Query: Buyer beware!

I'm a Japanese national, and as far as Japanese names are concerned, most of the author's picks in this book are seldom correct. And when they are correct, they are obscure. I saw a lot of crazy ones that cannot be names, and the meanings are often nonsensical. This makes me sucpicious about the credibility of other names from other cultures.
