Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-5100c134eb860a38 descriptive
recreates the ward's streetscape as a browser- and VR-accessible metaverse
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The May 2020 launch press release describes Virtual Shibuya as "a virtual event venue and a digital twin (mirror world) that expresses the same content in cooperation with the real city of Shibuya." The programme's own overview page provides access via a public URL (https://vcity.au5g.jp/shibuya) and refers to it as a "virtual reality (VR) space," i.e. both web-based and VR access.
Caveat
The sources describe an "urban-linked metaverse" or "digital twin (mirror world)" rather than literally using the word "streetscape," and neither page uses the word "browser" — web access is inferred from the public URL rather than stated outright.

Claim 2 clm-a617cf285be0ebc3 descriptive
attend concerts
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The overview page states the programme "held a variety of entertainment-focused events, including music and talk shows," and that "a total of more than 100 artists, VTubers, anime characters, and more have appeared so far."
Caveat
The source describes "music and talk shows," not literally "concerts."

Claim 3 clm-64c0d3a4751dbb06 descriptive
an annual Halloween festival
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Future Design Shibuya's overview page states the Halloween event has been "held every year around Halloween since 2020." Independent coverage by Tokyo Weekender of the October 24–November 30, 2024 edition notes "this event has been taking place for five years," consistent with an unbroken annual run from 2020 through 2024.
Caveat
The event's branding has varied by year and platform ("au 5G Halloween Festival" per Future Design Shibuya, "Virtual Halloween" in the 2024 Tokyo Weekender coverage, "FIND THE HALLOWEEN SHIBUYA" for the 2025 Roblox edition) even though it is consistently described as the same recurring annual programme.

Claim 4 clm-b7bba9ff1814bbca quantitative
Backed by Shibuya Ward, KDDI and nonprofit Future Design Shibuya since May 2020
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Future Design Shibuya's current overview page states "Lead organizer: Future Design Shibuya /KDDI. Officially recognized: Shibuya Ward." The May 15, 2020 founding press release separately confirms that Shibuya Ward "officially approved [the] distribution platform" as co-sponsor of the launch event, and that the (nonprofit) "General Incorporated Association Future Design Shibuya" organized and directed the project.
Caveat
The founding May 15, 2020 press release lists Cluster Co., Ltd. and Psychic VR Lab Co., Ltd. — not KDDI — as the two technical partners alongside Shibuya Ward and Future Design Shibuya; KDDI's brand ("au 5G") appears in the platform's original event name, and KDDI is confirmed as co-lead organiser only on Future Design Shibuya's later, undated overview page. This entry's operator list omits Cluster Co. and Psychic VR Lab, the two technical partners the founding press release actually names.

Claim 5 clm-381a4df1467b48af quantitative
it has drawn 3M+ cumulative event visits
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Future Design Shibuya's own overview page states "Virtual Shibuya Event participants: Total 3 million people (as of 2023)."
Caveat
The source counts cumulative "participants," not literally "visits," and the figure is explicitly dated "as of 2023" — it is not necessarily current as of this entry's July 2026 verification date. As the impact field itself notes, it is a self-reported operator figure.

Claim 6 clm-2c214d1c41475197 quantitative
expanded onto Roblox in 2025
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
transcosmos' October 17, 2025 announcement confirms the launch of "FIND THE HALLOWEEN SHIBUYA, a Halloween-themed game experience on Roblox," developed together with the "Future Design Shibuya General Incorporated Association," with Shibuya Ward mayor Ken Hasebe providing a supporting comment.
Caveat
The Roblox product is released under its own title ("FIND THE HALLOWEEN SHIBUYA") rather than the "Virtual Shibuya" name itself, though it is organised by the same nonprofit, Future Design Shibuya, as part of the same annual Halloween programming.

Claim 7 clm-2f622e9f4ff6c23c quantitative
Cumulative event participation topped 3 million across Virtual Shibuya programming as of 2023, per organiser Future Design Shibuya
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Matches the operator's own reporting on its overview page: "Virtual Shibuya Event participants: Total 3 million people (as of 2023)."

Claim 8 clm-27a3f177f0413c6b descriptive
a self-reported operator figure, not independently audited
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The 3 million figure appears only on Future Design Shibuya's own official pages, i.e. the organiser reporting on itself. Neither of the entry's other listed sources — Tokyo Weekender's October 2024 Halloween coverage or transcosmos' October 2025 Roblox announcement — reports or independently corroborates any participation count, so the characterization as self-reported and unaudited holds against this entry's full source set.
Caveat
No claim-specific caveat recorded
