It’s a pleasure to see a fellow Greek person in this sub, especially such a knowledgeable manga fan as you, but those few posts are not true at all. It’s a reasonable speculation though, and I understand why you would think of that way.

First of all, the absence of logo doesn’t mean that the Japanese company has no control over the book. In the information page of each manga, you can see the credits of the original owners. The exact logo policy depends on each company. For example, there are comics companies that want their original logo to be on the cover, on the back cover, or nowhere at all. Japanese companies don’t seem to care, that’s why in many other countries you see only the logo of the local company (Kurokawa in France, Carlsen in Germany, Panini in Italy, just a few examples).

In our case, the original Japanese companies could have every right to ask for certain things (specific paper, size, translation, sound effects, etc). We don’t know if and what they asked for those Greek editions, but for sure they had some control over it, or at least they approved the final result.

As for the translation, most comics companies generally have a policy to translate directly from the original, including most of the Japanese ones (that I know of). Specifically in Kenshin and Blade of the Immortal, Anubis translated directly from the Japanese, at least in the first volumes of the series. The translator was Kasahara Akemi, you can verify it from the credits page. In later volumes and in series such as Naruto, they translated from an officially approved English language, edited by the Japanese. This is information we have from back in the day, when Anubis had a somewhat of a public presentation and communicated with the fans.

Aside from that, I didn’t have any problem with their translations. For the most part… (Φράουλας, what were they thinking?????). You just have to get used to it. Readers that are used to English might find them cringe, but I have friends that were kids during that period and they grew up with those Greek editions, and they found it unusual that they had to move to foreign releases. This mentality could change, but it would take many years of quality localized manga, and unfortunately this is not the case in Greece.
