How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page
Since 2020 the Tokyo Metropolitan Government has fitted lampposts with 5G antennas, Wi-Fi, AI cameras and digital signage as multi-function "smart poles". It began with an agreement with Sumitomo Corporation, whose group company NEC installed two types of pole in Nishi-Shinjuku by the end of June 2020; JTOWER, TEPCO Power Grid and NTT East added 20 more there in 2021. Since 2024 the metropolitan government has funded other bodies to put them up instead of installing them itself, and it publishes a verification report for each site every year.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
The network grew from 2 pilot poles in 2020 to 29 in Nishi-Shinjuku and 31 with Minato Ward by mid-2024. In October 2024 Tokyo selected three subsidy recipients — Meguro City, the Otemachi-Marunouchi-Yurakucho town development council and a private company working with the Tokyo Zoological Park Society — to install poles and sensors from November 2024, in service by March 2025. What each site is testing is published: pedestrian and bicycle counts at a Meguro cycle park, event footfall and security efficiency on Marunouchi Nakadori, congestion data and information delivery at Ueno Zoo's east gate, and administrative advertising and disaster messaging around Akasaka. For the original Nishi-Shinjuku poles, the stated subject of verification is the pole's own revenue and running costs alongside public-interest uses such as heatstroke alerts.
🎓 Lesson
Six years in, the question the city is testing is not what the sensors see but whether the pole can pay for itself. The published verification for the flagship Nishi-Shinjuku site names improving revenue and reducing operating costs as the thing being examined, next to the public-interest messaging; and the metropolitan government has stopped installing poles and started subsidising a ward, a business district association and a private firm to install them. A lamppost with a 5G antenna is a landlord's asset before it is a sensor platform, and the city has been honest enough to publish that as the open question rather than a result.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.
- createdAt previously read 2026-08-28T20:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T02:17:23Z on 2026-08-27; evidence: first appears in commit 82110be64b, committed 2026-08-27T02:17:23Z.
