The Tower of Waters (Japanese: みずの塔Tower of Water) is a landmark on the Isle of Armor in the Galarregion. It is one of the Towers of Two Fists, and it is where the player goes during The Isle of Armor Expansion Pass if they wish to evolve their Kubfu into a Rapid Strike StyleUrshifu. This can be achieved by defeating all the Trainers in the tower and having Kubfu examine the Scroll of Waters on the top floor. The player is only allowed to enter the tower if Kubfu is the only Pokémon in their party. However, if the player doesn't have Kubfu in their party or Box, they can climb the tower with any Pokémon.
If the player chooses to train Kubfu here, the Tower of Darkness becomes inaccessible to them.
Tower of Waters was introduced as a Stadium card in the Pokémon Trading Card Game during the English Sword & Shield Series (the Japanese Sword & Shield Era). It was first released in the Japanese Rapid Strike Master expansion and the English Battle Styles expansion, with artwork by 5ban Graphics. It makes the Retreat Cost of all Rapid Strike Pokémon in play two Energy less.
