ELI5: Explain Like I'm 5

Fujizuka

A fujizuka is like a little mountain made by people in Japan to honor a famous mountain called Mount Fuji. People would bring rocks, dirt, and plants to build the fujizuka, and then they would climb up to the top to pray and show respect to the real Mount Fuji. It's like making a special cake for your best friend's birthday and putting candles on it to show how much you care about them. Even though the fujizuka is not the real Mount Fuji, it is still important to the people who made it and to the community.
