Recipe for HappinessNEW!Hirai Dai
It’s the ending theme for the second season of the TV anime “The Apothecary Diaries,” a bittersweet yet warm love song that portrays Jinshi’s feelings for Maomao from his perspective.
In the version performed on THE FIRST TAKE, guitar-and-vocal is joined by piano, percussion, bass, and strings, and the emotional arrangement became a hot topic.
It’s a very relaxed song, and many anime fans might already know it.
For the vocals, the key is to project your voice in the low range of the first verse, and smoothly switch to falsetto in the chorus.
Try to lift the corners of your mouth and sing with a bright tone!
the staircase of days that continues foreverNEW!Hirai Dai
It’s a dramatic love song filled with warm yet powerful messages of love and gratitude that are so characteristic of Dai Hirai! The lyric video on YouTube uses simple visuals to convey the world of the lyrics, deepening the emotional impact of the track.
With an overall vocal range of C#3 to A#4, it sits comfortably for many male singers, so plenty of people will likely find it easy to sing.
At 3 minutes and 14 seconds, the song is also on the shorter side, making it easy to memorize.
For the chorus melody where the song title is sung, if you focus on the initial accent and give it a forward attack, you’ll avoid getting hung up and fall naturally into the rhythm.
The key is to sing it fluidly!
Beautiful DaysNEW!Hirai Dai
This is a cheer song from Dai Hirai, released on March 14, 2025, for people setting off on journeys or embarking on new chapters in life! The overall vocal range is B2–G#4.
The chorus might be a bit high, but the rest sits in a comfortable range and seems easy to sing.
If you can hit high notes in chest voice, it might actually work well to belt a bit in the chorus! Each phrase feels like it steps up a level, so if you finish one phrase and sing the next one bigger, repeating that approach should help the song build more and more.
Sing with conviction and let your voice carry!

Gate of GloryNEW!Hirai Dai
A support song for high school baseball in the summer of 2022, created as the theme song for “Netto Koshien,” it’s a track that encourages the players with the message: “We want you to hold on to hope beyond winning and losing.” With warm words, a gentle vocal tone, and a catchy melody, it’s crafted to resonate not only with high school ballplayers but with many people.
The overall delivery is soft, so you’ll want to sing without forcing it; however, the switch from chest voice to falsetto at the start of the chorus may be tricky.
Try keeping your facial muscles lifted from the beginning to make the transition smoother.
Always aim to resonate in the same spot—both chest and falsetto—around the center of your brow.
Since it uses a lot of breath, be sure to take a solid inhale in advance!
Untitled TodayNEW!Hirai Dai
Hirai Dai’s warm yet powerful singing voice and message resonated with many people, generating a huge response, including surpassing 100 million total streams! The song itself is a positive track that sings about the preciousness of everyday life and hope for the future, featuring gospel-style choruses.
Since there are almost no high notes and it has a bright tone, I think it’s consistently easy to sing at karaoke.
When you sing it, aim for a slightly “going-out” voice and keep your energy a bit higher; that will bring out a brighter tone that matches the song’s vibe.
Because it has a gospel feel, make sure to lock in the rhythm with clap-like sounds in the backing!
Prayer FlowerHirai Dai
“Inoribana,” the famous song by Dai Hirai that became a nationwide hit.
It’s one of his signature works, so many of you have probably heard it.
One reason this song is easy to sing is that its basic vocal range is narrow.
Falsetto appears in the pre-chorus and chorus, but if those parts are too difficult, lower the key and sing them in chest voice.
Since the falsetto is in a low register, you should be able to manage it unless you’re particularly uncomfortable projecting your voice.
Alternatively, raising the key can also work.
Quite a few people have vocal cords that struggle with low falsetto but can produce a clean falsetto at a moderately higher pitch, so keep that in mind.
Slow & EasyHirai Dai
Hirai Dai’s classic “Slow & Easy,” centered on Hawaiian-inspired music, is characterized by its overall acoustic vibe.
The song features a fair amount of falsetto, so it’s not necessarily easy for everyone to sing, but it does have relatively few long sustained notes.
That makes it a good pick for those who aren’t confident with breath control.
In the C section, there’s an advanced technique called “fake,” similar to the kobushi ornamentation in enka.
If that part is hard to sing, I recommend performing it with your own simpler arrangement.
