Bluermilet

Singer-songwriter milet, known for her vocals inspired by Western music, has gained widespread popularity.

Among her many hit tunes, the one I especially recommend is “Bluer.” This track is one of her works with a particularly strong Western influence.

As a result, it features advanced vocal techniques—such as ad-libs and falls—that you don’t often hear in Japanese pop.

If you’re looking to level up your detailed techniques, definitely give it a try.

This song is included on Ryokuoushoku Shakai’s fourth studio album, Pink Blue, which was released in May 2023.

The track we’re introducing here, Pink Blue, serves as the album’s title track, and its music video was released ahead of the album.

When singing this song at karaoke, the key points are not only how precisely you can trace the vocal melody, which moves intensely and intricately up and down, but also whether you can deliver with a powerful, resonant tone across both high and low ranges.

Combined with the slightly up-tempo feel, it’s quite a challenging song to sing; however, for those confident in their vocals, it’s one you should definitely try.

Efficiently converting breath into voice is crucial, so study that aspect as well—and be sure to practice carefully so you don’t strain your throat.

The Kouga Ninja ScrollsOnmyo-za

This is Onmyo-za’s 10th single, released in April 2005.

It was used as the opening theme for the TV anime Basilisk: The Kouga Ninja Scrolls.

Set over an uptempo, hard-rock-style backing track, it’s a song that really lets vocalist Kuroneko’s high tones shine.

To sing this track convincingly, it’s important not only to deliver the high notes in your chest voice with openness and ease, but even more crucial is how smoothly you can transition between registers in the chorus sections that switch into falsetto.

Master those seamless register shifts, perform it brilliantly, and bask in the praise from everyone around you!

A bouquet with love Superfly

This is Superfly’s fourth single overall, released in February 2008.

It was used as the theme song for the TBS drama “The Mother of Edison.” Shiho Ochi, the vocalist known for her consistently acclaimed vocal ability, showcases her powerful voice and wide range to the fullest in this signature Superfly track.

If you can sing it as powerfully and dynamically as she does, you’ll undoubtedly be the center of attention at karaoke! Just be careful not to strain your throat on the high notes—if you clamp down, you won’t achieve her expansive, powerful sound and you may end up hurting your voice.

Please take good care.

Runiri

iri is a female singer-songwriter who energizes Japan’s R&B scene with her low-toned vocals and stylish musicality.

She hasn’t been very active in the public eye lately, but she’s continued to release tracks that have earned high praise from hardcore R&B aficionados.

Among her songs, one I especially recommend is “Run.” It blends neo-soul and house, peppered with ad-libs throughout.

It also demands a solid sense of groove, making it a true “Japanese-killer” track—one that’s sure to captivate listeners in Japan.

RIRI is a female singer-songwriter whose musical style evokes Ariana Grande and leaves a strong impression.

Having grown up listening to R&B from a young age, she basically sings her songs in English.

Among her tracks, a particularly challenging one I recommend is “That’s My Baby.” You’ll hear frequent falsetto, R&B essentials like ad-libs and falls, and even mixed voice—advanced vocal techniques appearing throughout the song.

The song “ReawakeR (feat.

Felix of Stray Kids)” is a collaboration between Stray Kids—an idol group popular among women across a wide range of ages—and LiSA, known as a leading figure among anison singers.

This piece is challenging in every respect: rap, sustained long notes, and falsetto.

The falsetto that appears during the sustained notes in the chorus is particularly difficult, requiring you to manage falsetto while maintaining strong volume.
