Japan gradually increased its exposure to Western culture since the Meiji Restoration . It is observable that the trend became more rapid especially after the Second World War. Without exception, the influence on the culinary was one of them. When reflecting on the Japanese cuisine of today, we could see that it first took in large portion of foreign components and then evolved to the next level – meaning the “new concept”. For instance, in the school caterings for the kids, curry rice is the most popular; from online voting result, ramen ranked the most attention-grabbing. Simply many foreign-origin foods which have captured the taste bud of Japanese.

In reality, despite the popularity of curry rice or ramen, the local normally do not have them daily. However, there is a dressing commonly found on the dining table, some make it a “must-have” in every meal by dipping it on every single thing they eat. Could you imagine that it is Mayonnaise?

What is “Mayoler”?

Let’s get into the details. Some Japanese simply crazy about mayonnaise. They not only have it on salad or okonomiyaki, but also on bread and rice – beyond imagination. The start of introduction of the term “Mayoler” in Japan, referred to mayonnaise fans, was unknown.

Although, “Mayoler” is only specific to Japan, let’s not forget the fans who cannot miss mayonnaise in their daily meals can also be found throughout the world. There are foreign fans who only look for Japanese made mayonnaise and will bring many home each time they visit Japan.

Kewpie Mayonnaise – Top selling brand in Japan

When we think of these mayonnaise fans from different parts of the world, we should not ignore the efforts of “Kewpie Mayonnaise” for building up this fame.

Kewpie is the first enterprise in Japan who manufactured mayonnaise. The company was established at Nakano, Tokyo in 1919 and started its first production six years later in 1925. Today, it even has productions in USA, China and Thailand. This helps to strengthen its reputation in North America and Asia. For foreigners who are craving for “Kewpie”, “Kewpie” is always there to serve.

What is it so unique about Kewpie Mayonnaise? With your inquisitive mind, it is time to be on-site to find out the truth.

Kewpie has nine production sites across Japan of which five are open to the public (free admission) – Goka Plant (Ibaraki Prefecture), Fuji Yoshida Plant (Yamanashi Prefecture), Koromo Plant (Aichi Prefecture), Kobe Plant (Hyogo Prefecture) and Tosu Plant (Saga Prefecture).

A reminder to foreign visitors on some challenges of the visit – three key areas are:
