The research paper of our gardeners Tomio Sakaue, Sanae Handa and company president Tomoki Kato was recently published in the 'Technial Reports of Landscape Architecture No.9, 2017' by the Japanese Institue of Landscape Architecture. The paper explains the implementation of diligent care of wildflowers as an essential value in Japanese garden management. It is known that Aritomo Yamagata, the founder of the garden, enjoyed the naturally blooming wildflowers.
