Pisces rises, so Jupiter (traditional ruler of the Pisces) represents favourites Japan. Jupiter in his own sign, placed very close to the 1st house cusp, promises a strong performance from the favourites, especially now Neptune is too far from the 1st house cusp to cause mischief.
However, it the aspect of the Moon which gives the clue to the result: Applying to sextile Jupiter, this is another favourable sign for Japan. At just over 6 degrees for the aspect to perfect, it is possible that the best opportunities will arise for them in extra time.
In the absence of any equivalent testimonies for Mercury, representing Costa Rica, victory for Japan seems the most likely outcome.
