The 2.9-MW solar park Otaki Village was built on a former ski area.

Juwi Shizen Energy, the joint venture founded in 2013 between the German project developer juwi and the Japanese developer of wind and solar parks Shizen Energy, has successfully completed the construction of an free-field solar park in the Japanese province of Nagano, where the 1998 Winter Olympics took place. This project also benefits from the fact that juwi Shizen Energy is a specialist in the construction of utility-scale solar PV-parks on challenging terrain as the three-hectare solar park is located on a former ski slope. 

The Japan joint venture has recently successfully implemented several projects of this type. The company is currently building a 121 megawatt solar park on the site of a former golf course in Sanda City in Hyogo Prefecture, which is located in the Kansai region north-west of Osaka on the island of Honshū. The annual yield will be around 143 million kilowatt hours. The solar park is scheduled to go into operation in December 2023. It is the largest single project in the history of the Japanese joint venture to date.
