Every spring in Japan, cherry blossoms bloom, giving the country a pink hue. This is why pink is seen as a spring color. It's also why this McDonald's hamburger has pink buns.
In the past, McDonald's has released special sakura, or "cherry blossom," teriyaki egg burgers that are slathered in a special sakura sauce (a pink mayo with Japanese radish spread). These are limited time only meals for spring.
