This is one of the gardens displayed in the Hokkaido Garden in Kamikawa Town. We do not have any "Gardening Competition" in Hokkaido but we have Garden Trails at the center part of Hokkaido.
I heard that a Japanese gardener got the straight third championship in the Garden Competition in the United Kingdom.
We Japanese people live in this small islands admiring other creatures, paying consideration to the circumstances that nurture the tangible and intangible lives on the globe. That might be the base of the gardener who was praised by the Majesty Queen Elizabeth.
