リスナー情報コーナー(木) おなかGOO！GOOD！グルメハンター：すき屋「Sukiシェイク 焼き芋」
Sukiya's (すき家) limited-time "Suki Shake Yakiimo" landed on the radar of the Thursday gourmet segment of Jane Su: Seikatsu wa Odoru (ジェーン・スー 生活は踊る), after a listener spotted it at the beef-bowl chain. Hosts Sū-san and corner regular Ugajin Megu (ウガジン・メグ) tasted an S-size cup live in the studio and praised both the flavor and the surprisingly low price. The shake blends a vanilla base with beni haruka sweet potato sauce and crushed imo-kenpi (芋けんぴ) chips for a distinctly autumnal result.

What this episode answers
What kind of product is Sukiya's "Suki Shake Yakiimo"?
It is an autumn-limited shake available at the beef-bowl chain Sukiya, made with a vanilla shake base, beni haruka sweet potato sauce, and crushed imo-kenpi as a topping.
What sizes and prices does it come in?
It comes in three sizes — S for ¥210, M for ¥260, and L for ¥350 — and Sū-san praised the L at ¥350 as exceptional value.
How did the hosts describe the taste after drinking it in the studio?
Both hosts' first reaction was "Delicious!"; they described the imo-kenpi as a satisfying crunchy accent and praised the balance as not too heavy or sweet, with Sū-san likening the potato presence to "sweet potato sitting a couple of seats diagonally in front of you, not right next to you."
When did Sukiya's shake series launch, and what flavors have been offered so far?
The Suki Shake series launched in 2023 and has featured limited-time flavors including vanilla and matcha; baked sweet potato is the autumn 2026 addition.
What operational question did the hosts raise about the shakes?
Sū-san wondered how Sukiya, with its enormous number of stores, produces shakes without rolling out dedicated shake machines to every location, and called on listeners with part-time work experience at Sukiya to explain the actual preparation process.
Hyogo Listener Tips Off the Show to a Hidden Gem at Sukiya
A Thursday edition of the "Onaka GOO! GOOD! Gourmet Hunter" (おなかGOO！GOOD！グルメハンター) segment brought an email from a listener named Heso Penguin (ヘソペンギン), writing in from Hyogo Prefecture. Heso Penguin noted that autumn is the season when every restaurant chain rolls out sweet-potato sweets, but that this year's sleeper hit turned up somewhere unexpected: Sukiya, the beef-bowl chain. The listener had simply gone in for a regular gyudon and happened to spot the shake on the menu. Corner host Ugajin Megu brought an S-size cup into the studio so that she and Sū-san could taste it on air.
Product Details: Vanilla × Beni Haruka × Imo-Kenpi
The Suki Shake Yakiimo is built on a vanilla shake base, layered with a sauce made from beni haruka sweet potato, and finished with crushed imo-kenpi on top. Three sizes are available: S at ¥210, M at ¥260, and L at ¥350. Sū-san was immediately delighted by the S size — "This is exactly right! Frappuccinos should make a size like this too" — and just as taken by the value at the top end: "¥350 even for the L is remarkable."
Sukiya's shake lineup has been running since 2023, rotating through limited-time flavors such as vanilla and matcha. Baked sweet potato is the face of the range for autumn 2026.
Studio Tasting: "Sweet Potato Sitting a Couple of Seats Diagonally in Front of You"
The first words out of both hosts after their first sip were simply "Delicious!" They agreed that the pairing of vanilla shake and sweet potato paste is straightforwardly correct — the kind of combination that needs no defense. The imo-kenpi topping added a light, crunchy texture that both found to be a welcome contrast to the smooth base.
Sū-san reached for a memorable spatial metaphor when describing the intensity of the sweet-potato flavor: "It's not like sweet potato has sat down right next to you. It's more like sweet potato is in the seat a couple of places diagonally in front." In other words, the potato presence is real and satisfying, but it never becomes heavy or cloying — a balance both hosts called spot-on.
The ease of drinking turned out to be almost a problem. Sū-san admitted she had to physically remove the straw from her mouth to stop herself from finishing the cup in one go, adding that she had placed the cup far away from herself for that reason. Ugajin agreed: "If I didn't pay attention, I'd just vacuum the whole thing up in one go." That was despite both hosts already having eaten quite a lot that day, which made the shake's pull all the more impressive.
Sū-san also mentioned that social-media posts comparing this autumn's sweet-potato drinks from various chains frequently name the Suki Shake Yakiimo as the best of the season. She confessed she had been curious about it for a while and declared it "even better than I imagined."
"I Can't Sleep for Wondering" — The Shake Operations Mystery
After the tasting, Sū-san raised a question that had evidently been simmering in the back of her mind. Sukiya operates an enormous number of stores across Japan, making it unrealistic, she reasoned, to have installed dedicated shake machines in every single location. If that is the case, how exactly are the shakes being made — presumably with whatever standard kitchen equipment the stores already have? "Won't someone look into this? I can't sleep for wondering," she said, and put out a direct call to any listeners who have worked part-time at Sukiya to write in and explain how the production actually works.
Takeaways
- Sukiya's Suki Shake Yakiimo — vanilla base, beni haruka sweet potato sauce, and crushed imo-kenpi topping — starts at ¥210 for an S size and drew unqualified praise from both studio hosts.
- The shake's strength is its balance: the potato flavor is present and distinct without being heavy or overly sweet, and the imo-kenpi provides satisfying crunch, with social media also singling it out as the top sweet-potato drink of autumn 2026.
- Sukiya's shake series has been running since 2023, but how the chain produces shakes across its vast store network without dedicated machines remains an open question that Sū-san is calling on former part-time staff to answer.
