Ice cream is undeniably one of the most popular items sold onboard the Shinkansen trains. It's a tempting treat that many passengers find hard to resist. However, have you ever noticed that the ice cream you buy onboard can sometimes be quite hard? Let's delve into the reasons behind this phenomenon and uncover the secret of "Sujahta High-Quality Ice Cream," known as "Shinkansen Sugoi Katai Ice," a favorite among Shinkansen passengers.

The Science Behind the Firmness

It's easy to wonder if the ice cream is frozen rock-solid to prevent it from melting as it travels around the train. While that might contribute to its hardness, there's more to it than meets the eye. This particular ice cream has a higher butterfat content (15.5% in vanilla) compared to regular ice cream.
Moreover, it contains significantly less air, resulting in a denser consistency. These factors combine to give the ice cream its firm texture.

The Trade-Off for Creaminess

The higher butterfat content and reduced air result in a trade-off. Yes, the ice cream is firmer, but it's also exceptionally creamy and smooth on the palate. This unique manufacturing process ensures that passengers can savor a rich and velvety ice cream experience that's different from the typical light and airy treats.

Perfect Timing for Enjoyment

While the firmness might not be everyone's preference, there's good news for those who enjoy a smoother scoop. If you purchase the ice cream and let it sit for about 10 minutes, you'll find it's at the perfect consistency for indulgence. So, next time you're on the Shinkansen and craving some Sujahta High-Quality Ice Cream, exercise a little patience for a truly delightful treat.


The mystery of why the Shinkansen ice cream is so firm is rooted in its high butterfat content and low air inclusion. This unique approach results in a dense yet creamy treat that provides passengers with a distinct ice cream experience. So, the next time you're onboard, give this delectable treat a try and savor the balance between texture and flavor.


For those fortunate enough to ride the Tokaido Shinkansen before October, why not seize the opportunity to experience the "Shinkansen Sugoi Katai Ice" through onboard sales?
(Note that this ice cream will continue to be available for onboard sales on certain sections and trains of the Tohoku Shinkansen and Sanyo Shinkansen after November 2023)
