Clash of Clans started Japanese support. It's very natural

Supercell started Japanese support in Clash of Clans.

 Though it was written as "クラッシュ・オブ・クラン" under the title, did you notice? This wrote Clash of Clans in Japanese katakana.

 Characters speak Japanese lines.

All the item names and explanation are transcribed in Japanese, too.

There are very good and natural. And the fonts harmonize with a design. Usually, Japanese support of overseas games are very strange and funny. Or they become unnatural because they were translated exactly. They are sentences such as the example sentence of the textbooks. However, the Japanese support of Clash of Clans is natural. They seem to understand even the Japanese style spoken language and internet and game slang. They studied Japanese? or employ the Japanese staff?

By the way, GungHo announced the details of the collaboration with them in Puzzle & Dragons.

These are screenshot under development.

In this collaboration, characters of Clash of Clans appear in the dungeon of Puzzle & Dragons. Their designs are arranged to harmonize with an atmosphere of Puzzle & Dragons. Probably artists of GungHo would draw them. The collaboration begins on June 24.
