When attending a Japanese wedding, it is important to be aware of the cultural nuances that come with the event. Colors such as black, white and red should be avoided due to their associations with negative meanings within their culture. Traditional attire such as kimono or yukata are often expected for guests and muted shades such as pastels or earth tones are usually best. Other items of clothing that should not be worn include shorts, tank tops, sleeveless shirts, flip flops, hats/sunglasses/jeans/t-shirts/sweatpants/athletic shoes/baseball caps etc.. Gift-giving etiquette should also be followed when attending a Japanese wedding - cash gifts are usually preferred over physical gifts and should never exceed ¥50 000 unless specifically requested by the couple.
