I Tried Nissin Big Cup Noodle Mystery Meat Festival

Have you ever heard of Mystery Meat in Nissin Cup Noodles?

The reason why the meat cube in the Nissin’s top-selling instant ramen is called Mystery Meat is that Nissin hadn’t announced the detailed ingredients contained in the cube until 2017.

Since the first flavor of the Cup Noodle series was introduced into Japan’s market in 1971, the identity of the meat cube had been a mystery for 46 years.

Actually, according to the official announcement Nissin made in 2017, the mystery meat cube is a freeze-dry food consisting of minced pork and vegetables.

Since 2016, Nissin has offered this Cup Noodle Big “Nazo Niku Matsuri (謎肉祭 : Mystery Meat Festival)” once a year for a limited time.

This year, the product was released on September 16, so I purchased this for this blog article.

When you peel back the paper lid about halfway, you see a lot of mystery meat cubes in the cup.

I checked how many meat cubes are included in the cup. As you can see in the photo, there were about 40 pieces of mystery meat in the container.

Once these freeze-dried meat cubes are rehydrated, they have a distinctive tender texture and add umami to the soup.

Cooking Instructions 

How to make this instant ramen is the same as usual: Pour boiling water into the cup, up to the inside line.

Close the lid and let the noodles sit and cook for 3 minutes.

3 minutes later, remove the paper lid and you can enjoy the festival food.


The broth has a pepper soy sauce flavor and is a little spicy. The soup base is the same as that of Nissin Cup Noodle Soy Sauce flavor (Amazon.com).

The noodles are thin and soft as usual, while the mystery meat cubes have juicy umami and a pleasant tender texture, making this instant ramen a very satisfying noodle dish.
