When you find out that Arashi's "Love so sweet" was released in 2007, your sense of time seems to glitch.
It was Heisei 19.
Looking back now, it's quite an old song. Yet, even in 2026, it's still said that "when you think of Arashi, this is what comes to mind." Moreover, it's not just people who watched the drama in real time. People who are about eight years younger also casually say, "Love so sweet is popular."
I think, "You were almost a baby back then, right?"
But that's interesting.
"Love so sweet" has become more than just a hit song from 2007. It has surpassed the nostalgic songs of the real-time generation and has been installed as "Heisei J-POP infrastructure" for generations that came after.
"Love so sweet" is a song from 2007
First, as a fact, "Love so sweet" is a single released by Arashi on February 21, 2007. It is also known as the theme song for the TBS Friday drama "Hana Yori Dango 2 (Returns)."
This is strong.
It's not just a popular idol song, but it is strongly tied to the hit drama of that time. When you listen to the song, not only does the music itself spread, but also the atmosphere of the drama, the Heisei television culture, and the excitement of romantic dramas are reactivated together.
In other words, "Love so sweet" did not spread only as a single piece of music.
It has been re-released into society through multiple channels, including dramas, television, schools, karaoke, weddings, variety shows, nostalgia programs, YouTube, and streaming services.
Strong songs remain with generations that didn't experience them in real time
Truly strong songs are not limited to the real-time generation.
For example, people who were elementary students at the time may remember it as "a song I heard on TV as a child." Those who were high school or college students may remember it as "a song of youth and romantic dramas." Adults may remember it as "a song that was played on TV or by family members."
And for generations that were too young at the time, it comes in through other routes later on.
- Parents listened to it
- It was played many times on TV programs
- Someone sang it at karaoke
- It was used at weddings or events
- I listened to it on YouTube or streaming services
- I saw it in Arashi's representative song rankings
- It was introduced many times in programs looking back on the Heisei era
In this case, the song is no longer just "a song of my generation."
It becomes a song that continues to exist within society.
"Love so sweet" is in this position. Even if you didn't watch Hana Yori Dango in real time, you somehow know it. Even if you don't know all the lyrics, you can feel the atmosphere of the chorus. Just by the intro or the song title, the feeling of a Heisei romantic drama arises.
This is almost like the national anthem of Heisei romantic dramas.
The members of Arashi were also quite young at the time
Another interesting point is the age of the Arashi members themselves.
Arashi made their CD debut on November 3, 1999, with "A・RA・SHI." Looking at the birth dates of the members, their ages at the time of the CD debut were approximately as follows:
| Member | Age at CD Debut |
|---|---|
| Ohno Satoshi | 18 years old |
| Sakurai Sho | 17 years old |
| Aiba Masaki | 16 years old |
| Nishikido Ryo | 16 years old |
| Matsumoto Jun | 16 years old |
Incredible.
The entrance point for a group that would become a national idol for a long time was 16 to 18 years old.
And as of February 2007, when "Love so sweet" was released, the members were still in their early to mid-20s.
| Member | Age at Release of "Love so sweet" |
|---|---|
| Ohno Satoshi | 26 years old |
| Sakurai Sho | 25 years old |
| Aiba Masaki | 24 years old |
| Nishikido Ryo | 23 years old |
| Matsumoto Jun | 23 years old |
In other words, when we were around elementary school age and were soaking in "Hana Yori Dango" and "Love so sweet," the members of Arashi were still quite young.
Looking back now, this is a rather strange feeling.
Although it seems like a national idol group from the Heisei era, in reality, the members were in the middle of transitioning from newcomers to mid-level performers. The songs from that period have remained popular across generations even 20 years later.
The lifespan of the song far exceeds the ages of the members at the time.
Why has "Love so sweet" remained so long?
There are multiple reasons for this.
1. Strong memory of the drama tie-up
It was the theme song for "Hana Yori Dango 2." When the popularity of the drama and the impression of the song are linked, the song goes beyond a single hit.
Every time you listen to the song, you remember the images, characters, and the atmosphere in front of the TV at that time. This is a stronger impact than a single hit in the streaming era.
2. The melody is easy to remember as a "bright memory"
"Love so sweet" is not a dark or heavy song. It is bright, positive, and fits the afterglow of a love story.
Therefore, it is easy to use as a nostalgic song. It is also easy to use at weddings or events, and it is hard to make the atmosphere gloomy in karaoke.
Songs like this are easily reused in society.
3. The group image of Arashi fits well
Arashi became a national group not just through a strong charisma, but also through their approachability, brightness, sense of security, and team spirit.
"Love so sweet" fits well with that image.
It is refreshing, not too pushy, and once heard, it stays in memory. It functions well as an "upbeat representative song" of the group Arashi.
4. Many opportunities for contact with the next generation
Songs that spread widely in the Heisei era's television culture continue to be re-experienced in the Reiwa era through videos, streaming, rankings, special programs, live footage, and social media.
As a result, they reach generations who weren't around when they were released.
I think that people who are eight years younger can say "Love so sweet is popular" because of repeated exposure, not because of real-time memories.
This is not just because the song is strong, but also because it had a pathway to remain in society.
Viewing it as "Heisei J-POP infrastructure"
Some songs go beyond being just hit songs and become infrastructure.
Songs that become infrastructure transcend generations.
Even if you didn't listen to them in real time, you know them. Even if you don't seek them out, you are exposed to them. Someone sings them. They are played on TV. They appear on rankings. They are played in the context of nostalgia.
I think "Love so sweet" is precisely this type.
Water, electricity, Love so sweet.
Of course, this is an exaggeration, but it has become deeply embedded in daily culture.
There are several songs like this in Heisei J-POP. They are songs that remain across generations, not just through real-time hits, but through schools, families, TV, karaoke, and events.
"Love so sweet" is one of the representative examples.
Summary: Why a 2007 song remains relevant in 2026
When you find out that "Love so sweet" is a 2007 song, you are first surprised.
But when you think about it, it makes sense.
This song is not just a hit song from 2007.
- Strong drama context of "Hana Yori Dango 2"
- Image of Arashi, a national group
- Bright and easy to reuse melody
- Opportunities for contact through karaoke, weddings, TV, and streaming
- Symbolic nature that is recalled when looking back on the Heisei era
These factors combined have made it a song that remains across generations.
Therefore, it's not strange that people who were babies at the time of release say "Love so sweet is popular."
In fact, this is precisely the strength of this song.
A song that enters the hearts of people who were born later, not just as a real-time memory song.
That is "Love so sweet."
A 2007 song, yet still relevant in 2026.
Arashi, indeed, was part of the Heisei J-POP infrastructure.
