In this period Chiang also was active in the assembly petition campaign. In 1926 when the crown prince of Japan visited Taiwan on an inspection tour on his father ’ s behalf, the governor-general launched an island-wide welcoming campaign. Arches were erected, flags were put up, and at night lanterns were lit. The Taiwan Daily News, the main Japanese-language newspaper of that time, published fawning poems and articles.
此時蔣渭水仍積極參與議會請願運動，一九二三年日本裕仁皇太子代父出巡台灣，當時的台灣總督發動全島「奉迎」，除搭牌樓外，並命民眾白天執歡迎旗，晚上提燈放煙火，「台灣日日新報」刊登頌讚詩賦，大獻殷勤。
