Rômazi Aiueo

What is this site?

Rômazi Aiueo is the website for the purpose of understanding and dissemination of romanized Japanese (romaji). It is an effort that let Japanese people learn the basics of romaji and use it more widely.

Romaji is a basic knowledge of the Japanese language taught at elementary school. However, few Japanese can write romaji correctly. Many foreigners have noticed that the spelling of romaji written by the Japanese is not consistent. The reason for this is that Japanese people do not understand how to write romaji correctly and often write them incorrectly. You may be surprised to learn that the Japanese government and companies, for political or economic reasons, deliberately ignore the official rules and use writing styles that are not only academically incorrect but also undesirable in international relations. Even more troubling, many of the explanations of romaji found on the Internet are of poor quality, and these spread misunderstandings.

In the age of the Internet, the fact that Japanese people cannot write Japanese correctly has become known throughout the world, making foreigners wonder why. This is internationally embarrassing. This situation should be changed. That is the primary purpose of this site, which is basically designed for Japanese people. However, there are many people in Japan who want to imitate foreigners, and if foreigners learn and use the correct romaji, Japanese may start to imitate them. Therefore, we hope that foreigners will learn the correct romaji and spread it around the world.
