No, Tokyo have great Soba, we don't need Udon or other.
I heard that a prefecture in Shikoku region chaged name to "Udon-ken" maybe last year?
Ah..., Sanuki? Kagawa? I never heard that prefecture's name.http://www.my-kagawa.jp/udon-ken/top.html
Now they are independent and issue own Udon-passport.http://www.my-kagawa.jp/event/passport/
Try to visit someday, If you have too much time to kill.
I think maybe they can't understand common Japanese...(lol
Ah, I remember I was born in Hiroshima.
They are good neighbors.(^_^;
And in Nagoya, they also have the original Udon called "KishiMen".
Ah, in Nagasaki there are "Chan-Pon" and some chain-restaurants named "RingerHut" are in Tokyo.http://www.ringerhut.jp/menu/chanpon/
And you know,
some popular ramen restaurants are always crowded in the underground shopping area of Tokyo station.http://www.tokyoeki-1bangai.co.jp/ramenstreet/
Or near Shin-Yokohama station.http://www.raumen.co.jp/ramen/
Or near Shinagawa station.http://www.shinatatsu.com/raumen/index.htmlhttp://park.tachikawaonline.jp/f-themepark/22_shinatatsu.htm
Of course, many many ramen restaurants are everywhere in Tokyo.
Even cheap ramen served in chain restaurants are tasty not so bad.http://hidakaya.hiday.co.jp/http://www.kagetsu.co.jp/
But I can't recommend ramen of "Osho", it's not joke. Other menu is good, but their ramens.http://www.ohsho.co.jp/
Sorry, such a long message...(x_x;
