Japanese uses four scripts side by side: kanji for meaning, hiragana and katakana for sound, and rōmaji for the Latin alphabet. A Japanese person writing a foreign name by ear reaches for katakana, which records the sound but carries no meaning — kanji is the meaning-based art form this site uses instead, in the ateji (当て字) tradition.
No — in everyday Japan, foreign names are written in katakana, which is why it's shown beneath every artwork here. The kanji version is ateji (当て字): an artistic portrait of a name chosen for sound and meaning, not an official translation, so anything permanent should be checked by a native speaker first.
