Def Tech Popular Song Rankings [2026] (1–10)
My WayDef Tech1rank/position

A heartwarming song that makes you believe the presence of your friends will give you a push.
It’s a track by Def Tech, the duo of Shen, who grew up in Hawaii, and Micro, from Tokyo, included on their 2005 album “Def Tech.” It was featured in a Yokohama Tires commercial and as the theme song for the High School Baseball Championship digest program, selling over 2.5 million copies in total.
Its uniquely soothing sound, known as “Jawaiian reggae,” and lyrics that weave English and Japanese together carry a powerful message: “Believe in your own path and keep moving forward.” This is a song you’ll want to dedicate to friends setting out toward their dreams or companions diving into a new environment.
Catch The WaveDef Tech2rank/position

This track captivates with Shen’s soothing, expansive vocals and Micro’s rhythmic flow, as comfortable as waves breaking on the shore.
Just hearing its refreshing, Hawaii-tinged sound will make your heart feel lighter.
Released in April 2006, it’s the title track of Def Tech’s classic album “Catch The Wave,” which also drew major attention as the theme song for the film “Catch a Wave.” Despite being an indie release, the album became a million seller and dominated the music scene at the time.
It’s a warm work that gently gives you a push when you’re about to take on a challenge.
BoleroDef Tech3rank/position

From here, let me introduce a slightly unusual bolero.
The genre known as the bolero originally refers to pieces in a 3/4-time dance form that emerged from the culture of Spain.
It is said to have been created around 1780 by the dancer Sebastiano Carezo.
This one is Def Tech’s Bolero, which became very famous as the theme song for a Japanese Red Cross commercial.
The song draws its inspiration from Maurice Ravel’s Bolero; although it’s not classical but has a distinctly modern pop/rock flavor, it is still, in its own way, a contemporary bolero.
Irie Got ~A Poem of Thanks~Def Tech4rank/position

Bringing in a refreshing morning right from its intro, this song is Def Tech’s “Irie Got ~Arigatou no Uta~.” Its easy-on-the-ears tempo is perfect for the morning! Born during a journey across Japan in search of stories of gratitude, the song packs heartfelt thanks to loved ones tightly into its lyrics.
Taking time to savor both the melody and the words leaves you feeling very calm.
It’s lovely to start the day with a song that celebrates gratitude, isn’t it?
WeakendsDef Tech5rank/position

Some of you may feel a bit sad that summer is coming to an end.
That’s why I recommend listening to “Weakends.” It’s a track released by Def Tech, and over the gentle sound of a ukulele, it portrays a love that wishes to stay together even after summer is over.
The song has a warm overall feel, so it’s relaxing to listen to and might even blow away those feelings of loneliness.
By the way, the title is a coined word that combines “weekends” and “weak.”
BoleroDef Tech6rank/position

This is the song that was used in a Japanese Red Cross commercial.
The moment I first heard it, its coolness almost made me dizzy.
It’s a reggae-style track that makes you want to listen again and again.
The lyrics sing about a great love that connects people.
Def Tech is a duo of two male artists.
Golden AgeDef Tech7rank/position

A mid-tempo ballad included on the 2011 album “UP.” Its signature, gently flowing, wave-like rap is captivating and becomes increasingly soothing as you listen.
The lyrics sing of hope for the future, giving you the courage to keep moving forward.
Def Tech disbanded in 2007 and reunited in 2010.
This song may have been created after their reunion as a declaration of their resolve to keep progressing.
The opening brings to mind their signature track “My Way,” and perhaps it was structured this way precisely because it embodies their determination for a fresh start.
