Hanamaru Udon Launches New “Rich Shrimp Tsukejiru Udon” and Classic “Rich Seafood Tonkotsu Tsukejiru Udon” for a Limited Time

Key Takeaways: Hanamaru Udon is running two dipping-broth udon nationwide from September 10 to late October 2026. The new Rich Shrimp Tsukejiru Udon builds its broth from shrimp ground shell and all plus shrimp-infused oil, at 840 yen for a small. The returning Rich Seafood Tonkotsu version, with its pork bone depth turned up this year, starts at 790 yen.

Silky Sanuki Udon Meets Bold Dipping Broth This Autumn

Hanamaru Co., Ltd. (headquartered in Takamatsu, Kagawa Prefecture; President: Yoshihiro Maeda), operator of the Sanuki udon chain Hanamaru Udon, will begin selling two limited-time menu items — Rich Shrimp Tsukejiru Udon and Rich Seafood Tonkotsu Tsukejiru Udon — at Hanamaru Udon locations nationwide (excluding some stores) starting Thursday, September 10, 2026. Hanamaru is part of the Yoshinoya Holdings group.

Both dipping broths were developed to pair perfectly with udon. Despite their bold, concentrated flavors, the supple, silky texture unique to Sanuki udon keeps every bite going down smoothly to the very last mouthful. Chilled, firm noodles dipped into piping-hot broth make for a seasonal treat worth seeking out.

New: Rich Shrimp Tsukejiru Udon — Shrimp Flavor, Fully Concentrated

This year’s newcomer is the Rich Shrimp Tsukejiru Udon, which fills the mouth with shrimp umami and aroma. The broth combines shrimp ground into powder shell and all with an oil infused with shrimp extract, producing a dipping sauce that is both fragrant and deeply savory.

The topping features shrimp, steamed chicken, and white scallion tossed together and coated in the umami-rich shrimp oil, delivering an intense aroma alongside a variety of textures. It pairs beautifully with both the broth and the Sanuki udon, leaving a lingering shrimp finish with every bite.

Classic: Rich Seafood Tonkotsu Tsukejiru Udon — Now with Stronger Pork Bone Depth

The perennial favorite is the Rich Seafood Tonkotsu Tsukejiru Udon, a punchy special broth where seafood umami meets the deep richness of pork bone. This year the tonkotsu umami has been intensified, making the bowl richer than ever before.

Finish Every Last Drop with Wari Soup (Kakedashi)

All tsukejiru udon items come with Hanamaru’s signature wari soup (kakedashi) for diluting the broth. This original kakedashi combines ichiban dashi — extracted for maximum umami from carefully selected iriko (dried sardines) and kombu — with a kaeshi blended from several premium soy sauces and salt.

Pour it into the concentrated dipping broth after finishing your noodles, and the refined aroma of iriko and its profound umami bloom, turning the remainder into a superb Japanese-style soup you can enjoy down to the last drop. For those craving heat, a spicy fish powder topping (50 yen, tax included) is also available, letting you dial in your preferred spice level.
