I found this work exhibited at Design Tide.
The names are written in one of the alphabet of japanese that is called katakana.
This is the alphabet used for foreign words but in advertising for graphic and feeling the alphabet do not follow the standard rules.
This is the katakana chart:

If I want to write my name on my business card I should do like this:
Giacomo should be written using japanese syllabus.
Gia>>Ja (ja is made using shi and ya plus ” which turns sha into ja)
co>>>ko
mo>>mo
and then write
ジャコモ
Done! So it is quite easy to write your name in katakana.
Watch out that many names will change:
Franco will be Fu-ra-n-ko
Marta will be Ma-ru-ta
Paul will be Po-ru or Po-o-ru
