My first batch worked so far, natto seems to be pretty good. I am keeping the starter in the freezer until I do my next batch.Here's how I made it in Instant Pot.1. Soaked the soybeans overnight.2. Cooked it in Instant Pot on Beans setting for 45 min. (Or High Pressure for 45 min).3. Strained the water out.4. While beans are still warm, added the starter and mixed. (I got too excited and added 3 scoops, but one scoop would have been sufficient).5. Set it on 'Yogurt' setting for 24 hours. Yogurt is 8 hours by default, so adjusted the time to 24 hours.I usually let the natto stay in the fridge overnight after making it. It can stay in the fridge for a few weeks.No issues with the starter, hopefully it will keep working since i'm keeping it in the freezer. It needs to be added to the beans while they are still hot to get activated. Adding it to the cold beans will not activate it. ### ⭐⭐⭐⭐⭐ Works *by T***A on Reviewed in the United States on 30 September 2024* I followed exactly as instructions say also I read some of reviewers that wrote their experience on here. I was able to make fresh and delicious and tasty homemade natto in the states. The product is very easy to follow, use. The natto smells very nice and stringy. It's definitely value for money. I am a very happy camper! ### ⭐⭐⭐⭐ Good product !! *by D***S on Reviewed in the United States on 11 November 2024* It does what its supposed to do. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/602551765-kawashimaya-natto-starter-spores-powder-100-made-from-organic-soybean](https://www.desertcart.hr/products/602551765-kawashimaya-natto-starter-spores-powder-100-made-from-organic-soybean) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-15*
