A pair of English teachers at a language school in Kagawa Prefecture are promoting sanuki udon noodle bowls, a dish popular in the region, to foreign visitors through a poster explaining the intricacies of dining at local eateries.

More than 200 of the posters, titled "An English Guide to Sanuki Udon" and made by American Jeremy Lanig and his British coworker, Gary Wilkinson, have been distributed to udon restaurants in Kagawa.

The idea for the poster came from Lanig, a 37-year-old udon enthusiast. When he came to Japan in 2006, he faced what he considered a complex system of ordering at udon restaurants.
