Bonkei (盆景) is a Japanese art form that creates miniature landscapes using dry materials such as rocks, sand, clay, and cement. Unlike bonsai, which uses living trees, bonkei does not contain any living material. Bonkei can be temporary or permanent, and can depict various scenes such as mountains, islands, villages, or farms. Bonkei is displayed on a tray and may include miniature figures and models to enhance the realism. Bonkei is different from bonseki, which is a flat sand-painting that is usually erased after viewing. Bonkei aims to provide a pleasing and detailed representation of nature for display and contemplation.
