Video Recording of Noriutsugi Harvesting and Inspecting the Dissemination Activities in Shibetsu Town
“Neri,” a substance extracted from noriutsugi trees, is essential for making Uda washi (Japanese traditional paper) that is used for cultural property restoration. Under the strong sunshine in early summer, people in Shibetsu Town, Hokkaido, carefully remove bark from noriutsugi and peel off its outer parts by hand to extract the inner parts. Furthermore, to reduce reliance on the wild species, they have begun to grow noriutsugi trees in nurseries.
Four members of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN), Mr. NISHIDA Noriyoshi, Head of Analytical Science Section, Center for Conservation Science, Ms. ICHIMIYA Yae, Associate Fellow of the same Center, Ms. MAEHARA Megumi, Head of Intangible Cultural Properties Section, the Department of Intangible Cultural Heritage, and Mr. ODAWARA Naoya, Associate Fellow of the same Department, visited Shibetsu Town from June 24 to 27, 2025. They inspected the process of barking noriutsugi and peeling off its outer parts, and video-recorded the way to grow nursery trees with talks provided by the related parties. They also participated in and video recorded dissemination activities, including a workshop by Mr. FUKUNISHI Masayuki, a holder of selected conservation techniques for handmade washi essential for mounting (Uda washi paper) held at the Shibetsu Town Culture Hall, targeting elementary school students and the wider public. These videos are planned for use in research, education, and dissemination related to the succession of cultural properties after editing.
TOBUNKEN concluded an agreement on collaboration and cooperation on materials for cultural property restoration with Shibetsu Town on November 2, 2023. Recording and disseminating the activities to ensure sustainable supplies of noriutsugi and dissemination activities are expected to benefit this collaboration and cooperation.
