Let’s be real for a second: loyalty in the J-Pop world is a thing. Not just a “stream and leave” type of vibe. We’re talking ride-or-die, “I’ve been here since their indie days,” “I bought 12 versions of the same single,” kind of loyalty.
Some fans will wait years for a comeback. Others show up at handshake events like it’s a sacred ritual. And then there are those who still cry when they hear a certain 10-year-old graduation song.
So… we asked the fandom. We hit social media, forums, Discords, even dared to enter idol Twitter and 5ch threads. The question?
Which J-Pop idol has the most loyal fanbase in 2024?
You voted. You debated. Some of you got a little too passionate (bless your hearts). And now, the results are in.
1. Yamada Ryosuke (Hey! Say! JUMP)
Why he’s #1: Yamada fans are next-level faithful. Even as new groups debut left and right, his fanbase holds the line like it’s a mission. They stream. They vote. They show up at the airport with banners in the rain.
Notable Fan Move: His birthday trended in 8 countries—with no comeback. Respect.
Loyalty Rating: 10/10 — Unshakable.
2. Yonezu Kenshi
Why he’s here: Technically not a traditional idol—but his fandom? OBSESSED. And loyal in a very quiet-but-intense way. They buy vinyls, digital, merch, even when he disappears for months.
Notable Fan Move: “Lemon” fans still play the MV like it dropped yesterday.
Loyalty Rating: 9.8/10 — The Cult of Kenshi.
3. Sakura Miyawaki (ex-HKT48, IZ*ONE, now LE SSERAFIM)
Why she made top 3: Her fans literally followed her across three groups, two countries, and two industry systems. Japanese fans stood by her even when she was in Korea full-time.
Notable Fan Move: Flew to Korea to see 5-minute stage performances.
Loyalty Rating: 9.7/10 — Global & Hardcore.
4. King & Prince (Group as a whole, especially fans of Hirano Sho)
Why they’re here: The fandom split when members left, but Sho stans? They stayed. Through heartbreak. Through solo career shifts. Through the mess.
Notable Fan Move: Fans created a “healing support project” after the group changes.
Loyalty Rating: 9.6/10 — Emotionally Devoted.
5. Nogizaka46’s Asuka Saito (Graduated, but not forgotten)
Why she’s still on the list: Asuka may have left the group, but her fans didn’t leave her. They’re still following her fashion, drama, and brand deals like it’s a full-time job.
Notable Fan Move: Every graduation performance is a literal tear-fest.
Loyalty Rating: 9.5/10 — Legendary Loyals.
6. Sayaka Yamamoto (ex-NMB48)
Why she’s on here: From idol center to solo rock queen, her fans adapted and thrived. She went indie and her fans went with her. That’s love.
Notable Fan Move: Self-organized billboard campaigns and indie album sales boosts.
Loyalty Rating: 9.4/10 — True Believers.
7. Fujii Kaze
Why he deserves it: The vibe? Chill. The fans? NOT. They’re constantly hyping his message of self-love, peace, and introverted power. Fandom as soft power.
Notable Fan Move: They treat every Instagram live like a TED Talk.
Loyalty Rating: 9.3/10 — Zen but Deadly Devoted.
8. JO1’s Ren Kawashir
Why he’s ranked: The guy breathes, and TikTok explodes. But it’s not just hype—his fans study every move, fancam, and hairstyle like scholars.
Notable Fan Move: #RenKawashiri trended for a look change.
Loyalty Rating: 9.2/10 — Fashionable Fanatics.
9. Utada Hikaru
Why she still ranks in 2024: Utada’s not out here promoting every week, but when she drops something? The internet shuts down. Lifelong loyalty. OG status.
Notable Fan Move: Every single lyric gets dissected like it’s literature.
Loyalty Rating: 9/10 — Cultural Royalty Respect.
10. INI’s Hiroto
Why he rounds out the list: Hiroto’s fans are young, fast, and deadly organized. They’re on TikTok, YouTube, and fan cafe threads simultaneously.
Notable Fan Move: They got his solo fancam on Korean trending—as a Japanese idol.
Loyalty Rating: 8.9/10 — Rising Legends.
Honorable Mentions:
- Takizawa Hideaki (Legend-tier loyalty)
- Haruka Kaki (Nogi’s new-gen fave)
- Da-iCE’s Sota Hanamura
- Ryujin (ex-Produce 101 Japan The Girls)
- Kyary Pamyu Pamyu (still a niche queen)
What Makes a Fanbase “Loyal,” Anyway?
Here’s what fans voted as signs of TRUE dedication:
- Following their idol after graduation
- Supporting solo or side projects
- Defending them against hate (but not delusionally)
- Buying merch even when broke
- Crying at concerts. Repeatedly.
- Still streaming their debut single like it’s 2020.
