According to the Garden History Society, Japanese landscape gardener Seyemon Kusumoto was involved in the development of around 200 gardens in the UK. In 1937 he exhibited a rock garden at the Chelsea Flower Show, and worked on the Burngreave Estate at Bognor Regis, and also on a Japanese garden at Cottered in Hertfordshire. The lush courtyards at Du Cane Court – an art deco block of flats in Balham, London, built between 1935 and 1938 – were designed by Kusumoto. All four courtyards there may have originally contained ponds. Only one survives, and this is stocked with koi. There are also several stone lanterns, which are meant to symbolise the illumination of one's path through life; similarly, the paths through the gardens are not straight. Japanese maple, Japanese anemone, cherry trees, evergreens, and bamboo are other typical features of Du Cane Court's gardens.
