Making noodles from scratch? That is very difficult or do you mean recipes using Japanese noodles?

You just boil it like spaghetti (2c to a 1/2" diameter bundle for 3 minutes) and flavour to your liking. For some other ideas, you can look here: Japanese recipes - Japanese noodle recipes - Japanese food .

This looks wonderful
 

this looks so delicious it is little bit different than the Chinese recipe but i like it.
