Shimonita Konnyaku Farm Table is a farm-to-table dining experience on a working konjac farm in Shimonita, Kanra District, Gunma — a village at the western edge of the prefecture recognised as one of the highest-quality konnyaku-producing areas in Japan. While Gunma as a whole produces approximately 90% of Japan's konnyaku supply, Shimonita's combination of volcanic highland soils, significant diurnal temperature variation, and clean mountain water yields corms with a distinctive firmness and minimal bitterness. The Farm Table experience combines a guided farm element — a short walk through the growing fields where the taro-like konjac corms are cultivated — with a prepared lunch that places konnyaku at the centre of every dish. Farm konnyaku sashimi is the opening course: freshly processed konnyaku blocks, sliced and served raw with two dipping sauces (a sesame miso and a ponzu citrus) within hours of being made from the day's harvest, offering a freshness impossible with commercially distributed product. Shimonita negi and konnyaku nabe is the main hot pot course: Shimonita's second celebrated agricultural product — a thick, sweet variety of Japanese leek grown in the same volcanic soils — combined with white and black konnyaku blocks in a light dashi broth seasoned with soy. Miso konnyaku dengaku skewers, baked on the farm's outdoor grill, recreate the traditional street-food preparation of konjac chunks glazed with sweet miso and cooked until the glaze caramelises. The experience operates on a reservation-only basis and accommodates groups of two to fifteen. Weekday service is suspended from November through March when the farm is less active outside the growing season; weekend availability continues year-round.

Frequently asked questions
Is the farm walk included in the price?

Is konnyaku suitable for people with food allergies?
Konnyaku itself contains no common allergens; however, the accompanying dashi broth and miso sauces contain soy and fish-derived ingredients. Communicate all dietary requirements when booking.
