Also known as: きのこたけのこ戦争
Kinoko vs Takenoko (lit. 'Kinoko-Takenoko War') is a debate between consumers over which one of Kinoko No Yama and Takenoko No Sato (branded as Chocorooms and Chococones respectively in the United States), both made by Meiji (Brand), is better.
Backstories were developed, and people spread "violent" images of war between the two pieces of Candy, with the question of which of the two Chocolates a Japanese person prefers being joked as a "forbidden question". This trend of comparing the two products began in the 1980s and became an Internet Meme in the 21st century.
