Raw Materials Essential to Intangible Cultural Heritage –Starting the Survey on Common Reed (Phragmites Australis) in the Riverbed from Udono to Kanmaki in Osaka
Raw materials of reeds (mouthpieces) of hichiriki (a Japanese flute), is common read (Phragmites Australis; Genus:Phragmites, Family:Poaceae). Especially common reeds growing on the land near the rivers and the lakes are said to be suitable for hichiriki’s reeds. Udono and Kanmaki areas of the Yodo River riverbeds in Takatsuki City, Osaka Prefecture, are well known as a production area of the good quality common reeds grown in the land. For long time, Udono Association for Common Reed Riverbeds Preservation and Kanmaki Working Union have been working to slash common reads and burn the reed riverbeds there to preserve reed riverbeds and exterminate harmful weeds and insects during every February. However, due to the unsuitable weather condition and the COVID-19 pandemic, this work could not be carried out for two consecutive years. We were concerned about the common reeds growing environment. From September 2021, the information was spread that the common reeds in that area were almost extinct.
The Department of Intangible Cultural Heritage has been engaged in the surveys on conservation techniques to transmit traditional performing arts, and the tools and raw materials for these arts. The common reeds are mandatory as raw materials to support gagaku (a Japanese classical music, which are mainly played in courts and shrines.) Therefore, we documented and studied reed riverbeds burning held on Feb 13th, 2022, first time in two years.
They plan to improve the environment for common reeds growing under the initiative of Udono Association for Common Reeds Riverbed Conservation and Kanmaki Working Union by stripping vines which coil around and blight reeds. The department continues to closely monitor the activities as an important attempt to secure the raw materials, which are mandatory for the conservation for cultural properties.
