Immersed in a sea of lights and basking in the clamor of tens of thousands of fans at the Kyocera Dome in Osaka, one of Japan's largest venues, JO1 felt a profound fulfillment. The 11-member J-pop group brimmed with gratitude at the realization that the road to their shared dream had stretched wide open.\
Over a video call from Tokyo, vocal leader Junki Kono reminisces about the power of JO1's two November shows at the dome — his former employer. "I was impressed by the fact that I was seeing the same view but from completely different sides – from the perspective of a security guard to the one of an artist," he tells GRAMMY.com. "In the next dome concert, I want our fans to be more excited about our performance, and I want to show them something even better."

This sense of conviction has been ingrained in JO1's DNA since the outset. In 2019, each member bet on faith and auditioned for the inaugural season of "Produce 101 Japan," a television contest aimed at creating a boy group chosen by the public. After 12 nerve-wracking episodes, Takumi Kawanishi, Issei Mamehara, Sho Yonashiro, Ren Kawashiri, Junki Kono, Shosei Ohira, Ruki Shiroiwa, Shion Tsurubo, Sukai Kinjo, Syoya Kimata, and Keigo Sato were crowned JO1. 

However, the arrival of the COVID-19 pandemic forced the newly debuted group to build from scratch while their fans watched them grow from afar. Their tenacity prevailed and, today, JO1 is at a zenith where collective harmony coalesces with individual projects. 

The past 12 months have been a whirlwind journey. JO1 traveled to California for their first performance stateside at KCON LA 2023 and embarked on their second arena tour, which later expanded to Jakarta, Bangkok, Taipei, and Shanghai — their first concerts outside their home country. The tour drew a total of 200,000 attendees and led to a pair of encore shows at the Kyocera Dome. Moreover, aside from new music, their solo artistry was enhanced with acting roles and other creative pursuits.

And the group has no plans to slow down. "I know that many people have a final destination in mind when planning a trip, but for me and the rest of JO1, I'm not quite sure what that final destination is," says Shion Tsurubo. "I believe what's important is that we can enjoy the process and the journey itself."

The next horizon is their eighth extended play, HITCHHIKER. Confident and lively, the six-track production pulsates with versatility, and its funky title track, "Love seeker," is a sonic adventure where to be enamored is the ultimate goal. Or, as JO1's leader Sho Yonashiro puts it, "love for everything. For our songs, our fans, and our members."

As JO1 prepares to continue running "with top speed," they pull the break for a bit and unravel the most important year of their trajectory so far. Fasten your seatbelt.

This interview has been edited for clarity.

Developing Their Artistry From The Stage To The Silver Screen

Ruki Shiroiwa: Seiji, my character [from the film You Made My Dawn], is very free-spirited, but he's also very realistic and believes that there's only life, so he does what he wants and clearly expresses what he thinks. I must say his perspective is very similar to how I live. \
\
JO1's activities are also this way, and each performance is treated as if it's the last one. In a way, I was replicating the strength he has, which somehow also made me feel supported in all the work I did with JO1 [last year]. Seiji felt like a source of power. \
\
Takumi Kawanishi: When [reflecting] on the current music market, it seems like there is a higher demand to create viral or trendy songs. But within that, there is always music and sounds you want to play and things you want to say. [Playing Kiyosumi in Buzzy Noise] made me realize that it's important for me to try my best to showcase the [message] that I want to convey [with my music] as much as possible.

[For my song "Heaven,"] I wrote what Kiyosumi would feel and think, and then tried to capture what I felt as Takumi Kawanishi. I had a slightly strange feeling of being both Kiyosumi and Takumi when I was writing the song, but I think that sentiment aligns with the emotional nature of the film.

Performing Stateside For The First Time At KCON LA 2023

Sukai Kinjo: We couldn't attend KCON LA when we were first invited in 2022 due to [some of us contracting] COVID-19, so when we heard that we could go the following year, we [asked] every member and the surrounding staff to stay indoors and not go outside at all. Going to KCON is a big step, so we asked our managers if we could take a break before the event to rest and [prioritize] our health.

Ren Kawashiri: We performed three songs, with the third one being a cover of "Super" by SEVENTEEN-san, and we felt the crowd's excitement increasing with each performance. Many people might not have known who JO1 was at first, but I think we were able to enjoy ourselves with the audience and have fun on stage that night. We all felt very welcomed.

Shion Tsurubo: There was a moment in the cover of "Super" where we had to lift Syoya as part of the choreography. My first thought was that I couldn't let him fall.

Syoya Kimata: I was very nervous! I could just imagine it would be so bad if I failed on stage [during my first time] in Los Angeles. I took extra care, so I was very happy when I landed [after they threw me into the air], and I continued dancing throughout the performance without worrying or thinking about it.

Junki Kono: I was proud of my members, and we were all satisfied after our performance ended. We loved Los Angeles and we actually did some filming and photoshoots around the city. We met many local people, and it was fantastic. I want to return sometime soon. I miss In-N-Out. [Laughs.]

Expanding Their Musicality On Their Third Album, EQUINOX

Takumi Kawanishi: The "colors" of JO1 have been changing little by little. During the EQUINOX era, we were allowed to produce music with a nostalgic feel, but it also had a "power-up" element. I believe everyone in our group was looking to convey this as well.

Shosei Ohira: This album has a wide range of styles. For instance, "Venus" has elegance in its melody, and "RadioVision" is a pop song with an old-fashioned, retro charm. We also had our unit songs – "Itty Bitty" and "Mad In Love." This is something that we didn't do in our previous releases, so we were able to show a new [artistic] side of JO1.

Sukai Kinjo: I believe that every time we release a new album, my vocal ability has improved a lot compared to the previous one. I will work even harder and try my best to bring my "miracle voice" to the world.

Seeing Asia On The BEYOND THE DARK Tour

Issei Mamehara: It was our first overseas tour, so I was very happy! The experience made me recognize that I love and enjoy performing with our fans, JAM, at a close distance. Jakarta was especially memorable because it was the first show, and even though there were some sound problems, JO1's performance covered it up.

Ruki Shiroiwa: We had some technical issues [in Jakarta] while performing "Venus" that caused the song to stop playing. However, we usually practice during rehearsals in case something like this happens. It became a real situation, so when the sound stopped, we all knew we had to continue dancing. Everyone who gathered in the concert venue also joined us by singing and livened things up, so it feels like a success that we were able to avoid some trouble.

Keigo Sato: The size of the venues was smaller compared to those in Japan, but we could feel the high pressure from the audience, and it was amazing.

Watching Their Dreams Become Reality At The Kyocera Dome

Shosei Ohira: It was our first time stepping onto the Kyocera Dome [as headliners], which was a stage that all the JO1 members admired. The moment I stood on [that stage], I felt my dream come true, and it was an unbelievable time. I experienced many things [in the past], and many people supported me before I got here, so I was really thankful.

Junki Kono: When I was working at the Kyocera Dome, the stage seemed to be shining, and the artists who filled the venue also looked radiant. I remember being impressed by the sound of the concerts — it shook my heart. I don’t know why, but I remember feeling like I could stand on that stage in the future, and I was telling everyone around me, including my colleagues, that I would make it happen.

[Performing at Kyocera Dome with JO1] was the moment when my efforts and words were rewarded. But I also understood that standing at the Kyocera Dome is not a goal but a passing point on the road to my dream. I found a new challenge from this experience — a dome tour.

Sho Yonashiro: When the stage doors opened, I felt like a hero. But at the same time, there was a feeling of nervousness because we were the protagonists [that day]. If we had made a mistake, Ren, our performance leader, would have been angry. [Laughs.]

Ruki Shiroiwa: The concert is now available on Amazon Prime Video in Japan, and I've already watched it. While on stage, I felt that everything went smoothly, and I was really happy. However, looking back, I noticed that there are also areas where we need to improve. In the future, if we perform at the Kyocera Dome [again] or the Tokyo Dome, we would like to increase the quality of the performance. 

Winning The Excellent Work Award At The 65th Japan Record Awards 

Issei Mamehara: During a period when we were looking to make exciting songs, we had the opportunity to do "Trigger," and it received the Excellent Work Award at the Japan Record Awards. We were really honored. I wouldn't go as far as calling it our representative song, but we would like many people to truly listen to it.

Keigo Sato: I'm still skeptical about why "Trigger" wasn't a title track. I knew it was going to go viral. [Laughs.]

Returning To "Kōhaku Uta Gassen," Japan's Biggest End-Of-The-Year Television Special

Sho Yonashiro: "Kōhaku" is a [major] television show in Japan, and we had the opportunity to be invited [to perform] for a second time. There are a lot of K-pop artists coming in [as guests], and we know there are some comparisons between us and them.

All I can think of is that we need to demonstrate we can be competitive and shouldn't be satisfied with our position. After being there for two years, we need to continue expanding our [performance] skills and be more charismatic on stage.

Ren Kawashiri: It would not be an exaggeration to say that our role as top batters [for the White Team] somewhat determined the show's momentum. Back in 2022, we didn't know what we were doing, so we just tried our best, but the second time around, we had more room to think about how to create a good ambience.

Heading Down A New Road With HITCHHIKER 

Keigo Sato: My favorite song [from HITCHHIKER] is "Lied to you" because up until this point, we didn't have a track with this kind of Western-style [flow]. The lyrics talk about heartbreak and the inability to express your feelings, and the singing is really great. It's very similar to an Olivia Rodrigo song.

Junki Kono: The bittersweet atmosphere of [our B-side] "Lemon Candy" illustrates the emotion of "I can do anything for you." These may be extreme words, but I put the message in the lyrics that I feel [about] you that strongly.

When I heard the song, I instantly knew that it was composed by Yonghwa-san [from CNBLUE] because it really conveyed his vibe. He taught me many things during the recording session, such as how to sing with more of my own personality, which made me a little nervous. 

Syoya Kimata: Our title track is called "Love seeker," and I believe our trajectory is like hitchhiking as we search for the love of the audience in Japan and people who don't know about JO1 yet. I hope we can continue spreading our music and gain more recognition, so we will keep working hard to achieve that.

Ren Kawashiri: I feel we have a common understanding that has developed over the past five years. We are taking advantage of the fact that we have 11 members, which, in some cases, may be considered too many people, but we believe that each one of us injects strength into the group.

Steering Towards A Bright Future

Sho Yonashiro: We still feel that we must become more famous – even though we have achieved a lot as a boy group [in Japan]. It's been almost five years since our [formation], and we have gained experience and grown significantly compared to our beginnings. However, when we look outside Japan, many don't know who JO1 is, and I think this is a challenge worth taking over and over again. 

Sukai Kinjo: JO1 is very strong and unique on stage, and that’s where we can show how powerful we are as a group. I think our artistic [essence] resonated well with people in Los Angeles, and we do have the potential to reach more international fans. I believe it will be a matter of time before we go viral around the world. [Laughs.]

Ren Kawashiri: We will be superstars!
