Product FAQs

What are the best before dates?
Each product comes with its own label and expiration date. The expiration is written in Japanese: 賞味期限 (shou-mi-ki-gen) and the format is yyyy/mm/dd. 

See product details below for individual product information.

Do your products come individually packed?
Yes, most of our products come in portion sizes and are individually vacuum packed. Please check below on the product page for more details.

How does temperature-controlled delivery work?
Products remain at their appropriate temperature from our door to yours. If you purchase items requiring different temperature ranges (i.e. frozen and dry), they are automatically divided into two separate shipments based on their needs. For more details on delivery methods and shipping fees, please check this page.

Where do I leave a review?
Thank you very much for your support. Every product page has a 'Leave a Review' section at the very bottom. Please feel free to leave an honest review. All reviews are anonymous and don't require an account. Once submitted your review will show up immediately and be public for everyone to see. Please do not include personal information.

Are your products Halal or Kosher certified?
We do not specifically carry or import halal or kosher products. Some items are labeled as kosher or halal by default from the country of origin.

Until what temperature can I sous vide the meat in its own packaging?
Our packaging is sous-vide ready (the process of cooking meat in its packaging in hot water for a prolonged time) for water temperatures up to 95°C (200°F). We do not recommend temperatures close to the boiling point but temperatures around 60°C (140°F) with a cooking period between 45 minutes and 3 hours, depending on the type and thickness of the meat.

These premium organic brown mushrooms from the Netherlands are sliced thick (7mm) for a satisfying texture and full-bodied flavor. Each 500g (1.1lbs) pack includes a mix of small and large slices—some even twice the size of the mushrooms you might find in typical Japanese supermarkets. Nothing goes to waste: all edible parts are carefully used.

Certified organic under Japan’s JAS standards, these mushrooms are grown without pesticides or chemical fertilizers. They’re harvested at peak freshness, quickly washed and sliced, then flash-frozen to lock in their just-picked taste and nutrients. Mushrooms are naturally low in calories and rich in potassium, zinc, vitamin D, and B vitamins—making them a delicious way to add nutritional value to your meals.

The bold, earthy aroma and deep, savory flavor of this brown mushroom variety shine in every bite. Their meaty texture holds up beautifully in gratins, pastas, and oil-based dishes like ajillo. They also release a rich umami broth when cooked, making them a fantastic addition to soups, stews, steak sauces, or a quick sauté with your favorite protein. They’re an incredibly versatile ingredient that enhances almost any dish.

Also perfect as a pizza topping! The pizza shown in the second product image was made using these mushrooms, our organic pizza base, and our organic grass-fed cheddar cheese.

About Certified Organic

This product is certified organic in both the EU and Japan according to strict standards. But what does certified organic mean when it comes to fruits and vegetables?

✔ Strictly tested for E Coli, coliforms, molds, yeasts as well as listeria and salmonella and therefore meets very high microbiological safety standards.

✔ Free of harmful synthetic chemical inputs such as fertilizer, pesticides or any food additives.

✔ Free of genetically modified seeds (non-GMO)

✔ The farmland and soil in use are free of any chemical treatments.

✔ Organic produce is heavily regulated. Producers and importers are checked and inspected by governmental bodies or certified third parties. Organic certification requires detailed bookkeeping and documentation for 100% traceability. "Certified organic" is a protected phrase and the use is legally restricted.

✔ Organic farming is more sustainable when it comes to holistic food production. The lack of harmful pesticides is better for the environment.

✔ Organic produce comes mostly from family-owned farms that own smaller acres of organic land.

It is also important to mention that organic produce is more cost-intensive. Organic farming has lower yields compared to conventional farming and is oftentimes more labor-intensive as well. Additionally, organic certification and audits require annual fees for producers, exporters, and importers resulting in higher prices for the end consumers.

Please note that non-GMO and chemical-free produce will often have a minor degree of defects; these may include individual differences like slight deformities, discoloration, and under/over ripeness. In rare cases there may be insect damage, scratches, or mold which cannot be seen during inspections. However, these are not harmful and can simply be removed. Thank you for your understanding.
