Neru Nagahama

Nagahama was born in Nagasaki, Nagasaki Prefecture.^[1] Between the ages of 3 and 7, she lived on Nakadōri Island, a remote part of Nagasaki in the Gotō Islands.^[2]

During high school, Nagahama appeared as a participant in the All Japan High School Quiz Championship, a game show for high school students. She advanced to the prefectural-level championships.^[3]

Nagahama auditioned to be a part of Keyakizaka46; however, despite impressing the judges, she withdrew before the final round of auditions due to her parents' opposition. Later, her parents changed their minds after attending a Nogizaka46 concert in Fukuoka and allowed Nagahama to participate in the new group. With the support of the judges from the auditions, Nagahama officially joined Keyakizaka46 in November 2015 during the group's weekly variety show, Keyakitte, Kakenai? However, she was designated as the sole member of a subgroup named Hiragana Keyakizaka46 (けやき坂46, the exact same name but written in kana). Auditions for the subgroup began soon after.^[4][5]

Nagahama made her musical debut with Keyakizaka46's first single, "Silent Majority", though only appearing on a B-side song, "Noriokureta Bus" (乗り遅れたバス).^[6][7] She made her first title song appearance in the second single, "Sekai ni wa Ai Shika Nai", and also sang a solo song, "Mata Atte Kudasai" (また会ってください).^[8] Although eleven new members joined Hiragana Keyakizaka46 in May 2016, Nagahama was the only one to appear in songs by both the main group and subgroup.^[9] In consideration of both groups' increasing activities and the addition of nine second generation members to Hiragana Keyakizaka46 in August 2017, Nagahama left Hiragana Keyakizaka46 in September 2017 and became part of the main group full-time.^[10]

In December 2017, Kodansha announced that they will be publishing a photo-book featuring Nagahama photographed on the Gotō Islands, her hometown. Nagahama was the first member of Keyakizaka46 to release such a book. The photo-book, titled Kokokara (ここから), sold 98,000 copies in its opening week, a record only topped by Mai Shiraishi's photo-book released earlier in the year.^[11] Her photo-book was also awarded by JR Kyushu for promoting tourism within Kyushu.^[12] Nagahama was also given the title "tourism ambassador" by Nagasaki.^[13]

Nagahama has appeared in all singles up until "Kuroi Hitsuji", and was also included in crossover groups such as Sakamichi AKB (with Nogizaka46 and AKB48) and IZ4648 (with Nogizaka46, AKB48, and Iz One).^[14][15][16] After the release of Kuroi Hitsuji in March 2019, Nagahama announced her resignation from the group, citing personal reasons. She officially left the group on 30 July 2019 with a farewell event at Makuhari Messe.^[17][18]

On July 7, 2020, Nagahama returned to the entertainment industry and joined the regular cast of the documentary/variety show 7RULES [ja], co-produced by Kansai TV and Fuji TV. She also launched her official website and Twitter account.^[19]

In July 2021, Nagahama was appointed the chairperson of the annual Tokyo Idol Festival, succeeding fellow former idol Rino Sashihara.^[20] She was succeeded by Nagi Inoue in 2026.^[21]

Nagahama is the Sustainable Development Goals PR ambassador for NHK,^[22][23] and also the host for the television network's sign language educational shorts, titled Shuwa Shower (手話シャワー, Sign Language Shower) and started in February 2022.^[24] She would make her asadora debut in Maiagare! (2022) as Sakura Yamanaka, who is a Gotō Islands native like herself.^[25]
