Yonashiro Sho is the eldest and the leader of JO1. He is well-known for loving to exercise and having a lot of muscles, especially his toned six-pack. Although he might look the toughest, he is seen as the gentle “mother” of the group because he loves to take care of others and is very mature. The members can also easily rely on him with his calm personality and good talking skills.

Before auditioning for Produce 101 Japan, Sho moved to Tokyo from Okinawa to study at university. He was a student in management in hopes of becoming a self-producer. Aside from his studies, he was actively pursuing his dream of becoming a singer. Some of his past videos of his singing can be found on YouTube. He is said to have learned how to sing by himself without any professional help. He also did not have experience dancing before Produce 101.

As an ex-professional backup dancer, Kawashiri Ren has a lot of experience dancing with Seventeen, Wanna One, SMAP, and Tomohisa Yamashita. However, he did not want to spend his life only as a backup dancer, so he joined Produce 101 Japan.

In Produce 101, he was known as “King Ren” because of his superb dancing skills and was chosen by other trainees to be the center for many performances, including the theme song “TSUKAME ~It’s Coming~.” He also was a dance instructor, so he often strictly assists JO1 during their dance lessons as a dance leader. On the other hand, he had no prior singing experience, so he seemed to have struggled with that during Produce 101.

However, his sharp image as a dancer contrasts his personality. Ren is known to have a very bright character and laughs a lot. He has also shown talent in quiz shows. He likes to play games and do magic tricks during his free time as well.

Shiroiwa Ruki followed his dream of becoming an idol as early as elementary school. He was a part of Johnnys’ Jr., under a famous company called Johnny’s Entertainment for young Japanese male idol trainees. He was also a member of an underground idol group. However, Produce 101 Japan was his last chance to become an idol. Since he had been training for a long time, though, he was able to steal a lot of hearts with his refined performance skills.

Ruki is called “prince” by many fans for his looks and because he is seen as the ultimate idol. He is also always very calm and composed. He gets shy when meeting new people, but other members say he is amusing and talks a lot, which may be a side that he has not shown fans yet. He is also famous for showing plenty of love towards the fandom, JAMs.

Despite his princelike features, he has a childish side like his fear of bugs and loving foods that children would like, which are also his charms.

Recently, he has been appearing in the popular YouTube series “THE FIRST TAKE.” In these solo videos, Junki showcases his raw, powerful vocals by singing songs in one take.

Even though Junki is one of the members with the best vocals, he had no prior professional experience singing and dancing. Before joining Produce 101 Japan, he was a student from a prestigious university in the middle of job hunting. The more he practiced, though, he was able to show his speedy improvement. He also loves to work out and play soccer, so his great reflexes may have contributed to his dancing skills, which he was struggling with mainly.

He frequently mentions his lack of variety in his vocabulary, so he may not be the most talkative, but his silly and unique character generates many laughs, making him one of the funniest members of JO1. Although he has an unexpected side, Keigo is also very kind and gentle, so he is seen as a motherly figure by others.

Keigo originally dreamed of becoming a hairdresser, but he decided to audition for Produce 101 Japan instead. He was once a trainee at EXPG (EXILE PROFESSIONAL GYM) at Nagoya. He has experience modeling and is also known for having a good sense of style because of his choice of clothing and slender figure.

Like some of the other members, he had no experience dancing and singing professionally, but he was placed in the highest A rank in the television program with great potential. One of his biggest strengths was his expressions during performing. In Produce 101, the other trainees voted for him as the trainee with the best visuals.

Takumi is very dedicated to anything he is passionate about, which is a part of his overflowing star quality. Among the JO1 members, he can be very dependent on others and a little goofy, so his nickname is “princess.” He also loves to keep everything clean such as his room.

When he was in high school, Takumi was the head of the baseball team. He has shown his talent in numerous variety programs. He can also beatbox and do handsprings. During his free time, he likes watching movies.

Before joining Produce 101 Japan, he was attending a university focused on clothing and accessories. Sometimes he does the other members’ makeup as well. Like this, he is very caring, as he tends to put others before himself. On the other hand, when he is up on stage, he is an entirely different person with a different aura.

When he was younger, Syoya attended classes at a dance school in Nagoya called Funk Kid. This school is notable for having alumni that became professional stage actors and idols. Although Syoya also wanted to become an idol, he was embarrassed to say it out loud. In JO1, he is mainly in charge of dancing and rapping, but he originally wanted to sing.

Ohira Shosei’s nickname is “Angel.” By the other members, he is like a little brother and is loved by his older brothers. His innocent-looking visuals with his gentle way of talking contrasts the way he performs on stage. He can be very manly and powerful or sweet and soft according to the mood of the song.

Like Keigo, Shosei was also a trainee at EXPG, but he was based in Kyoto. At EXPG, he was in a unit called EXPG SWORD, and he did dance performances using a samurai sword. With his passion for dancing, he once studied dancing in America when he was in high school. Since he never really got a chance to debut as an idol, he saw Produce 101 Japan as his last opportunity.

Kinjo Sukai is a member who is usually very calm and maintains a poker face. However, behind his poker face, he is known to be very passionate and charming. Although he is one of the younger members in JO1, his companionship and ability to say his advice even to those older than him make him very mature. The kanji characters for Sukai means “blue sea,” and his parents apparently named him after thinking of the scenery of Okinawa where they are from.

As someone who finished his education and was already working, Sukai is another member who did not have any experience dancing or singing. He struggled in Produce 101 Japan by starting off in the F rank. In spite of this, he improved and continues to improve his dancing by having support from his karate skills and singing with his appealing low, husky tone.

Sukai’s other skills are playing ball games and walking along the beach. In his free time, he likes to watch movies and listen to music.

Although he trained in Korea after quitting high school, he was unable to debut. By continuing to chase his dreams of debuting as an idol, he decided to audition for Produce 101 Japan.

Shion’s cool aura and low rapping voice are some of his charms. His energetic and powerful dancing is also another distinctive feature. Although he may seem to be boyish and have a serious personality, he also has a very soft side, like when he cried with trainees eliminated from Produce 101 or when he shows a lot of affection for his family.

Shion had been a swimmer for around 10 years. His other hobbies are mostly music-related, like singing, listening to music, and dancing, but he also loves to play video games. He can also speak basic Korean from training in Korea.
