1. Embrace The Slurp
Not like how most of us were taught about table manners, it is completely acceptable to slurp your noodles in Japan, with incredibly logical reasoning.
Firstly, the Japanese believe that slurping will enhance the taste of the noodles by stimulating your appetite. Your slurping is also a mark of respect to the cooks who dedicated their time to making your noodles, signifying that you're enjoying what you're eating.
Secondly, because ramen is often served piping hot, slurping allows you to cool your noodles and make it easier to swallow.
While it may seem odd at first to slurp your noodles, you'll find it extremely liberating and practical once you start to do so. Just as this writer has joyfully experienced.
