In Japan, red is traditionally seen as a symbol of joy, happiness and celebration. It is also associated with strength and power, and is often used to decorate homes during festivals or special occasions such as weddings. However, there are some superstitions surrounding the color red that suggest it may be unlucky in certain contexts. Wearing red clothing when visiting a shrine or temple is considered bad luck, as is wearing it on one's wedding day. There are also beliefs that too much 'red energy' inside one's home can attract negative spirits. Despite this, red still has positive associations with weddings in Japan - brides often add a splash of color with a bright obi belt made of silk or velvet fabric dyed scarlet-red!
