I heard about 600 new instant ramen/a year are launched in Japan and just two or three ramen noodles get the honorable name as "standard".
For prospect students or expats from other countries...
Even if you just stay here for a year or two, your ramen diary must be a great ramen anthropological study. But I highly recomend that more balanced diet would lead to your longer ramen noodle diary in your eighty or ninety.
