In Japan, the 7th of July is known as Tanabata (the 7th night). Some parts of the region, like Sendai, celebrate Tanabata in August.
Tanabata is a summer celebration that involves beautiful paper-folding (origami), eating delicious snow cones (kakigoori), and wish-making on tanzaku (strips of paper) that hang from bamboo branches.
This holiday is also celebrated in China, where it’s known as Qixi.
