Masaki Suda 'Niji' (Rainbow)

Masaki Suda, who is not only an actor but also flourishing as an artist, is a highly popular singer-songwriter, especially among men in their 20s.

“Niji” is one of his works that I particularly recommend.

It’s an orthodox J-POP song, but you might feel it sits a bit on the higher side.

That’s because Suda’s natural vocal tone is high, not because the song’s range is especially wide.

Don’t worry about sticking to the original key—find a key that’s comfortable for you and give it a try.

Sugar Song and Bitter StepUNISON SQUARE GARDEN16rank/position

UNISON SQUARE GARDEN “Sugar Song and Bitter Step” Live Music Video

It’s a signature song by the rock band UNISON SQUARE GARDEN.

It’s upbeat and seems like it would really heat up a karaoke session! The song was written specifically as the theme for the anime Blood Blockade Battlefront, so anime fans are probably very familiar with it.

The key is high for men, but for women it might be at a more comfortable range to sing.

Is that okay?RADWIMPS17rank/position

RADWIMPS – Is That Alright? 2017 ver. [Official Music Video]

One song that has earned strong support from many RADWIMPS fans is “Iindesuka?” That’s because this track holds special memories: a self-cover was released a decade later, and its music video was filmed with gathered fans.

The lyrics are also a major reason for its popularity.

Repeating the phrase in the title, the song conveys the wonder of being alive.

With its relaxed yet lively vibe, it should be easy to sing even for those who aren’t into ballads or intense tracks.

RPGSEKAI NO OWARI18rank/position

SEKAI NO OWARI「RPG」

SEKAI NO OWARI’s classic song “RPG.” This work, which could be called the culmination of the band’s fantastical musical style from their early days, is something anyone born in the Heisei era has probably heard at least once.

Surprisingly, the song’s vocal range is quite narrow, spanning from mid1 C# to hi A.

Since the frequently used notes are also on the lower side, even men with lower voices can sing it without issue if they drop the key.

If you want to boost the quality, try mixing in breaths like Fukase does—doing so will really liven things up at karaoke.

SEKAI NO OWARI「Habit」

SEKAI NO OWARI’s hit song “Habit.” Many listeners were likely astonished by this track, which departs from their usual fantastical worldview and instead delivers somewhat caustic, realistic lyrics.

As the groove is emphasized throughout, the song sits within a generally standard vocal range for a SEKAI NO OWARI track, from mid1 C to mid2 F.

However, since the highest note (mid2 F) appears fairly frequently, it may be better to lower the key slightly depending on the singer’s range.

While it’s overall on the easier side, there are several rap-like sections, so it’s recommended to firmly memorize the flow that matches the lyrics.

[AKASAKI] Bunny Girl (Lyric Video)

AKASAKI’s hit song “Bunny Girl,” which went viral nationwide.

The vocal range in this track is from mid1 C to mid2 G, which is quite narrow for recent Japanese pop.

There’s a key change in the final chorus, but even so, the overall pitch movement is minimal, making it exceptionally easy to sing.

The vocal line also has gentle rises and falls, so it’s recommended for people who want to get the crowd going even if they’re not very confident in their singing.

If you want to sound more polished, try incorporating overtone techniques to add richness to the low–mid range.
