Ummm... I find it distasteful to tell you what your homepage is, but,
to me, <http://www.kanzaki.com/> does not look like your homepage.
Rather, it looks like a page that you've created. I say this because
<http://www.kanzaki.com/> (at least the English version) does not
contain any information about you, but rather it contains information
about Arts & Books, Japan, and Metadata & the Sematic Web. In other
words, I would say

[a foaf:Person;
foaf:name "Masahide Kanzaki";
foaf:homepage <http://www.kanzaki.com/> ] .

is not true, but

[a foaf:Person;
foaf:name "Masahide Kanzaki";
foaf:made <http://www.kanzaki.com/> ] .


Hope this helps,
