Mr. Ishii makes of premium konnyaku and shirataki products, which come from the root of the konjac plant (Amorphophallus konjac). The secret behind their incredible health profile is glucomannan, a powerful dietary fibre found abundantly within the tuber. This unique fibre has an extraordinary ability to absorb water, expanding gently in the digestive tract to promote a long-lasting feeling of fullness and satiety. Rooted in a rich history of traditional Japanese food culture, these staples offer an excellent halal, gluten-free, vegan and high-fiber substitute for traditional rice and noodles. Because of this high glucomannan content, they naturally aid in digestion, help lower cholesterol and slow down sugar absorption to manage blood sugar spikes, making them perfect for low-carb and keto diets. Within the product range, konnyaku grain is the dried grain form, while shirataki is the noodle form of the product.

The pristine production journey begins when the konjac tuber is harvested, thoroughly cleaned, peeled, and sliced. The slices are then dried and ground into a fine flour before being shaped into grains and noodles. Finally, they are dried once more and packed in a strictly sterile environment to ensure safety, hygine and longer shelf life. Combining ancient food tradition with modern safety, Mr. Ishii products carry official Halal and Vegan certifications, alongside international JAS (Japanese Agricultural Standard) and ISO quality benchmarks.
