Tsukinami Village is the home of the eighth gym as well as the two ninja clans. The village pays respect to Tandor's two mighty Pokémon, Aotius and Mutios, as well as Daikatuna and Yatagaryu for aiding ninjas.
The Tsukinami Village Gym is led by Hinata and Kaito, the princess and prince of the separate ninja clans. In this battle, you will face both of them one at a time and one right after the other, so prepare healing items before battling.
The museum houses some interesting artifacts from around Tandor. On the 1st floor, it showcases ninja weapons and artifacts. On the 2nd floor, it houses statues and scrolls of Legendary and pseudo-Legendary Pokémon. At the back, there are statues of the Sea Monster Trio: Baitatao, Leviathao, Krakanao. Standing in front of them is someone taking notes...
The house closest to the town museum is larger than it appears to be from the outside. Unlike other houses in Tsukinami Village, this one features a long hallway with three rooms instead of a stairway.
The first room houses a mother and her daughter. Presenting the child with a Minicorn or Kiricorn will prompt her to give you Kiricornite.
Tsukinami is a combination of tsuki (月 — Japanese for "moon") and nami (波 — Japanese for "wave").
In the dojo, when fighting the third ninja from the right (after completing the Ninja Reunion sidequest), you might get stuck in battle. Upon defeating a pokemon, a next pokemon doesn't get deployed. The only way to get rid of this is to reset the game and load your last save.
