Second round of artist information!

J-POPSix of today's leading artists have been confirmed to perform

<Aile The Shota>

-To the next generation of J-POPSTAR-

In January 2022, he will debut with "AURORA TOKIO" from "BMSG", of which SKY-HI is the CEO.

In November 2024, he released his first album, "REAL POP." In March of this year, he held a solo concert, "Aile The Shota Oneman Live "REAL POP"" at Tokyo Garden Theater, and tickets immediately sold out.

She captivates listeners with her silky voice that blends into the music, lyrics woven with an aesthetic eye, and melodies painted with intuition.

With roots in dance and a penchant for black music, he also possesses a rare musicality that has a high affinity with J-POP; an artist whose "existence is genre" and "existence is music."

 

<Shiba>

In September 2021, she joined Wednesday Campanella as the second leading actress and singer.

"Edison," released in 2010, became a hot topic on social media and the music video has been viewed over 62 million times on YouTube.

On March 16, 2024, she will hold her first successful concert at the Budokan as Wednesday Campanella's Utaha. On the previous day, March 15, she will release her first photo essay, "POEM," a book that tells the story of her past that connects her to who she is today.

In July 2024, he started his solo band career and released his first album, "Utau Youni, Hogarakani," which he wrote and composed himself.

In addition, in July 2023, she will appear in the movie "Ice Cream Fever" and the July NTV drama "The Best Teacher One Year Later, I Was Killed by My Student". In April 2025, she will appear in the movie "Paripi Kongming THE MOVIE", and is expanding her range of activities beyond music to include acting and modeling.

 

<HKT48>

It was launched in Fukuoka in 2011 as the fourth group of AKB48, and made its CD debut in 2013 with "Suki! Suki! Skip!"

The 19th single, "Half Sleeve Angel," will be released on July 23rd this summer.

Currently, performances are being held daily at the permanent theater on the 1st floor of BOSS E・ZO FUKUOKA, next to Mizuho PayPay Dome Fukuoka.

 

<Dios>

Formed in 2021. This new band is the result of the collaboration of three people who have stood out in different scenes: Tanaka, the former member of Boku no Lyric no Bouyomi, Ichika Nito, an up-and-coming guitarist who has been involved in producing songs for Polyphia and Machine Gun Kelly, and Mari Sasano, a track maker/SSW who has also worked on the opening theme songs for popular anime and is linked to Vocaloid and game culture. The name is a play on Dio, a character from Tanaka's favorite manga, JoJo's Bizarre Adventure Part 7: Steel Ball Run, and Dionysus, the god of euphoria and intoxication in Greek mythology. Game music, electronica, R&B, metal—

By fusing their respective musical backgrounds, they continue to release genre-less, highly addictive pop music to the world. Dios, who captures the hearts of listeners with their musicality, emotional words, and beautiful yet poisonous pop music, is attracting attention as a one-of-a-kind existence.

<Leon Shinhama>

Born in Shirai City, Chiba Prefecture. He devoted himself to baseball from elementary, junior high and high school, and his dream for the future was to become a professional baseball player. While attending Chiba Eiwa High School, he was the catcher and captain, and although he made it to the top four in Chiba Prefecture, he was unable to make it to Koshien. In the midst of these setbacks, he was influenced by his father, an enka singer, and aimed to become a singer, making his debut on May 1, 2019, the first day of the Reiwa era. The opening theme song for Detective Conan: The Criminal's Hanzawa-san in 2011, "Catch Me, Tonight," was a huge hit with over 100 million views on TikTok for the "Window Cleaning Dance." He made his first appearance at the 75th NHK Kouhaku Uta Gassen with "Subete Ageyou," produced by Noritake Kinashi and written and composed by George Tokoro. On April 16, 2025, the double A-side single "Fun! Fun! Fun! / Honoo no Kiss" was released. It ranked first in the enka and pop singles ranking (second in the overall chart). "Fun! Fun! Fun!" is the first ending theme for the anime "Detective Conan," and the "WAKI WAKI Dance" in the song has become a hot topic on social media. Currently, Leon Shinhama's First Concert Tour ~Subete Ageyou~ is being held at nine locations nationwide from April.

<Reina Washio>

Her voice is clear and somehow sad, and it grabs the hearts of listeners.

After serving as the vocalist for Flower and E-girls, she began her solo career in 2020.

They have held live shows in Osaka, Tokyo, and other places, and have been active in the music industry, appearing on the popular program THE FIRST TAKE.

In 2024, she left LDH JAPAN and became independent. In addition to her work as a singer, she is also active in a wide range of fields, including launching her own apparel brand, "Luamoda."
