As October wraps up and we near the end of 2025, the VocaSphere team have been looking back at some of the exciting news stories to come from the vocal synth world this year! Two of our members had the pleasure of speaking with Kumiko Murayama, President & CEO / Producer of 1st PLACE, the company responsible for vocal synths IA, OИE and HIPPI. We discussed some of the events they have been involved in this year, and found out what fans of IA, OИE and HIPPI can look forward to in the near future! 

── Tanudama: Firstly, we would like to thank you for your presence at Hyper Japan Festival 2025, allowing for never-before-seen concert footage to be enjoyed by UK vocal synth fans. What were your thoughts about the opportunity for IA and OИE to make an appearance at a European event this year? 

── T: I was able to witness the performance at Hyper Japan Festival’s Virtual Theatre for myself, and was amazed at the enthusiasm of everyone in the room. As a longtime vocal synth fan based in the UK, I believe that IA and OИE respectively have a significant fanbase here, as well as across Europe. What do you think about the potential for developing this relationship between IA, OИE and fans here? And not to forget HIPPI of course!

── T: Members of VocaSphere have had the pleasure of participating in various official and fan organised concerts in Japan – it seems that such events celebrating and promoting vocal synths have been growing in popularity overseas in recent years. The team at Vocafest have been a significant proponent here in the UK and Europe, and have demonstrated that people are interested in vocal synth-related in-person concert and DJ experiences. Would you consider more regular collaborations with such fan organisations in the near future? 

── T: I would also like to congratulate you on your IA PARTY A GO-GO KI SE KI China Tour this year! What was it that inspired your team to host such momentous events in Shanghai and Guangzhou? Was there anything which surprised you about the fan reception in China?

── Marumain: Speaking of KI SE KI…

Thank you very much for hosting KI SE KI, both in Japan and China! Considering how seldom full concerts for IA are, we truly appreciate the chance you gave us to even relive past concerts online, and together with other TEAM ARIA members. Still, it begs the question: can we expect IA’s next full-length, offline concert to come soon

── M : Reliving IA’s 10th anniversary concert reminded us of how unique IA’s concerts are compared to other vocal synths. It’s not unusual at all to see her performing with backup dancers, singing bilingually in Japanese and English, and even sharing the stage with human performers! IA’s concerts truly have a style and flare that she can call her own. How did you go about deciding on and shaping IA’s virtual artist identity, influencing how her concerts are?

── M : From CeVIO PARTY to VVV, IA and OИE have been appearing in a lot of collaborative, multi-company concerts with other virtual singers! Seeing them perform and interact with vocal synth characters from other companies has been a real treat! What influenced you to have IA and OИE branch out and collaborate in this way?

── M: Out of pure curiosity, are IA and OИE officially close friends with any other vocal synth characters, such as Yuzuki Yukari? We would love to know what kind of official friendship settings they have with characters outside of 1st PLACE!

── M : We are very, very excited about VOCALOID 6 IA -ARIA ON THE PLANETES-! What factors led to the decision to bring IA back to VOCALOID after 12 years of software on other vocal synth engines?

── T : Of course, one of the most exciting innovations in vocal synth technology has been the development and implementation of AI in voice sampling and processing. The degree of “naturalness” in synthetic voices which can be facilitated by AI is a massive draw, but is there anything in particular that your team are excited to see users attempt with this new software? 

── T : I think that fans particularly enjoy seeing new voice software being released, since they can compare the updated vocals to previous iterations. Some people think that the implementation of quality AI in these ways might inhibit a character vocal’s continued future development – what do you think about this? 

── M : Congratulations on TEAM ARIA’s first anniversary! We love the concept behind TEAM ARIA. Sometimes, vocal synth fans have a difficult time finding like-minded friends and regularly meeting with them offline to enjoy their hobbies together. Thus, the existence of TEAM ARIA, serving as an official hub for IA, OИE and HIPPI fans to gather together and feel like a unified community, is something that we truly support! We were honoured to be among the attendees at the IA 13th & OИE 10th HISTORY ARCHIVES exhibit, meeting face-to-face with fellow community members and celebrating IA and OИE together. What can we expect from TEAM ARIA for the rest of 2025?

── T: I am very much looking forward to some of the events and merchandise releases you have announced as of late; myself and fellow VocaSphere contributor Marumain were able to enjoy the IA/OИE SUMMER 2025 × Gratte event in Animate recently. Are there any plans for similar events on the horizon for IA/OИE/HIPPI that we can look forward to this year?

──T & M : Thank you very much for taking time out of your busy schedule to speak with us, and for the many fascinating insights into the history and exciting future of IA, OИE and HIPPI! We will be sure to spread word of your upcoming endeavours in the hope that we can develop an even stronger community of fans worldwide!  

We would like to extend our warmest thanks to Kumiko Murayama for agreeing to speak with us!

The 1st PLACE team have spoken of their desire to bring more events to fans outside of Japan, such as by expanding the scale of future concerts in China, as well as holding a tour in Europe! Since they would like to organise more offline events for fans to attend, make sure to reach out and share any insights you have to help the TEAM ARIA community grow even further!

We at VocaSphere look forward to future announcements from 1st PLACE, and hope to participate in and cover any upcoming events, both within Japan and abroad!
