overview

Mirocco, a new indoor playground that opened in Kakegawa City, Shizuoka Prefecture in July 2025, aims to be a place where not only children can play to their heart's content, but also families and local residents can enjoy together.

This facility was built by renovating the swimming pool and hot spring facilities at Tamarina, an indoor facility in 22nd Century Hill Park in Mansui, Kakegawa City, and renovating it into an all-weather playground. Utilizing our know-how in regional revitalization and facility management, we were responsible for the entire project, from concept formulation to design, construction of interiors, play equipment, decoration, and operation.

Furthermore, as an independent DBO* project, Mitsui has implemented private investment in this facility, enhancing its appeal through the addition of play equipment, built-in furniture, signs and graphics, etc.

Facility concept/spatial concept design
The concept of the facility is "Let's create an inspiring everyday life." The name "mirocco" was decided by vote, with the intention of creating a facility that everyone will want to visit 365 (3=mi/6=ro/5=ko) days a year and where everyone can gather.
 

The four main areas are "Guru Guru no Yama" where you can play with play equipment, "Waku Waku Base" where you can play quietly, "Hitoyasumi Lounge" where adults can relax, and "Haihai no Hara" where babies can play safely. In addition to these areas, "This Is Cafe", which has new stores in Shizuoka Prefecture, has opened in Tamarina and offers menus that are easy for customers of all ages to enjoy.

In addition, the facility's interiors, play equipment, benches, and other interior features use local resources, with environmentally friendly materials used throughout, such as benches made from timber harvested from local forests, a work space where scraps and waste materials are used as craft materials, and plaster walls made from soil from Kakegawa.
 

*DBO: Design Build Operate, a business model used to develop public facilities. The public sector commissions private businesses to design, build, and operate the facility.
