Kobukuro “Mirai” Comics “orange” ver.

This is the 27th single by Kobukuro, a musical duo known for releasing many big hits with catchy yet beautiful harmonies, such as “Sakura” and “Eien ni Tomo ni.” The song was chosen as the theme for the film Orange, which is based on a shoujo manga, and it became a long-running hit alongside the movie’s major success—so many teenage girls have probably heard it.

Featuring piano and a relaxed tempo, it’s easy to sing and highly recommended for karaoke.

If you’re going with friends, try taking on the delicate harmonies like in the original.

Summer rain

In early July, the lingering rainy season often brings days when it’s hot yet raining.

On days like that, how about listening to “Summer rain,” released in 2009? This emotional track is by the folk duo Kobukuro, who made their major debut in 2001 with their first single “YELL ~Eru~/Bell.” Its catchy, memorable melody seems perfect for karaoke, and if you’re up for it, try tackling the harmony parts too!

Kobukuro - Kokoro (Heart)

The song “Kokoro” (“Heart”) is a number that gives you an opportunity to face your own heart.

Released in 2017, it was chosen as the theme song for the film “I’m Taking a Break at Work Now” (Chotto Ima Kara Shigoto Yamete Kuru), and the music video features NAOTO from EXILE and Sandaime J SOUL BROTHERS from EXILE TRIBE.

The track unfolds at a relaxed pace, as if having a gentle conversation with your heart, making it easy to sing without rushing.

If the key feels a bit high, try lowering it a few steps so you can sing more comfortably and freely.

Footsteps of TimeKobukuro19rank/position

Kobukuro – Footsteps of Time

“Footsteps of Time” is a song that makes you feel the happiness of walking through each day with someone special.

Released in 2008, it was used as the theme song for the dramas “Oh! My Girl!!” and “Natsu Uta Drama SP: A Gift of Happiness.” Even those not accustomed to karaoke will find it easy to sing, as you can take your time and savor each word of the lyrics.

If the key feels a bit high, lowering it slightly will let you sing more comfortably while staying immersed in the song’s world.

Some parts of the rhythm may be a little tricky, but don’t worry—if you listen closely to the original track and practice without rushing, you’ll be fine!

Blue BirdKobukuro20rank/position

Kobukuro – Blue Bird

Blue Bird warms the heart with its gentle love, sung over a refreshing melody.

Released in 2011, this song was used as the opening theme for the anime Bakuman.

While the melody itself is easy to get into, the key is a bit high, so if high keys are not your forte, I recommend lowering it a few steps to make it easier to sing.

However, since the song modulates multiple times, be careful about what the next notes will be when you change the key.

Aside from the key changes, the melody is relatively easy to remember and sing, so try listening to the original many times and practicing!
