This article explores the symbolism of blue in Japanese culture and how it is used in art and design. Blue is often seen as a sign of peace and tranquility, trustworthiness, honesty, and loyalty. It is also thought to bring about feelings of calmness and relaxation. When it comes to business attire in Japan, blue is generally seen as an appropriate color choice for both men and women alike. Bright colors like red or yellow should be avoided when doing business due to their association with passion/anger (red) or joy/energy (yellow) respectively while black should be avoided unless attending a funeral ceremony due its association with mourning within traditional Japanese culture.
