This is the ranking of National Trends in Instant Noodle Demands. I could guess China would be No.1 and I thought Thailand or Indonesia would be No.2, and the rank of Japan would be high. BUT! I didn't suppose USA is No.4. Do you eat instant noodles often?? What is your best noodle? In Japan, there is a huge number of instant noodle types, cheap ones, expensive ones, soy sauce base soups, pork bone base soups, etc.
Maybe you know the Nissin Cup Noodle series, but the kinds of soup are so different from Japanese ones. You can check it on wikipedia. My favorite taste is Curry, I want to try the Crab taste of China, and the Tom Yam Goong of Thailand. I am not sure I want to eat the Broccoli of Germany and the Cheddar Cheese of Mexico.
And do you know the Maru-chan brand? I saw many Maruchan products in CA before. In Japan they are well known for their instant Japanese Soba and Udon series. But I can tell you ramen is much better than that, I recommend real Soba and Udon, not instant ones.
I think the most expensive instant noodle that you can buy anywhere will be Nissin Goota. It's about $3. The most reasonable one would be Nissin Chicken ramen or Nisshin Demae Iccho, they are about $1.
I heard Ippudo, famous for Kyushu type ramen (Pork bone base soup), is getting popular in NY now. Nissin collaborated on such popular ramen shops: Ippudo, Sumire (miso base soup), Santoka (salt base soup) and they had released a special ramen like this.
If you come to Tokyo, you may try this shop 'Akiba-noodle'. They have over 400 kinds of instant noodles and you can pick out, walk and eat what you want. Here is the inside of the shop.
