It was party after mount Fuji hiking, and even though I didn't go this year (because it was Ramadan), the team still invited me to the party (they said that I was the part of the team since the beginning... :-) )
They showed me the pictures during the trip, and it was an eventful trip... too bad that I couldn't join...
Anyway, I'd like to go again next year... if I still in Japan by then... :-)
