Hello friends, have you noticed? The Japanese penny selling shop sells black ink pens rather than blue ink pens. Because of the use of black ink pen in Japan to fill important documents. If you find a hurry. May be black ink is replaced.

Why do Japan need black ink pens?

Because the seal of Japan is red. Make a clear cut with black. And if the documents are copied. It is clearer than black. If it is not important, it will use a blue ink pen. But if we write letters with red ink pen. Some people in Japan believe that. Will not meet again anymore.

If you have the opportunity to apply for a Japanese company. Then use a black ink pen to fill out the application. You may be attracted by the management. More than using a blue pen. I do not know how to do it.
