OVERVIEWThe Company and Its Current Direction

FUKAIKA’S OVERVIEWINTRODUCTIONOpening

FUKAIKA was founded in 2023 by PIEDPIPER, a producer at THINKR's creative studio and label, KAMITSUBAKI STUDIO. It was established to expand the studio's possibilities using methods tailored for the Web3 era, based on the content production expertise THINKR developed in the Web2 space.

Over the past two years, we've collaborated with our observers to create several co-creative projects, advancing efforts such as research and development in the metaverse, virtual live productions linked to it, and Web3-integrated artist production initiatives. As several projects have begun to show results, FUKAIKA's business direction is now entering a new phase.

This page will share the journey of FUKAIKA, from its founding to its future outlook, alongside the background and story behind each project.

FUKAIKA’S OVERVIEWOUR MISSIONThe World Envisioned by FUKAIKA

KAMITSUBAKI VERSEThe KAMITSUBAKI VERSE PROJECT Conceived by FUKAIKA

FUKAIKA's main initiative, the KAMITSUBAKI VERSE PROJECT, was launched as a comprehensive IP project aimed at creating Web3 entertainment by combining KAMITSUBAKI STUDIO's original IP initiatives with new forms of co-creative experiences. At the core of this was the project KAMITSUBAKI City Under Construction.

KAMITUBAKI CITY UNDER CONSTRUCTIONOriginal IP Project: KAMITSUBAKI City Under Construction

In 2019, KAMITSUBAKI STUDIO launched its original IP project: KAMITSUBAKI City Under Construction. Centered on an original story set in the fictional city of KAMITSUBAKI City, the project has expanded through ARGs and multiple game developments.

In September 2022, KAMITSUBAKI DAO was established as a decentralized autonomous organization aimed at co-creating a metaverse based on KAMITSUBAKI City.
The initial funding round attracted over 1,000 supporters. The funds were used for metaverse research and development, the creation of the SINKA LIVE SERIES, and the development and distribution of the NFT project "KAMITSUBAKI Resident Genesis."

And after the launch of the KAMITSUBAKI VERSE PROJECT in 2023, the initiative has aimed to integrate IP development with the Web3 space.

from the KAMITSUBAKI VERSE

This section will showcase the works and initiatives that have emerged from the KAMITSUBAKI VERSE PROJECT.

①KAMITSUBAKI Resident GenesisMinting and Selling of Generative NFT Art

KAMITSUBAKI Resident Genesis is a generative NFT art project that symbolizes one's identity as a resident of KAMITSUBAKI City. Each piece features a unique visual and value, serving as both personal identification and proof of residency within KAMITSUBAKI City.

KAMITSUBAKI Resident Genesis is more than just an NFT art project—it offers holders various utilities and events, while also fostering active engagement within the community.

②SINKA LIVE SERIESIP × Metaverse Experiments Driven by Japan's Top-Tier XR LIVE Performances

In March 2023, KAMITSUBAKI STUDIO launched the virtual live project SINKA LIVE SERIES. As part of the KAMITSUBAKI VERSE PROJECT, this initiative aims to build the story and world of KAMITSUBAKI City through a series of virtual live performances, contributing to the realization of its metaverse integration.

The SINKA ANIMATION PROJECT is one of the major milestones of KAMITSUBAKI City Under Construction, a large-scale initiative that has ultimately led to a TV anime adaptation, confirmed for 2025.

This project aims to fully utilize the 3D assets developed through the SINKA LIVE SERIES to deliver a consistent, high-quality expression of the unique world of KAMITSUBAKI City.
It represents our attempt to further deepen the techniques and forms of expression we've cultivated so far—now through the medium of TV anime.
The anime will also feature members of the virtual artist group V.W.P, depicting an epic story set in KAMITSUBAKI City.

The TV anime KAMITSUBAKI City Under Construction will be an entirely new, original work that draws on the stories woven through previous installments of the KAMITSUBAKI City Under Construction project, including:

KAMITSUBAKI CITY UNDER CONSTRUCTION EMERGENCE
KAMITSUBAKI CITY UNDER CONSTRUCTION NARRATIVE
KAMITSUBAKI CITY ENSEMBLE
KAMITSUBAKI CITY UNDER CONSTRUCTION REGENERATE
KAMITSUBAKI CITY UNDER CONSTRUCTION VIRTUAL REALITY

Set in the world of KAMITSUBAKI City, the story is deeply intertwined with music. We're putting everything into making sure the tale of these girls reaches your heart as a new entertainment experience that transcends the boundary between the real and the virtual.

④Web3 ARTISTS PROJECTWeb3-Integrated Artist Project:
"Girls Revolution Project"

Launched in August 2024, the Girls Revolution Project is both a label and a project. It draws on the concepts FUKAIKA has developed through Web3 technology, aiming to create an experience where observers, artists, music, and stories are organically connected.

This project is centered on two groups: the Xtuber unit SINSEIKI, which transcends the boundary between the virtual and the real, and the virtual singer unit TSUMITOBATSU. With these two units at the center, artists and composers with diverse talents come together, each expressing their individuality to the fullest as they build a unique world deeply intertwined with music and storytelling.

We envisioned the new entertainment experience presented by Girls Revolution Project as a step toward next-generation entertainment, where the real and digital coexist.

02.WE ARE AT
A
TURNING
POINTAbout Our Change in Direction

WE ARE AT A TURNING POINTFUKAIKA
NEXT PHASEBuilding on Ideas Gained from Web3,
We Are Shifting to a New Direction
for the Next Stage

Up until now, FUKAIKA has been exploring Web3 as a starting point in its pursuit of a new economic ecosystem. However, we decided to take a major shift in direction.
Here are some details about the background behind this decision and our new vision moving forward.

From here, I'll outline the outcomes gained through these initiatives and share what lies ahead for the future.

①KAMITSUBAKI CITY PROJECTKAMITSUBAKI VERSE Rebranded as the KAMITSUBAKI CITY PROJECT

KAMITSUBAKI VERSE was born from the fusion of KAMITSUBAKI STUDIO's creativity and the interactive experiences unique to Web3. However, we have decided to renew the project by rebranding its name, direction, and content structure. It will now continue as the "KAMITSUBAKI CITY PROJECT," telling the story of KAMITSUBAKI City through a spirit of co-creation, as shown in the diagram below.

In the renewed KAMITSUBAKI CITY PROJECT, we aim to chart a new path as a unified multimedia project that builds on our experiences gained through Web3. Rather than separating the concepts of Web2 and Web3, the project will continue to expand the multilayered story and world of KAMITSUBAKI City across games, TV anime, novels, and more.

Furthermore, the Girls Revolution Project, which originally launched as a Web3-linked artist initiative, will no longer be bound by the Web3 framework. Moving forward, it will collaborate with the KAMITSUBAKI CITY PROJECT alongside V.W.P., focusing on accelerating its activities as an artist project.
We appreciate your continued support.

②Discord COMMUNITYDiscord COMMUNITY: A Hub for Co-creation

KAMITSUBAKI City Under Construction: Two key servers, the current KAMITSUBAKI STUDIO Official Discord Server (formerly the Kamitsubaki City Under Construction. Official Server) and the KAMITSUBAKI VERSE Server (born from the KAMITSUBAKI DAO decentralized autonomous organization), are continually evolving. These servers serve as dynamic "hubs for co-creation," bringing together people passionate about Kamitsubaki to share diverse perspectives and sensibilities.

The revamped KAMITSUBAKI CITY PROJECT will focus on these two Discord servers and the borderless community thriving within them, aiming to build upon the project's legacy of co-creation and support continued free and creative activities.

As part of the KAMITSUBAKI CITY PROJECT revamp, the KAMITSUBAKI VERSE Server will be renamed the KAMITSUBAKI CO-CREATION Server. It will continue the FiNANCiE token initiatives connected to its origin, KAMITSUBAKI DAO, while also evolving as a “hub for co-creation” with the potential to adapt as the overall project expands.

③KAMITSUBAKI Resident GenesisOngoing Generative NFT Art

KAMITSUBAKI Resident Genesis is a generative NFT art collection featuring unique visuals and meaning. It serves as proof of identity and residency rights within Kamitsubaki City. Its value is guaranteed to remain unchanged, protected as an ongoing right for its holders.

The Discord community acts as the "gateway," offering everyone a place to experience the Kamitsubaki City world setting and start conversations. Beyond this entry point lies KAMITSUBAKI Resident Genesis. It symbolizes the collective role holders play in shaping the story and the city.

Currently, this one-of-a-kind art serves as a symbolic proof of residency. However, as the Kamitsubaki City narrative expands across multiple layers through anime, games, novels, and beyond, the meaning and value embedded in this art also hold the potential for further evolution.

④SINKA LIVE ／ SINKA ANIMATIONShaping Kamitsubaki City Through Live Events and Animation

After considerable trial and error, we feel that SINKA LIVE, and the animation works derived from it, represent our most successful results to date.

SINKA LIVE began as a project focused on metaverse R&D, leading to the emergence of the SINKA ANIMATION PROJECT. The subsequent adaptation of this project into a TV anime is gradually giving form to Kamitsubaki City. Naturally, this doesn't mean everything about the city has been revealed yet.

SINKA LIVE is set to continue long into the future, which will likely allow the Kamitsubaki City world setting to expand further. We remain committed to building the world of Kamitsubaki City through diverse formats, including live events, anime, and games.

⑤METAVERSE R&DShift in Metaverse Concept and R&D

(1)METAVERSE LIVE IN VRCHAT Cutting-Edge Live Experiments in VRChat

The most significant strategic shift outlined in this announcement relates to the metaverse.

To date, our experiments exploring metaverse-like spatial representations have not yet led to the creation of a proprietary metaverse built from the ground up. However, as part of our experiment, we hosted virtual singer CIEL from KAMITSUBAKI STUDIO's first solo concert, titled CIEL 1st VIRTUAL LIVE "Fiction" - Kamitsubaki City AREA 5, on May 18th, 2024. This performance was developed under the banner of SINKA LIVE SERIES ANOTHER STORY, representing a different facet of SINKA LIVE.

This concert was created using VRChat, an existing metaverse platform. As a live performance held within the metaverse, it drew significant attention from creators and observers both inside and outside the virtual industry.

Going forward, rather than pursuing the development of our own metaverse, we aim to focus on building KAMITSUBAKI City through the use of existing platforms such as VRChat.

We plan to continue this series of performances—produced in collaboration with the video production company Eallin Japan—as an ongoing and evolving experiment in new forms of live expression within the metaverse using VRChat.

(2)KAMITUBAKI CITY UNDER CONSTRUCTION VIRTUAL REALITYKAMITSUBAKI City Under Construction. Virtual Reality - In Development with Gugenka

Our venture into VR games can also be seen as a natural extension of our approach to the metaverse.

We are currently hard at work developing KAMITSUBAKI City Under Construction. VIRTUAL REALITY, a VR adventure game co-produced by THINKR and XR creative studio Gugenka. This project marks THINKR’s first full-scale VR-based game and represents a significant challenge for us.

VR game development holds immense potential. From this title, we are also exploring the possibility of expanding into AR, MR, and other forms of experiential entertainment—creating experiences inspired by the metaverse.

We believe that works like this, born as a result of our metaverse-driven efforts, will offer observers even more opportunities to enjoy new and exciting forms of engagement.

03.STORY PROTOTYPINGThe Evolving Story Continues

To our observers who continue to follow and support our creative work — thank you. We are truly grateful.

The strategic shift for FUKAIKA, our Web3-focused initiative, did involve some pain. However, looking back on our journey, what we have gained through this process has been immense.

Above all, this experimental endeavor has reaffirmed how central our observers are to everything we do — a realization that we now value more deeply than ever.

That said, not everything we set out to achieve has been a success.

It is important for us now to humbly acknowledge this fact and place priority on applying the lessons we’ve learned to our future creations.

After several years of moving back and forth between Web2 and Web3, we’ve come to realize that the narrative surrounding “KAMITSUBAKI City” has become overly complex. As a result, we have decided to simplify and renew it under the unified direction of the “KAMITSUBAKI CITY PROJECT.”
The valuable experiences and works produced along the way will be carried forward and integrated into THINKR, allowing us to streamline the project under a single direction. FUKAIKA itself will continue to exist, but in a much smaller form — shifting from a Web3-specialized organization to PIEDPIPER’s personal creative base, continuing to focus on story development and original IP planning.

Our prototyping continues.

We will keep taking on new challenges to deliver fresh value and inspiration to all of you.
Thank you, as always, for your continued support.
