Just Dance Wii 2 (also known as ジャストダンスWii 2) is the second game in the Japanese series following Just Dance Wii. This game is built in the style of Just Dance 3, but lacks some of its features such as unlockable songs and the shop. Like in Just Dance 3, song lyrics are highlighted light blue when a male is singing and light pink when a female is singing, or both if a male and a female are singing together. This game also includes Breakdown Mode, where the player can skip back and forth through a song in order to learn it better.
In Breakdown Mode, it is not possible to earn points because the word "TUTORIAL" is in the star bar; however, feedback icons still appear if the player dances.
This is the only game to feature Difficulty and Effort ratings of 3+.
However, the rating would return in Just Dance 4 and Just Dance 2019 as 4 (Extreme).
Even though the game takes the style of Just Dance 3, the pictograms are in the style of Just Dance 4.
Also, the Gold Move effect takes the style of Just Dance 3 while the sound effect takes the style of Just Dance 4.
This was also the case for the Beta version of Just Dance 4.
For some unknown reasons, Daddy Cool was found in the game credits, despite it not being in the game, due to the fact that the song was only used for a French contest.
The game's files contain unused English translations which cannot normally be played on a Japanese Wii console that has not been modded.
The conditions for getting medals have not been changed, and the wording of the directions to getting some of the medals between the original English version of Just Dance 3 and the unused English translations of this game are left the same.
For example, one of the medals needs Boogie Wonderland to be danced to get it, but the song is not available in-game.
The sound effect for stars and the Hi-Score icon during the results screen are different than those from Just Dance 3.
During Duet and Dance Crews, a colored arrow will come up when pressing the A button to remind the player which coach they chose.
If the player continues the song after pausing during normal gameplay, or if the player selects a section after pausing in Breakdown Mode, it will go right into the countdown starting with 4. The countdown speed depends on the song’s BPM.
The countdown is also used in Just Dance 4, but it starts at 3.
By connecting a microphone to the Wii, players can sing and dance at the same time.
This is the first game in the entire franchise to offer this mode. The first one in the main series would be Just Dance 2014, and it would appear in every following game until Just Dance 2017.
