From 1927 to 1937, he worked in China for nearly eleven years, serving successively as the second-class secretary of the Japanese embassy in Beijing, the Japanese consul in Guangdong, and the first-class secretary of the Japanese embassy in Nanking (Consul-general of Nanking), etc. In 1939, he moved to Puppet Manchukuo and was promoted to Minister of Intelligence of Foreign Affairs Ministry. As a diplomat in China for many years, he found himself in the period when China was undergoing the Xinhai Revolution and the Qing dynasty was plunged into chaos and disintegration. As a result, the Qing government, princely families and high-ranking officials sold their famous paintings and calligraphy, antiques and precious artifacts in the market. Suma purchased a raft of renowned works including those from Luo Zhenyu, Duanfang, Wang Guowei, Qi Baishi, Pu Mo, Wu Hufan, Zhang Daqian, Liang Qichao, Cai yuanpei, Zhang Binglin, Wu Changshuo and Yu Jinhe.
