Since 2014, Yokohama has partnered with KaBOOM! to provide children with play opportunities that will ensure they grow up to become healthy and productive adults. In 2015, Yokohama built its first playground with KaBOOM! followed by a second one in 2016. Yokohama looks forward to building its third in 2017.
