《舞力全開 Wii 2》（日文名稱：ジャストダンス Wii 2 / 英文名稱：Just Dance Wii 2）是由Ubisoft開發，並由任天堂針對日本市場發行的體感音樂節奏遊戲，於 2012 年7月26日在Wii平台正式推出。是日本地區《Just Dance Wii》的續作，同樣承襲系列一貫輕鬆歡樂、全民同樂的派對遊戲風格，但在曲目數量、操作細節與模式設計上進一步進化，讓玩家能在家裡與親朋好友隨時享受一場熱鬧的跳舞盛宴。

和前作一樣，並沒有設定複雜的故事劇情，而是以「舞蹈嘉年華」的概念為基礎，讓玩家化身派對舞者，跟著螢幕上的舞蹈教學角色，隨著不同曲風與舞步共同律動。整體遊戲氣氛輕鬆愉快，強調娛樂性與互動感，不追求勝負壓力，而是透過動作和節奏感培養現場的熱絡氣氛。

在操作方面，依然運用Wii Remote體感控制器進行動作偵測。需持著Wii Remote，模仿螢幕上的舞者擺出對應動作，遊戲會根據揮動的節奏、角度與準確度給予分數評價。除了按鍵操作，仍大量運用揮動、甩動、指向畫面等體感操作。例如在快節奏的歌曲中，需要快速揮動手臂、跳動或扭腰，甚至雙人對舞或集體動作，創造熱鬧的現場氣氛。雖然偵測範圍仍以右手動作為主，但鼓勵玩家配合全身動作投入舞蹈，讓身體律動與音樂合而為一。

關卡設計部分，同樣採用「歌曲即關卡」的形式，內建40首以上精選曲目，橫跨 J-Pop、動漫歌曲、歐美流行、搖滾、舞曲等多元風格。收錄曲目全面針對日本玩家口味進行優化與在地化，除KARA、AKB48、EXILE等日本人氣偶像團體，還有Perfume、Kara、2PM等當紅藝人，加上部分歐美經典熱門歌曲，像是LMFAO〈Party Rock Anthem〉、Katy Perry〈California Gurls 〉，滿足不同世代、不同音樂品味玩家的需求。每首歌曲皆搭配專屬的舞步編排與背景動畫，風格從搞笑、可愛、時尚到誇張誇耀都有，且分為單人、雙人或四人共舞，甚至還有雙方對抗模式，玩法變化豐富。

此外，新增「消耗卡路里模式」，可記錄跳舞過程中消耗的熱量，適合當作日常運動使用。還可以依據自己設定的目標熱量進行挑戰，透過跳舞娛樂同時兼顧健身需求，成為家庭用戶、年輕女性玩家之間相當受歡迎的功能。還可以瀏覽過往紀錄，確認每日運動量，提升持續挑戰的動力。

在市場評價方面，在日本地區上市後獲得廣泛好評，不僅在首週銷售即突破數萬套，後續也穩定成長，成為Wii平台長銷的體感音樂遊戲之一。玩家與媒體普遍讚賞本作曲目豐富度明顯提升，曲風選擇更多元，尤其對J-Pop、動漫與偶像歌曲愛好者來說吸引力十足。體感操作依然維持簡單易懂，只需持著Wii Remote跟著螢幕動作就能跳舞，即便是不擅長運動或節奏感較差的玩家，也能輕鬆享受。多人模式表現依然出色，是朋友聚會與家庭同樂首選遊戲之一。

不過也有部分評論認為，儘管新增些許功能與曲目，但整體遊戲系統與前作差異不大，畫面表現也仍偏向Wii主機中期水準，若與歐美最新《Just Dance》系列相較，部分動畫、角色建模稍顯陽春。此外，動作偵測系統仍以右手為主，對於追求高精度動作捕捉或專業舞蹈挑戰的玩家來說，仍然偏向休閒娛樂取向。

整體而言，這是兼具歡樂、互動、運動與派對娛樂功能的優秀體感舞蹈遊戲。在前作基礎上增加曲目數量與本地化特色，提升舞蹈模式與熱量紀錄功能，讓玩家在家中就能輕鬆享受音樂與舞蹈的雙重樂趣。無論是喜愛J-Pop、動漫歌曲、歐美流行樂，或是單純想在派對、聚會中炒熱氣氛的人，《舞力全開 Wii 2》是Wii 平台上不可或缺的經典選擇之一。

Just Dance Wii 2 (Japanese Title: ジャストダンス Wii 2 / English Title: Just Dance Wii 2) is a motion-based rhythm music game developed by Ubisoft and published by Nintendo specifically for the Japanese market. It was officially released for the Wii platform on July 26, 2012. As the sequel to Just Dance Wii in Japan, the game continues the series’ signature casual, cheerful, and party-friendly gameplay style, while further evolving in terms of song variety, control details, and game mode designs. It allows players to enjoy a lively dance party at home with family and friends, anytime they like.

Like its predecessor, the game does not feature a complex storyline. Instead, it adopts a "dance carnival" concept where players take on the role of party dancers, following the on-screen dance instructors as they move along with various rhythms and choreographies. The overall atmosphere of the game is lighthearted and fun, focusing on entertainment and interactivity rather than competition, with the aim of building an energetic, lively environment through movement and rhythm.

In terms of controls, the game makes full use of the Wii Remote motion controller to detect player movements. Players hold the Wii Remote and mimic the movements of the on-screen dancer, while the game evaluates their timing, angle, and accuracy, awarding points accordingly. Besides button inputs, players will frequently swing, shake, and point the controller to interact with the game. For example, in fast-paced songs, players need to quickly swing their arms, jump, or twist their waists, with opportunities for dance duets and group routines to create a dynamic, party-like atmosphere. Although the detection primarily focuses on the right hand, the game encourages players to involve their whole bodies, blending physical movement with the music.

As for stage design, the game uses a "one song, one stage" system. It includes over 40 carefully selected tracks spanning a wide range of styles including J-Pop, anime songs, Western pop, rock, and dance music. The tracklist is specially localized for Japanese players, featuring hit Japanese idol groups such as KARA, AKB48, and EXILE, as well as popular artists like Perfume, Kara and 2PM. It also includes select Western hits like LMFAO’s "Party Rock Anthem" and Katy Perry’s "California Gurls , catering to players of different generations and musical tastes. Each song comes with its own unique dance choreography and animated background, ranging in style from humorous, cute, fashionable, to extravagant. The game supports single, double, and four-player co-op dances, along with head-to-head battle modes, offering a rich variety of ways to play.

Additionally, the game introduces a “Calorie Consumption Mode”, which tracks the number of calories burned while dancing, making it suitable for everyday fitness use. Players can set their own calorie-burning goals and challenge themselves through dance, balancing entertainment with exercise. This mode became especially popular among families and young female players. The game also records past workout results, allowing players to check their daily activity and boost motivation for continuous challenges.

In terms of market reception, Just Dance Wii 2 received widespread acclaim after its release in Japan. It sold tens of thousands of copies in its first week, with steady long-term sales, making it one of the Wii platform’s best-selling motion music games. Both players and media praised the game’s expanded tracklist and increased musical variety, especially appealing to fans of J-Pop, anime, and idol music. The motion-based controls remained simple and intuitive — players only needed to hold the Wii Remote and follow the on-screen moves to dance, making it accessible even for those less confident in dancing or rhythm games. Its multiplayer performance was also highly rated, establishing it as a top choice for friends’ gatherings and family entertainment.

However, some reviewers noted that while new features and songs were added, the core game system didn’t differ much from the previous entry, and the graphical quality remained at a mid-era Wii level. Compared to the latest Just Dance titles in the West, some animations and character models appeared relatively simple. In addition, the motion detection system still primarily tracked the right hand, making it more casual and entertainment-focused, rather than a precise motion-tracking experience for hardcore or professional dancers.

Overall, Just Dance Wii 2 is an excellent motion-based dance game that balances fun, interaction, fitness, and party entertainment. Building upon its predecessor, it adds more songs and localized features, enhances dance modes and calorie-tracking options, allowing players to easily enjoy the dual pleasures of music and dancing at home. Whether you're a fan of J-Pop, anime songs, Western pop, or just someone looking to energize a party or gathering, Just Dance Wii 2 remains one of the essential classic titles for the Wii platform.
