Indeed, there is a rule against perpetual checking, as an extension of the repetition rule. The repetition rule states that if a position is reached for a 4th time, with same pieces in hand and same player to move, the game is no contest, whereafter colors are reversed and a new game is started. Players get to keep whatever remaining time they had, with a minimum time normally granted.

However, if such 4-fold repetition is a result of consecutive checks, with no single non-checking move, then that attacking player is at fault and loses. A player could potentially give dozens of consecutive checks, before the repetition becomes illegal.

Repetition is already rare enough, especially at the amateur level. Very few instances of perpetual check repetition occur. Most people who see it as a possibility deviate the 2nd or 3rd time around, or avoid it altogether. I found only a couple actually pertinent videos on Youtube under the search 連続王手の千日手
