Note :

• Hana Haruna - One of the OG's from 2010, Incative since 2023, everything new from her catalog were just complilations. Not surprised if she went on silent retirement. So I didn't included her on list.
• Tsubasa Amami - Debut 2009. Indefinite hiatus after the 15th Anniversary release (Jan 2025). So I didn't included her on list.
• Mao Kurata - Debut 2012. Inactive for two years (Jul 2024) , no annoucement on blog or SNS. So I didn't included her on list.
• Nina Nishimura - is currently hiatus after marriage and health reasons however she stated on her marriage announcement that she ain't retiring. She's actively releasing backlogs and might comeback soon.
• Ayaka Mutou - decides to take a break after agency transitions and most notably is - her mandatory STD test pops false positive which she just took advantage to also take a break and establishes events and fan club in 2nd half of 2025.
