In 2026, 'Sangokushi Shinsen' celebrated its 5th anniversary of service.
To commemorate this, the 5th-anniversary song 'Harukaze' (Spring Breeze) was released, featuring vocals by Nami Tamaki and lyrics and composition by Yohei Onishi.
Nami Tamaki, who started playing the game triggered by this collaboration, and Yohei Onishi, who has been playing for 4 years.
As a song that conveys the 'joy of fighting alongside comrades' and 'connections' unique to the two who actually enjoy the game, it has attracted attention from many players.

This time, we interviewed Nami Tamaki and Yohei Onishi about the production background of the 5th-anniversary song 'Harukaze' and the charm they feel while playing 'Sangokushi Shinsen'.
──First, please briefly introduce yourselves.
Tamaki:
Hello everyone. I'm Nami Tamaki.
This time, I had the opportunity to sing the 5th-anniversary song 'Harukaze' for 'Sangokushi Shinsen'.
I am very happy to be involved in such a memorable timing.
Onishi:
Hello everyone.
I'm Yohei Onishi, who was in charge of the lyrics and composition for the 'Sangokushi Shinsen' 5th-anniversary song 'Harukaze'.
I am very honored to be involved in the production of the 5th-anniversary commemorative song in this way.
Since I also play 'Sangokushi Shinsen' myself, it feels truly special that a song I worked on becomes a piece that colors a milestone of the game.
■The bonds and justice the two artists wanted to express through music in the commemorative song 'Harukaze'
──This is your first collaboration with 'Sangokushi Shinsen', Ms. Tamaki. What are your thoughts?
Tamaki:
I've always been interested in the history of the Three Kingdoms and knew about things like the 'Oath of the Peach Garden', but this collaboration gave me a chance to experience its charm once again.
When singing 'Harukaze', I went into the recording hoping to express in my own way the 'feeling of fighting together with comrades' and the 'bonds and justice with comrades' that everyone enjoying 'Sangokushi Shinsen' feels.
──Mr. Onishi, this is your second time participating. What differences did you feel compared to the previous 100 million downloads commemorative song 'Shinsen'?
Onishi:
The previous 'Shinsen' was a song produced with the image of 'renewal'. Since this time is a milestone of the 5th anniversary, I wanted to make a song where you can feel the '5 years' of time accumulated through 'Sangokushi Shinsen', as well as the 'bonds' and 'justice' with comrades. Also, to better express the worldview typical of 'Sangokushi Shinsen', we had a traditional Chinese instrument performance team participate, making efforts so that the atmosphere of the work can be felt from the sound as well.
The previous song had a strong rock flavor, but this time we incorporated a rhythmic arrangement, resulting in a song with a different kind of charm. When I actually saw Ms. Tamaki's performance, she powerfully expressed the worldview, and I felt the charm of the song expanded even further.
■The true charm of 'Sangokushi Shinsen' as told by the two
──Ms. Tamaki, do you usually play games?
Tamaki:
I usually enjoy playing games in my spare time.
Triggered by this collaboration, I also started playing 'Sangokushi Shinsen'. At first, I just thought I'd try it out a little bit. But once I actually started, I found myself completely absorbed in it before I knew it (laughs).
It's really interesting to progress while thinking about strategies, and as I played, there were many moments where I felt, 'The history of the Three Kingdoms is so profound,' and I was drawn in more and more. It's also fun to train warlords and think about formations. Being able to play cooperatively with alliance members is also a charm unique to this game.
I'm still a beginner, but I'm enjoying it while understanding it little by little!
──Mr. Onishi, you have been playing 'Sangokushi Shinsen' for a long time. Do you have any special thoughts about the 5th anniversary?
Onishi:
Five years really goes by in a flash, doesn't it?
I myself have been playing 'Sangokushi Shinsen' for 4 years, so I feel like I've spent a lot of time together with this game. It's completely a part of my life now (laughs).
This game adds new ways to enjoy it with every update, so you never get bored even if you play it for a long time.
I can really feel the dedication of the management team, and I'm very much looking forward to seeing how 'Sangokushi Shinsen' will evolve in the next 5 or 10 years.
──Are there any points you are particularly looking forward to in the 5th anniversary?
Tamaki:
I heard that in the 5th-anniversary event, there are chances to get 50 free recruitment orders and a 5-star warlord in the game.
I'm interested in a warlord named 'Yuan Shu', so I'd be happy if I could draw him (laughs). I'm looking forward to it from now!
Onishi:
There are really various projects for the 5th anniversary, but personally, I'm interested in the 'Civil and Martial Arts Showdown'.
Being able to experience strategic battles while enjoying the knowledge of the Three Kingdoms is something I'm purely interested in as a player.
I'd like to take my time playing while listening to 'Harukaze'.
──Finally, please give a message from both of you.
Tamaki:
Congratulations on the 5th anniversary of 'Sangokushi Shinsen'!
I would be happy if you could listen to 'Harukaze' a lot! I think 'Sangokushi Shinsen' will become even more exciting from now on, so please enjoy it!
Onishi:
I hope that 'Sangokushi Shinsen' will continue to be a work loved by many players.
And I would be happy if 'Harukaze' could also be enjoyed for a long time along with everyone's gaming experience.
