Grand Mercure Minamiboso Resort & Spa Collaborates with Kimura Peanuts for One-Day-Only Autumn Lunch Event Featuring Peanuts and Local Ingredients

Located within the Minamiboso Quasi-National Park at Taibusa Misaki, a scenic cape surrounded by rich nature and overlooking the Pacific Ocean, the resort hotel "Grand Mercure Minamiboso Resort & Spa" (Minamiboso City, Chiba Prefecture; General Manager: Shintaro Fukuda) will collaborate with "Kimura Peanuts," a specialty peanut shop established in 1968 in Tateyama City, Chiba, to host a one-day-only lunch event on October 4, 2026 (Sunday), celebrating the seasonal flavors of Minamiboso.

This event marks the third installment in a series of seasonal lunch events showcasing the unique culinary charm of Minamiboso.

For this special occasion, the hotel's chef has crafted an exquisite French full-course menu using Kimura Peanuts' homegrown peanuts from their Farm in the Boso region, alongside other local autumn ingredients such as Chiba-grown Ise lobster, Minamiboso-caught swordfish, and returning bonito. Additionally, each participant will receive a special gift box from Kimura Peanuts containing boiled peanuts, hand-shelled peanuts, domestic "mizore" peanuts, domestic butter peanuts, and seasoned domestic peanuts—allowing guests to continue enjoying the flavors of the event at home. Furthermore, every Sunday in October, Kimura Peanuts will host a peanut and sweet potato harvesting experience at their farm, offering families a hands-on opportunity to connect with the autumn bounty of Minamiboso.

- Bonito Cutlet with Roasted Peanut and Bacon Dressing

Rich, fatty returning bonito is prepared as a cutlet and served with a dressing of roasted peanuts and bacon. The nutty fragrance of peanuts and savory depth of bacon enhance the bold flavor of the bonito.

The dressing uses naturally brewed soy sauce from Miya Shoyu in Futtsu, Chiba—a traditionally fermented soy sauce made without artificial temperature control, adding depth and umami.

Tenderly steamed Minamiboso swordfish is paired with the refreshing sweetness of Shine Muscat grapes and the salinity of caviar. A white wine sauce infused with peanut flavor adds a smooth, rich depth to the delicate fish.

Wagyu ribeye is gently slow-cooked to achieve a tender, juicy texture and bring out its natural umami. Served with a savory pilaf of Chiba-grown Koshihikari rice and mushrooms, enhanced with truffle aroma—a deeply satisfying dish embodying the essence of autumn.

### Dessert

A Mont Blanc featuring peanuts and sweet potatoes—two iconic autumn ingredients. The smooth, creamy texture and gentle sweetness provide a perfect finish to the course. The ice cream, made with milk from "Minoaka Kobo," the birthplace of Japanese dairy farming, uses fresh raw milk from Minamiboso City, offering a rich, authentic dairy flavor with a clean finish.
