The Tokyo Ramen Show ended today after 5 glorious days. From what I can tell from Google Translate, there are 27 different booths featuring a wide variety of shops and chefs. Booth "SP1" features "Hall forbidden bizarre collaboration Nakahon × Tanmen Mongolia", which is described as "Miso black pork". It certainly sounds interesting, although I don't know what "black pork" is. Probably it's just a bit of mistranslated text. This link shows the list of vendors. If you use Google Chrome, the Google Translate is integrated once you load the site.
