This is a set of five Otsu-e paintings created on wood eaten by shipworms from Lake Biwa. The set includes five paintings, from "Fuji Musume" to "Raikou no Taiko Tsuri" (Thunder God's Drum Fishing). The backs of the paintings retain the shipworm-eaten marks, which have now weathered. These are Otsu-e paintings drawn on old wood eaten by shipworms from Lake Biwa. Originally, both sides were likely in the same shipworm-eaten condition, and it would have been possible to finish the back as beautifully as the front. However, the artist intentionally left it as is, likely to emphasize that it is shipworm-eaten wood. This shipworm-eaten wood is sometimes used as a floorboard in tea rooms for displaying flowers. It is also rare because it cannot be artificially created. For reference, searching "funamushi-kui-ita" (shipworm-eaten wood) will yield descriptions such as "boards with unique textures and patterns (worm-eaten patterns) created by the marks (damage) left by marine organisms called 'funamushi' (shipworms) on the bottom boards of ships or old wood." This shipworm-eaten wood is quite large, and such pieces are now nearly nonexistent. The size is approximately 128 cm wide, 36 cm high, and 2.5 cm thick. - Design: Traditional Japanese patterns - Material: Wood - Style: Art panel - Colors: Multicolor (red, green, black, white) - Decoration: Hand-painted characters Thank you for viewing.
