Hey! Say! JUMP

Hey! Say! JUMP is currently active with seven members, representing the latest configuration of the group since Keito Okamoto's departure in 2021 and Yuto Nakajima's announced graduation in 2025. They are celebrated for their vibrant J-pop sound, which has evolved over the years from youthful anthems to more mature pop-rock and dance tracks. Known for their strong stage presence and extensive discography, the group has consistently topped the Oricon charts with their releases.

With over a decade in the industry, Hey! Say! JUMP has built a significant following, reflected in their consistent concert ticket sales and media presence. Their current era is marked by the individual members' expanding activities in acting, variety shows, and solo music, while the group continues to release new music and embark on tours, maintaining their status as a prominent fixture in Japanese entertainment.[edit]

Hey! Say! JUMP was formed by Johnny & Associates in 2007, debuting as a group of ten members, which was the largest debut group in the agency's history at the time. The members were selected from Johnny's Jr. trainees, many of whom had trained for years. Their debut single, Ultra Music Power, released on November 14, 2007, immediately hit number one on the Oricon Weekly Singles Chart and sold over 300,000 copies in its first week. The group's name itself combines "Hey!" with "Say!" from the era name Heisei and "JUMP" for Johnny's Ultra Music Power. At their debut, the group was divided into two sub-units: Hey! Say! BEST, comprising the older members, and Hey! Say! 7, featuring the younger members. This structure allowed for diverse musical explorations and individual member exposure. Early years were marked by intense training, frequent live performances, and establishing their energetic image in the competitive J-pop landscape.

The group's journey wasn't without challenges. In 2011, Ryūtarō Morimoto faced indefinite suspension due to an underage smoking scandal, leading the group to continue as nine members. This period tested their resilience but also seemed to solidify their bond. Keito Okamoto's departure in 2021 to pursue acting marked another transition, reducing the group to seven members. Despite these lineup changes, Hey! Say! JUMP has consistently released music that resonates with their fanbase, demonstrating a remarkable ability to adapt and endure in the dynamic entertainment industry.[edit]

Hey! Say! JUMP's musical style has seen a notable evolution since their 2007 debut. Initially, their sound was characterized by bright, upbeat J-pop, filled with youthful energy and catchy melodies, as heard in early hits like Ultra Music Power and Dreams Come True. Albums like JUMP No. 1 (2010) cemented this energetic, pop-centric foundation.

As the members matured, their music began to incorporate a wider range of genres. By the time of albums like Smart (2014) and Wonder (2015), their sound had become more sophisticated, blending pop with elements of rock, R&B, and electronic dance music. Lyrical themes also shifted, moving from simple expressions of youth to more complex explorations of love, self-discovery, and human connection, evident in works like SENSE or LOVE (2018). Their later releases, such as Fab! -Music speaks.- (2020) and FILMUSIC! (2022), further showcased this maturity, often featuring polished production, cinematic influences, and a deeper narrative depth, reflecting the members' growing individual artistic expressions.[edit]

Hey! Say! JUMP has left a significant mark on the J-pop scene, particularly in shaping the perception of large idol groups. Their formation and success demonstrated the viability of managing and promoting a group with a substantial number of members, each with distinct personalities and roles. The group's fashion sense, often characterized by vibrant colors and trend-setting styles on stage and in music videos, has influenced youth fashion trends across Japan.

Beyond music, the members' individual ventures into acting, television hosting, and modeling have broadened the group's reach. Their involvement in various public service announcements and ambassadorship roles, such as their role in the Tokyo 2020 Olympic and Paralympic Games promotion, highlights their positive influence and integration into mainstream Japanese culture. They've also participated in charity efforts, notably contributing to relief funds for natural disasters, showcasing a commitment to social responsibility that resonates with their fanbase.[edit]

The official fandom name for Hey! Say! JUMP is "JUMPing," a playful extension of the group's name that reflects the energetic performances and the fans' active participation. During concerts, JUMPing fans are known for enthusiastically waving penlights, often coordinating colors to match their favorite member or to create a rainbow effect, symbolizing the group's collective appeal. A common fan chant involves shouting "JUMP!" at key moments during songs or at the end of performances.

Fans actively engage in supporting the group through various projects. A notable example is the significant charity drive organized by fans in 2020, which raised over ¥10 million for COVID-19 relief efforts in the group's name. The group's official lightstick, a penlight with a star-shaped tip, is a staple at concerts, often updated with new designs over the years to symbolize the group's evolution. The absence of a single official fan color, with each member having a designated hue, further encourages a diverse and vibrant fan presentation at events.[edit]

The group's name, "Hey! Say! JUMP," is a clever acronym. "Hey!" is an exclamation of encouragement, "Say!" is a reference to the Heisei era (the period of Japan's Emperor Akihito's reign, during which the group debuted in 2007), and "JUMP" stands for "Johnny's Ultra Music Power." All 28 of their singles released to date have debuted at the number one position on the Oricon Weekly Singles Chart, a remarkable feat that showcases their consistent popularity. In 2017, Hey! Say! JUMP was appointed as official ambassadors for the "Tokyo 2020 Olympic and Paralympic Games" promotional campaign, helping to build excitement for the event. The group's debut concert in 2007 was held at the Tokyo Dome, making them the first Johnny's group to hold a debut concert at such a prestigious venue.[edit]
