However, because of his intelligence, an evil and unknown organization tried to kill him with an unknown poison. Luckily, the drug did not kill him but turned him into a little kid.

First of all, the main character of this exciting series, Conan. His future as a detective was stolen as he was turned into a child. He has the brain of a professional detective and the body of a 7-year-old. ‘E’(江) means big river, ‘Do’(戸) is a door, ‘Gawa’川() means a river, and ‘Conan’(コナン) is written in Katakana because he took the name of his favorite author Conan Doyle which is in English.

Shinichi is Conan’s real name. As a teenager with a sharp brain, his detective life was just starting. However, as you know, his detective career would not continue for long. ‘Ku’(工) is a craft, ‘Do’(藤) is wisteria, ‘Shin’(新) means new and ‘Ichi’(一) is one.

Now let’s look into Shinichi’s close childhood friend, Ran. Kind and caring Ran deeply cares for her loved ones, one of them being Shinichi. She doesn’t know that Conan is Shinichi and has decided to wait for him to finish living his dream somewhere by believing that he will come back. ‘Mou’(毛) is hair, ‘Ri’(利) means profit, and ‘Ran’(蘭) is an orchid.

Love for Ukraine

Supporting Ukraine Kids together

As the situation in Ukraine escalates, I feel with emotions too overwhelming to name. There are many children in Ukraine whose homes have been destroyed and without food and water. Gentle support is needed.

Please donate to Save the Children.

According to Google Analytics, Japanese Names.info has been visited from 217 countries and regions for 30 days. Of course, Ukrainian and Russian users are also included.

For the kind Russian people

Apparently this isn't broadcast on Russian TV, but what the Russian government is doing isn't actually a peacekeeping operation, but is more correctly described as an invasion and looting of your relative's country, Ukraine.

The only power that can change the reality in Ukraine is for the Russian people to speak out. Please touch the world media outside of Russia to see how your government is causing the tragic situation. Thank you for a peaceful world!
