Hamada Bamyu Bamyu – Nandeyanen-nen [full ver.]
Why-ya-nen-nen, Hamada Bamyu Bamyu

A perfect song for anyone who wants to hype up the afterparty! Released in December 2015 under the alias “Hamada Bamyu Bamyu,” which Masatoshi Hamada of Downtown created as a “little sister” to Kyary Pamyu Pamyu.

It’s an electro-pop tune layered with Hamada’s signature Kansai-ben lyrics—a laugh-out-loud track that’ll put a smile on your face.

The gap is irresistible: Hamada, known for his tough image, honestly sings about wanting to be cute.

Born from a segment on the TV show “Downtown no Gaki no Tsukai ya Arahende!!,” it’s guaranteed to fire up the room when you sing it at karaoke.

As DJ OZMA’s debut track, this song brilliantly captures the weekend’s euphoria and has a magical power that sweeps listeners into a whirlwind of dance in an instant.

Released in March 2006, it debuted at No.

14 on the Oricon charts, then steadily gained popularity and ultimately climbed to No.

4.

Though it’s a cover of a hit Korean song, it radiates its own unique charm with Japanese lyrics and choreography.

It’s the perfect closer for after-parties and events, guaranteed to get people of all ages hyped.

A signature song by Kishidan that vividly captures a night brimming with frenzy and excitement.

Showcasing the group’s unique flair—famous for their pompadours and school-uniform style—this track has been a staple since its release in May 2002, indispensable at after-parties and year-end gatherings.

Its karaoke popularity remains strong, with instantly recognizable phrases and choreography that bring the whole venue together.

Sho Ayanokoji’s powerful vocals pair perfectly with a rock ’n’ roll-infused sound, sweeping listeners into a whirlwind of exhilaration.

It’s the perfect tune for anyone looking to have a great time with friends or colleagues.

Pious Saint!! Loli-God Requiem☆Shigure Ui (9 years old)

[Original Song] Sanctify!! Loli God Requiem☆ / Shigure Ui (9 years old) [IOSYS (Maron & D.watt)]
Solemn Sanctification!! Loli-God Requiem ☆ Shigure Ui (9 years old)

If your after-party is just a tight-knit group of truly close friends and acquaintances, I recommend the curious track “Sanctify!! Loli-God Requiem☆.” It offers a glimpse of a new side of Shigure Ui, who’s active as both an illustrator and a virtual YouTuber.

The lyrics—where she simply hurls insults at the lolita devotees who idolize her as “a bunch of creeps”—pack quite a punch, and the biggest crowd-pleaser is the abundance of call-and-response lines throughout the song.

Those interjections play like a manzai-style back-and-forth, and the more you listen, the funnier and more endearing they become.

It might be fun to practice it as a group routine and spring it as a surprise performance!

JoyfulIkimonogakari

“YELL/Joyful” is Ikimono-gakari’s 15th single, released in 2009 as a double A-side.

Unusually for Ikimono-gakari, vocalist Kiyoe Yoshioka sings while dancing with high energy.

Please have towels ready at the venue so everyone can swing them and dance together.
