From Japan to SL

In the previous article, I wrote a long word, supercalifragilisticexpialidocious from Mary Poppins, but the longest English word is, in my dictionally, pneumonoultramicroscopicsilicovolcanoconiosis, a lung disease caused by micro silicon dust from volcano.
The longest name who I met at Baba is MrSirThomasBonnechance. There is a length limit of 31 letters for the display name but no limit for the user-name. So it could be possible to use the longest Japanese name which is in a Rakugo, Japanese comic monologue.　But in SL, there are two persons named only the first 12 letters. JugemuJugemu.
