Japotle doesn't exist, but Chipotle does. A chipotle or chilpotle, is a smoke-dried jalapeño which tends to be brown and shriveled. It is a chili used primarily in Mexican and Mexican-inspired cuisines, such as Mexican-American and Tex-Mex.
There are many varieties of jalapeños which vary in size and heat. In Mexico, the jalapeño is also known as the cuaresmeño and gordo. Until recently, chipotles were almost exclusively found in the markets of central and southern Mexico. As Mexican food became more popular abroad, especially in North and South America in the late 20th century and into the 21st century, jalapeño production and processing began to expand into northern Mexico to serve the southwestern United States, and eventually processing occurred in the United States and other places, such as China.
