SIWA is a product brand that uses "Naoron," developed by the long-established Japanese paper manufacturer, Oonachi. It is characterized by its soft texture, flexibility, water resistance, and high durability. To commemorate the exhibition of collaborative works between Oonachi's Japanese paper and Yuya Hashizume at this exhibition, a self-customization workshop will be held for customers who purchase SIWA products in stores during the exhibition period.
This is a special event that will only be held during this period. Please join us!
