This month the Japanese Shogi Association announced new rules for professional shogi games.
The cellphone will be banned and the players can not go outside during the game.
Recently, more powerful Shogi programs have been developed so the Japan Shogi Association is trying to avoid any scandal about players using cellphones. In the recent years there have been some scandals on the chess world related to mobile phone, some players have been banned for using the mobile phone in the toilet looking for a good move. At Shogi games can be very long, some games even takes 2 days to finish so shogi players will need to be isolated until the restart of the game.
