blue lid:KOJI launches a new series.
blue lid:KOJI delivers koji amazake and fermented seasonings from Minamiaiki Village, Nagano Prefecture.
This spring, "Koji Korokoro" and "Koji-ish," which propose new ways to enjoy fermentation, have joined our lineup.
### Flavors are Plain, Yuzu, and Chai (three types)
#### Koji Korokoro
A new type of amazake, made by freezing concentrated amazake into small, round shapes.
These cute, round, bite-sized amazake treats are delightful.
You can pop them into your mouth like ice cream.
Or put them in a glass and float them in soda or milk.
- 9 pieces, ¥702 each. Shop here.
- Also available in Matcha Hemp Protein, Seasonal Fruit (Cassis), and ROAST Brown Rice flavors.
#### Koji-ish
Koji amazake blended with oat milk, creating a mild and easy-to-drink texture.
Take it out of the freezer, and once it softens, gently knead the pouch a bit, then gulp it down as is.
It's a convenient amazake that can be enjoyed with one hand.
Perfect for after a bath or as a snack on a hot day.
- 130ml, ¥648 each. Shop here.
Until now, blue lid:KOJI has communicated the appeal of koji as an easy-to-enjoy "Natural Energy Drink" concept. With this occasion, we are restarting as a brand that creates space in daily life and mind through fermentation. Our slogan is "Let's ferment."
In today's world overflowing with convenience, how often do we take a deep breath or experience moments that make us smile? We believe that such "space" is essential amidst busy daily lives.
Fermentation is an activity that involves invisible changes accumulating over time, through interaction. We, as humans, also believe that our hearts are gradually filled by having "time to ferment."
To reward yourself for working hard, or to love yourself a little more. These feelings are encapsulated in the phrase "Let's ferment." This new product series is the embodiment of that sentiment.
Additionally, our official online store has been renewed so you can view these products more easily.
We also introduce ways to enjoy each product and seasonal recipes.
On our official Instagram, we regularly share updates on amazake making and scenes from Minamiaiki Village.

### Limited-time Mother's Day Gift
We are selling a special Mother's Day gift set for a limited time from April 20, 2026, to May 5, 2026.
This special set combines two types of amazake base with a wooden carnation that evokes the warmth of wood, and is presented as a gift to convey feelings to loved ones, themed "Forest Box for Expressing Gratitude."
The amazake bases are blue lid:KOJI's signature products: Shizu Tototoi (Plain) and Wa Hodoku (Yuzu), two types.
These are concentrated amazake types. You can enjoy them diluted in various ways according to your mood and physical condition.
The flower prepared for the Mother's Day gift is a wooden carnation from Kinohana kinano in Kitaaiki Village, Nagano Prefecture. It is an exquisite item that embodies the warmth of wood and the charm of craftsmanship.
Wood shavings from paulownia planings will be used as cushioning material. These were provided by a carpenter from Minamiaiki Village, and we decided to use them for this gift with the desire to effectively utilize forest by-products.
Please consider it as a gift for your cherished ones.
