frontage with the surrounding streetscape.
The complex consists of 3 buildings: OMOYA, a traditional Japanese house originally built in 1860, and 2 newly built wooden commercial facilities, HANARE Minami and HANARE Kita. Renovation of the traditional house was completed on 30 September 2026, the new buildings were completed on 1 October, and the complex opened on 28 October. TOKYU CORPORATION was responsible for planning and promoting the overall project, Sumitomo Forestry for design and construction, and Rebuilding Architecture Research Institute for the master plan and design supervision.
The design is based on the principle of “not creating edges in the city.” Low-rise wooden commercial facilities were placed between the high-rises in front of the station and the traditional house, with an emphasis on a figure-eight circulation route linking the traditional house, garden, plaza and wooden facilities. The earthen-floor and veranda spaces of OMOYA were preserved and renewed, while seismic resistance and building systems were upgraded. HANARE is a two-storey structure made entirely of wood, with veranda-like spaces that connect the interior and exterior through extensive use of timber.
Based on an assessment using ONE CLICK LCA, CO2 emissions were reduced by approximately 34% compared with a steel-framed building of similar scale. Approximately 829 cubic metres of timber were used across the complex, sequestering approximately 703.31 tonnes of carbon. Coatings with enhanced weather resistance were applied to the exterior timber, and the front facade was designed to expose the wooden columns. In addition, the weeping cherry tree “Taiko Chiyo Shidare®” was donated to help improve the local landscape.
Through the preservation and utilisation of historic assets, the complex aims to create a place where people can experience history and culture in everyday life. It also aims to contribute to regional revitalisation as a new hub for interaction linking Tsunashima's history and vitality.
