While Makoto Shinkai’s latest film, “Weathering With You,” has already been released in Japan, it’s likely anime fans overseas won’t be able to see the movie until 2020. However, there are a few moments in the film that may leave international audiences scratching their heads when they finally get to see it.

Ghost-like figures with strings tied around their necks can be seen throughout the movie, from rain-soaked hospital windows to umbrellas adorned with the smiling dolls. Even the Twitter emoji for #WeatheringWithYou is one of the white objects. But what the heck are these things?

They’re teru teru bōzu charms, which serve a special purpose in Japanese culture. They are believed to help stop the rain and guarantee that tomorrow will be sunny.
