As of September 30, 2026. At 1 a.m., SAKANACTION frontman Ichiro Yamaguchi can be heard talking normally for two hours on All Night Nippon. He performs live, streams online, writes music, and tours. From the outside, it is easy to think, “He looks completely fine.” Yet Yamaguchi took an extended break in 2022 after serious health problems and later disclosed that he had depression. Even in 2026, he has continued to describe recurring waves of symptoms. So why return to something as demanding as live radio and concerts? Put his public statements in chronological order and a clear answer appears: this is not a story about getting cured and returning to the old version of himself. It is a story about abandoning the idea of going back and building a new way to work while including the illness in the design.
1. His résumé looks like “mental-resistance +999,” but humans are not RPG characters
Frontman of SAKANACTION. Major hits. Arena shows. Kohaku. A weekly All Night Nippon slot in 2026.
On a game status screen, that looks powerful.
Success. Popularity. Work. Recognition. Fans.
It is tempting to ask: how can someone with all of that still develop depression?
Because people are not RPG characters.
Depression has no access-control rule saying, “Successful musician: condition disabled.” NIMH states that depression can affect people regardless of income, culture, or education, and that genetic, biological, environmental, and psychological factors all play roles. WHO likewise describes depression as emerging from complex interactions among social, psychological, and biological factors.
Success may provide resources and protection in some areas. It is not invincibility armor.
The puzzle disappears once external success and internal tolerance for stress are treated as different variables.
2. In 2022, his body stopped before his desire to make music did
On July 1, 2022, SAKANACTION officially announced that Yamaguchi would take a break.
He had been experiencing extreme fatigue since May. Importantly, the announcement also said that he wanted to continue working as a musician. The team tried to support that intention, but in late June a doctor determined that rest was necessary. Shows and tours were postponed or cancelled.
That distinction matters.
He was not simply saying, “I no longer want to do this.”
He wanted to continue.
His body effectively hit the emergency-stop button first.
Yamaguchi later disclosed that he had depression. In 2024, an NHK documentary described the roughly two years in which he struggled with the illness and noted that recovery had moved forward and backward rather than in a straight line.
This is not a simple story of losing motivation.
It is a story of someone who still wanted to work becoming unable to continue in the old way.
3. The comeback was staged from the beginning
In September 2022, SAKANACTION cancelled the remaining live schedule. In the same announcement, however, the band said Yamaguchi’s activities would gradually restart through appearances on regular programs and similar work.
That is a stepwise return.
Not:
Big arena. “Fully recovered!” Confetti. Done.
Instead:
Talk. Stream. Appear for bounded periods. Gradually widen the range of activity. Then return to physically demanding live performance.
In 2026, Nippon Broadcasting’s president described Yamaguchi’s YouTube talk and singing streams from around 2022 as part of his rehabilitation from depression.
So “he was streaming, therefore he must already have been fine” gets the logic backward.
The streaming itself was part of the route back.
4. By 2024, the goal was no longer “erase the illness, then make music”
NHK followed SAKANACTION’s return to touring in a May 2024 documentary.
The program summarized Yamaguchi’s determination in a striking way: he believed he might be able to create a new musical world precisely because he was now a person living with depression.
That changes what “comeback” means.
Normally, comeback sounds like loading an old save file.
Launch pre-illness Yamaguchi.exe. Restore previous settings. Resume concerts. Complete.
His own framing points elsewhere.
The old save cannot simply be loaded.
So the game continues with a changed character.
The illness is not deleted from the inventory screen. It becomes part of what has to be managed.
Call it New Game Plus.
5. In the first 2026 ANN episode, he almost gave the whole answer
In April 2026, Yamaguchi began hosting the Tuesday late-night edition of All Night Nippon.
People naturally asked whether a two-hour live program every week was too demanding.
He said he would do it while consulting his doctor and adjusting his schedule.
Then he explained the core idea.
He did not believe he could return to who he had been before the illness. Trying to “go back,” he said, made things worse. To move forward, he needed to think about “becoming new.”
He also described taking on his first weekly live-radio regular slot as a good challenge within that process.
That makes the role easier to understand.
ANN is not a certificate proving that he is cured.
It is also a laboratory for a different way of living and working.
He is not trying to perfectly reproduce the pre-illness version of himself. He is testing what the post-illness version can sustainably do.
6. Why radio at all?
Yamaguchi has answered that too.
Before taking the ANN role, he spoke about having been supported by All Night Nippon himself and said he hoped music heard on the radio could become something people rely on when they are weak or suffering.
He also said he wanted songs to come out of the radio program, wanted new listeners to discover SAKANACTION and eventually come to shows, wanted to restore the power of music, and wanted to turn opportunities he genuinely desired into music.
Radio, then, is not an unrelated side job.
Talking, connecting with listeners, receiving reactions, writing songs, and performing live all sit on one line in his creative system.
That also helps explain the apparent paradox of voluntarily returning to public exposure even though public exposure brings criticism.
The internet contains people whose service is free but whose damage output is strangely high.
Visibility brings trolls, attacks, and bad-faith readings.
But for Yamaguchi, visibility also appears to be part of the circuitry through which music is made.
The answer is not to eliminate all exposure. It is to make the exposure manageable enough to remain useful.
7. “He looks energetic” does not mean “the illness is gone”
At the March 2026 ANN lineup event, Yamaguchi said in substance that he was not in complete remission and expected to live with the illness for the long term.
In July, he compared the recurring return of symptoms to the tides and described those waves as part of his new normal.
In September, he said that the return of depression symptoms coincided with another chronic condition, cluster headaches, while touring and producing music. He said he would try not to overdo things and would reduce streaming frequency if necessary.
So his 2026 operating model is not:
Treatment complete. HP full. Factory reset successful.
It is:
There are waves. Read the body. Adjust the schedule. Sometimes reduce output. Keep working when possible.
From the outside, he can sound lively for two hours on radio and perform a concert.
That can be genuinely energetic.
It still does not prove that every symptom has disappeared.
8. Is this rehabilitation? Pretty close — but not rehabilitation toward the old baseline
Because his livestreams were explicitly described as rehabilitation, and because official announcements described a gradual return through regular programs, calling this process “rehabilitation-like” is reasonable.
But it is not simply training to get back to the old score of 100.
The questions are different:
How long can I talk now? How much can I create now? How much live performance can I tolerate? Where do I need to stop? Which habits have to change?
That is closer to redesign than restoration.
In engineering terms, this is not a full restore from backup.
The architecture changes after the failure.
9. And somehow “Shin Takarajima” now feels weirdly appropriate
This section is interpretation, not biography.
Yamaguchi has not said that “Shin Takarajima” was written about recovering from depression. The song predates the illness by years. It would be wrong to rewrite the author’s original intent after the fact.
Still, after hearing his current language about not going back and instead moving forward as a changed person, the song’s deliberate, repetitive sense of forward motion can feel unexpectedly resonant.
No teleportation back to the pre-illness self.
Do not abandon the present self.
If there are waves, take the waves with you.
Do radio. Stream. Write. Play live. Rest when necessary.
Then move again.
Not one giant “FULL RECOVERY” button.
Careful operation, followed by another step forward.
That resonance is probably coincidence.
Which is exactly why it is so satisfying.
10. Conclusion: not “a successful person got depressed,” but “if I cannot go back, I will become new”
The initial questions sound simple.
Why would someone so successful develop depression? Why return to the public eye? Why accept weekly live radio when critics are everywhere? Why continue performing?
Yamaguchi’s own statements are surprisingly consistent when placed on a timeline.
In 2022, his body forced live activity to stop. He then restarted gradually through programs and streams. In 2024, he framed the illness itself as part of the person who would make the next music. In 2026, he explicitly said he would not return to his pre-illness self; he would become new. Radio, streaming, and live performance now operate inside that redesign.
So “a successful musician heroically powered through and came back” is actually the less accurate story.
He stopped trying to power his way back to the old version.
He changed the design around the person who exists now.
No success buff. No instant cure event. No motivational speech that refills HP.
If going back is impossible, become new.
And build that new self, slowly, through radio, streams, concerts, and music.
That is the clearest picture of Ichiro Yamaguchi’s position as of September 2026.
