Hanamaru Udon’s “Founding Anniversary Hanamaru Fest” Starts November 20
Hanamaru Co., Ltd. (headquartered in Takamatsu, Kagawa), a Yoshinoya Holdings group company that operates the Sanuki udon chain Hanamaru Udon, will hold its “Founding Anniversary Hanamaru Fest” at stores nationwide from Friday, November 20, 2026, as a thank-you to its customers. The fest features two special offers—a free Chikuwa Isobe-age, the signature tempura that has sold more than 100 million pieces in total, and a “¥100 off any udon” coupon—plus a giveaway campaign on the brand’s official X account.

Hanamaru Udon opened its first store in Takamatsu, Kagawa in May 2000 and founded Hanamaru Co., Ltd. in November 2001.

The fest marks the company entering its 26th year in November 2026 and expresses gratitude to its longtime customers.
