Normally, Sado reminds Wabi Sabi (acceptance of transience and imperfection) but Shogun Hideyoshi Toyotomi made a Tea room which has totally opposite concept “Golden Tea Room”.
Based on the document, the Golden tea room is disassembly / assembly room which were covered by gold everywhere such as wall, roof, pillar, slides, tatami mat, etc.
Almost all Japanese says it is bad taste but I guess Hideyoshi was enjoying who looked and amazed his special tea room. As he is known as mischievous.
