Fan Poll: Which J-Pop Idol Has the Most Loyal Fanbase?

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.

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.
