Pairon Main Store

Pairon, also rendered Hōryū or Hakuryū, is closely associated with Morioka jajamen. At the Uchimaru main shop, flat noodles arrive topped with meat miso, cucumber and seasonings. Diners mix them to taste with garlic, ginger, vinegar or chilli oil. At the end, you can leave a little noodle and ask for chi-tan-tan: egg goes into the bowl and staff add hot noodle water to make a light soup.

The official website identifies this location as the main shop and lists its address and phone number, but not a dependable daily schedule. Call before travelling to Uchimaru, especially if you have a connection to catch or plan to arrive near closing. It is in the central district near Morioka Castle Site Park and municipal offices, so it fits a historic walk.

Reviews describe the table-side seasoning ritual and egg finish as part of the experience; more critical comments mention a milder flavour than expected, soft noodles or long queues. Jajamen invites diners to taste, adjust and mix. If you do not like heat, begin with little chilli; if the flavour feels mild, add condiments gradually. Pairon and Pyonpyonsya show two of Morioka’s three signature noodle styles.
