Top 5 Lactose-Free Milks Available in Japan

Does your stomach feel uneasy after drinking milk? You're not alone. Many people experience bloating or discomfort after having dairy, and in many cases, lactose intolerance is to blame. Lactose is the natural sugar found in milk, and if your body doesn’t produce enough of the enzyme needed to break it down, it can lead to digestive issues. In fact, it’s quite common in Japan, where many people have lower levels of this enzyme without even being aware of it.

That’s where lactose-free milk comes in. These specially formulated products are gentler on your digestive system and are gaining popularity across Japan. In this article, we’ve rounded up five of the most-purchased lactose-free milk products on Amazon Japan from the past month. Whether you’re looking for something suitable for infants, a health-conscious adult, or anyone in between, these picks are worth considering.

If you’re wondering what exactly is lactose-free milk or which one to try first, don’t worry. We’ve made it easy to understand and choose the one that best fits your lifestyle.
