For those confused: Japanese ramen is thought to be originally China's reimen. Most nutritional anthropologists (food historians) agree that, around late 19th Century (and recent as post-WW2), those who lived, worked, and/or fought in China moved back and started a noodle shop, based on the reimen they had in China, and this is now commonly known as what most people now know as ramen. Instant noodle ramen was also made by a Japanese man named Momofuku Ando, around post-WW2, who was also Chinese-Japanese (Chinese-born Japanese; to be specific, what is now known as Taiwan).

for bit more specifics on why translator and author/mangaka emphasized "ra" part, they're pronounced same. Thing is, however, Chinese and Japanese are romanized differently...
