Gen Hoshino – SUN (Official Video)

When it comes to the work that catapulted Gen Hoshino to widespread fame, many people probably think of SUN.

I, too, was shocked at the time by how this piece is pop yet shows traces of Black music.

The song’s range is quite wide, from low F# to high A.

Rather than the high notes being difficult, the main challenge is that, despite being centered on low notes, high notes still appear.

That said, the vocal line itself is relatively straightforward, and if you can clear the falsetto in the chorus, you can easily aim for a high score.

In the bridge (C section), a rhythm that slightly accents the off-beats appears, and from there the song modulates into the final big chorus, so if you study this part in advance, you’ll be able to aim for an even higher score.

Gen Hoshino – Koi (Official Video)

Composed by Gen Hoshino as the theme song for the 2016 TV drama “We Married as a Job!” (Nigeru wa Haji da ga Yaku ni Tatsu), this number warmly portrays forms of love hidden in everyday life.

It topped the Billboard Japan Hot 100 for 11 consecutive weeks, and the “Koi Dance” featured in the music video also became a hot topic as the drama’s ending.

Blending the oriental timbre of the erhu with a funky rhythm, it’s an irresistibly danceable pop tune that makes your body move.

Sing it at a company year-end party, and it’s sure to liven up the room—an established crowd-pleaser.

Gen Hoshino – Doraemon (Official Video)

Gen Hoshino’s Doraemon theme song is loved by people of all ages.

The song’s overall vocal range is B2 to F4, which makes it quite easy to sing.

In the chorus, where the “do” sounds continue, it’s very important to lock into the rhythm.

The sections that share the same rhythm and timing are just as important.

It’s best to pronounce the words with a light, detailed delivery rather than too crisply.

In the pre-chorus (B-melody), projecting your voice with a big, expansive feel will enhance your expressiveness.

Try singing with an upbeat, fun energy!

Gen Hoshino – Family Song (Official Video)

Set to a heartwarming melody, this masterpiece gently sings about the small joys of everyday life and the connections between people.

Gen Hoshino delicately depicts scenes like morning light and windowsills, as if capturing familiar moments within a family.

Its message—embracing bonds that go beyond blood ties and accepting the diversifying forms of family with warmth—resonates deep within.

Released in August 2017, the song was used as the theme for the Nippon TV drama “Overprotected Kahoko” and reached No.

1 on the Oricon Weekly Singles Chart.

Its distinctive sound, which skillfully incorporates elements of late-1960s to early-1970s soul music, is another draw.

It’s a gem that stays close to the feeling of wishing happiness for someone important to you, so why not listen to it in a quiet moment alone? Its gentle sound may even move you to tears.

Gen Hoshino – Idea (Official Video)

A song released digitally on August 20, 2018, written specifically as the theme for the NHK morning drama series “Half, Blue.” In karaoke, it’s popular as a track that doesn’t require an overly wide vocal range but shows differences through sense of rhythm and expressiveness.

The tempo is 120, and since it has a band sound, it’s easy to lock into the groove; however, when you get excited while singing, the overall tempo tends to rush.

If you keep a bit of cool composure as you sing, you should be able to stay balanced and keep steady time.

Try to sing with a straight, projected tone without relying too much on falsetto; imagining your voice shooting forward will help you produce sound smoothly without hesitation.

In any case, focus on projecting firmly so your voice stays steady and doesn’t waver!
