No, the Tokyo Gaijin RFC players were not playing out some bizarre fantasy in the bowels of Kabukicho or Roppongi! Nor was this some sadistic pre-game ritual. Girls RFC is another name in a long list of wierd and wierder rugby team names here in Japan.
This match was arranged in the middle of the Tokyo Cup season to give game time to new boys and guys who are still learning the game and regularly "ride the pine". The Tokyo Cup 1st Division is no place to blood new talent or let newbies gain experience. So the Gaijin started this game with what was essentially a 'B' team - rookies, old farts, newbies & a bunch of experienced guys waiting on the bench.
Tokyo Gaijin RFC won this year's Cup Winners Cup after a tight, physical and high scoring final in which both teams would emerge with substantial credit: the Gaijin for keeping a points lead throughout the match, and Tokyo Mandala for chasing it down until the tense final seconds.
