Why Is Choco Monaka Jumbo
Always Crispy—No Matter Where You Buy It?

The biggest enemy of a crisp “pari-pari” texture is moisture.
Ice cream contains a large amount of water (about 60%), and over time, this moisture gradually transfers to the monaka wafer.
As the temperature rises, this moisture transfer happens even faster—and for monaka, even as little as one gram of water can be a serious problem.

To slow down moisture absorption, Morinaga has developed a special chocolate coating spray system that applies an ultra-thin, even layer of chocolate across every surface. In addition, Morinaga’s research labs and factories work closely together to continuously refine each component—the monaka wafer, the ice cream, and the chocolate—to ensure the crispy texture that everyone loves!

Even before the product reaches convenience stores and supermarkets, strict quality control is maintained.

While it is common practice to place large orders to boost sales, Choco Monaka Jumbo follows a different approach. We ask our retail partners to cooperate with detailed inventory management practices that are not typically required for ice cream products—such as ordering only what has been sold and strictly adhering to a first-in, first-out system, where items are sold in the order they arrive.

Thanks to these efforts, we are able to consistently deliver the same great taste to customers across Japan.

To deliver Choco Monaka Jumbo to customers in its perfectly crispy state, we aim to have the product on store shelves within five days of production, placing strong emphasis on demand forecasting.

If sales exceed expectations, our intentionally limited inventory can quickly lead to out-of-stock situations. On the other hand, if sales fall below forecasts, excess inventory may result in reduced freshness.

To improve the accuracy of this critical demand forecasting process, Morinaga began a collaboration with the Japan Weather Association in 2017. By using AI to analyze weather data alongside historical shipment data, we are able to generate more precise demand forecasts.

From manufacturing to distribution and retail, every step is carefully designed to preserve that signature crunch—so no matter where you buy it, you can always enjoy that unmistakable sound and texture.
