Part of a Complete Breakfast

What is this stuff?

It’s koji granola from SAN-J.

But… like… what is that?

According to an article on the efficiently named FoodBev Media celebrating the product’s release in 2025:

SAN-J, a well-known name in the Asian condiment sector for its authentic Tamari soy sauce, has launched Premium Koji Granola, marking the brand’s first venture into the snack category.

So that covers the company. They do, among other things, Tamari soy sauce. Which is perfect, because who would you trust with a sweet, crunchy breakfast item more than the makers of the world’s most savory condiment?

Sorry, sorry. We shouldn’t undercut it yet. After all, we’ve only identified the brand’s speciality, but we’ve barely said anything about the product.

From that same article:

Crafted with rice koji, a fermented ingredient recognised for its digestive benefits, the granola is sweetened with rice koji syrup, which provides a naturally delicate sweetness akin to maple syrup.

Okay, we’ll be honest, we’re a bit more intrigued now. The only problem is, we don’t exactly know what koji is.

Luckily, we found a quick rundown on the on the less efficiently named Yummmm! Bar:

At its core, rice koji is steamed rice that has been inoculated with a specific mold called Aspergillus oryzae, also known as the “koji mold” or “koji starter.” This traditional Japanese fermentation method has been used for centuries in the making of miso, soy sauce, and sake. During the fermentation process, the mold breaks down starches in the rice into simpler sugars, creating a naturally sweet and digestible food base.

Hey, there you go. It’s all coming together. Maybe it isn’t crazy for a soy sauce maker to get into the granola game.

The article goes on to say that koji has no added sugars, and also expands on the claims made above about how it promotes healthy digestion:

But the benefits of rice koji go far beyond taste. The fermentation process unlocks a range of bioactive compounds, including probiotics, amino acids, enzymes, and B vitamins. These nutrients not only support digestion but also help create a balanced intestinal environment. Interestingly, even the dead bacteria from fermentation continue to play a role in gut health, offering support to your microbiome.

Sounds almost too good to be true. And maybe it is. But who cares if the granola tastes good, right?

Which, by the way, we can neither confirm nor deny at press time, due to the fact that there are zero Amazon reviews of this stuff.

But it sounds good to us.

And if you’ve had it (or even if you’ve tried a product like it), definitely let us know what you think in the comments.
