This garment is a jinbaori, a weatherproof surcoat that developed in Japn in the 16th century to be worn over armour. By the time this example was made, in the 18th century, Japan was at peace and jinbaori no longer had to withstand the rigours of battle. Instead they were worn purely for ceremony and were designed to emphasise the power and status of the samurai. The design of jinbaori reflected the individual tastes of the warriors who wore them and they were often made of unusual or expensive materials. It was certainly a samurai of flamboyant personality who wore this jinbaori which is decorated with peacock feathers.
