Inquiries About DouDouDoujin

Our Story

This business began when the CEO, who was working as a salaryman at Kadokawa Group, received numerous requests for "permission to use works" from around the world. While many people expressed their desire to use various works, the traditional publishing model, which generates revenue by managing works, made it difficult to grant official permissions. As a result, the CEO often had to either respond with "No" or turn a blind eye.

However, the CEO saw great potential in these requests. He wondered how much wider these works could spread across the globe if a cooperative relationship could be built with people who wished to use them. Driven by the concept of "expanding works through collaboration with fans," he became determined to create a new publishing system. This decision led him to leave Kadokawa Group and start developing the service.

Our Activity

The CEO's family business is a printing company, which led to an initiative to translate manga published on Japanese social media and sell it as magazines overseas.

Through this process, it became evident that some independent manga artists, who already have a large fanbase in Japan, are eager to expand internationally. We continue to feature their works in magazines while also accompanying them to overseas events.

Additionally, we discovered that there are many excellent manga from overseas. By translating these works into Japanese and selling them at Japanese events, we are building trust not only with Japanese manga artists but also with international manga artists. To encourage voice actor participation, we organize contests using our platform.

The results of these contests are published in our magazine, providing voice actors with tangible achievements and expanding opportunities for them to showcase their talents.

The best part was being able to interact indirectly with creators overseas through their works. The internet allows us to connect across distances, so I’d love to see more events that anyone can join and enjoy, and I’d love to participate!

Engaging with Indonesian doujin content sparked my own creativity. I hope to continue building relationships and raising the quality of voice acting as audio works, leading to even better creations for both sides.

I was deeply moved by DouDouDoujin's commitment to supporting derivative works while respecting original creations, helping to spread culture across borders…!

As you know, due to copyright and publishing rights, it’s quite challenging for individuals to add voice to existing manga and publish it online. So, a service that allows adding voice to manga is exactly what I've been looking for…!

If I were to be honest, I’ve always had a strong desire to voice my favorite manga and preserve it as a work of art! I wanted to make the original creators so happy they’d cry, but I’ve kept that feeling bottled up for years. In the end, I won the Original Creator Award for both works I submitted, which was the best proof that the creators were delighted…!! Turning it into a contest, rather than just a simple voice acting play, allowed all participants to pour their pride as performers into creating 'audio works.'
