I have a book on Japanese folklore, and I'm hoping to translate popular and well-known ones here.
Here's a short tale.
Mr. Carrot, Mr. Gobou, and Mr. Daikon
Mr. Carrot, Mr. Gobou and Mr. Daikon were preparing a bath.
Fluffy puffs of steam appeared and the bath was ready.
"I'll be first."
Mr. Carrot jumped in. It was very, very hot and he couldn't handle it. Even so Mr. Carrot tried his best and counted the numbers.
"One, two, three, four, five, six, seven... It's no use!!"
Mr. Carrot turned red and jumped out.
Mr. Gobou watched and slowly entered the bath. "Hot!" he cried and jumped out. He ran away still covered in dirt.
"Add water in it if it's hot."
Mr. Daikon poured water into the steaming water and went in the bath. He slowly submerged himself in the bath and cleaned himself carefully.
"Ah, that felt nice."
After getting out of the bath, Mr. Daikon's body became white.
This is why a carrots is red, gobou is dirty and daikon is white.
