Pan Pong (also Panpon, Pan-Pon or Pang-Pong) is a hybrid of tennis and ping pong. The name comes from the sound when the ball is being hit from one side to the next, pan - pon - pan - pon and is played on asphalt with racquets made of wood, a soft tennis ball and a net in form a wooden plank. Rules are similar to tennis or ping-pong but is played in shorter matches of 3 games.
The game was invented in 1922, during the Taisho era (1912-1926), on the Hitachi Ltd. factory campus in Japan. Pan-Pon was started as a lunch exercise but has grown into a local sport in Ibaraki Prefecture. Tournaments within Hitachi plants, between plants, and among citizens in Ibaraki prefecture in Japan are organized. Outside of Japan the sport is little known, but tournaments have been organized in Harrodsburg, Kentucky, United States, connected to the Hitachi Automotive plant there.
Pan-pon is played on a rectangular flat court, normally outdoors on asphalt alternatively indoors on plastic floor. The court is 7 x 2.5 m with an inner serve area of 5.5 x 1 meter. The net is made of a 3 meter wooden plank, placed 40 cm above ground.
Racquets are made of wood, 30 x 20 cm and ca 10 mm in thickness. A simple ledge can be mounted on one of the short sides to make it easier to hold.
The ball is an air-pumped rubber ball, size like a tennis ball (ca 70 mm diameter). If the ball is dropped from 1 meter altitude it should bounce back up 50–60 cm if it is correctly pumped.
Before the match a coin is flipped to determine the first server. One of the players will serve to start the game and the serve is hit into the receivers inner serve area without touching the net/plank. The receiver will hit the ball back into the servers court side.
A game consists of a sequence of points played with the same player serving. The game is won by the first player to have won at least four points in total. If the score is 3-3 it is necessary to win with two points. At 4-4 it is enough to win with one point.
The serve is alternated between the players, point by point. The server must stand behind the base line and between the side lines. The receiver can stand at any place in the court. It is not allowed to hit the serve with the racket above the waist. The server only has one attempt to make a successful serve. The receiver is not allowed to hit the ball before it has touched the ground.
If team A meets team B, first player A1 will serve with B1 as receiver. In the following game B1 serves to A2, then A2 against B2, etc.
