Japan's fourth-largest city sits at the centre of the country's automotive industry, but almost all of that R&D — Toyota's own city-scale test bed included — happens in neighbouring Toyota City, Kariya and Susono, not inside Nagoya itself. The city's own record is smaller and more recent: a decades-long retrofit that only brought one-driver automatic train operation to its oldest subway line in 2017, a 2026 bus corridor bridging the gap until the Linear Chuo Shinkansen arrives, a prefecture-led automated shuttle pilot that still keeps a safety driver behind the wheel, and municipal open-data and smart-water-meter programmes that are each barely a few years old. It is a working city, not yet a showcase one.

- 🇩🇪 Hamburg: ALIKE Autonomous Ride-Pooling (MOIA ID. Buzz) Same shape of project: a federally/prefecture-backed consortium testing automated shuttles with a safety driver aboard for the full pilot.
- 🇰🇷 Incheon: Hyundai Mobis Level 4 Autonomous Test Drives, Songdo–Yeongjongdo Contrast within the region: Incheon reached Level 4 testing on a similar-length route, while Nagoya's shuttles remain Level 2 with a driver.
- 🇰🇷 Incheon: Incheon Data Portal Same relaunch story a year apart — Incheon rebuilt its portal in Jan 2024, Nagoya in Nov 2024, both without usage figures.
- 🇪🇪 Tallinn: Tallinn Open Data Portal Same municipal open-data model, minus the shared bodik.jp/CKAN backbone Nagoya's catalogue runs on with dozens of Japanese cities.
- 🇨🇴 Medellín: Metroplús Bus Rapid Transit (BRT) & Fleet Telematics Both pair the bus corridor with real-time position tracking — Medellín's via GPS telematics, Nagoya's via rider-facing tracking.
- 🇵🇭 Manila: EDSA Busway (Carousel) Manila's busway also leans on real-time monitoring of its buses, though its cameras track dwell times, not rider positions.
- 🇺🇸 Houston: FIRST — City of Houston's Bayou Flood Early-Warning System Same shape: Houston's FIRST also just publishes flood-inundation maps for officials to act on, not to trigger anything itself.
- 🇨🇳 Tianjin: Automated Waterlogging Monitoring & Early-Warning System Contrast in automation: Tianjin's sensors report every 5 minutes into an automated warning; NICOS just displays readings.
- 🇨🇳 Wuhan: Wuhan Metro Driverless Lines (5, 12 & 21) Contrast in path to automation: Wuhan's Line 5 opened GoA4 driverless day one; Nagoya spent 2015-17 retrofitting its 1957 line.
- 🇮🇳 Kolkata: Green Line CBTC Signalling & Automatic Train Operation (Kolkata Metro) Same shape, different mode: Kolkata added CBTC to its oldest metro's newest line; Nagoya added ATO to its original 1957 line.
- 🇨🇳 Tianjin: Citywide Smart Water Meter Rollout Contrast in speed: Tianjin passed 3 million NB-IoT meters with app-based billing by 2022, years ahead of Nagoya's single-building trials.
- 🇨🇳 Guangzhou: Guangzhou Public Data Open Platform Same move: both portals were rebuilt and relaunched years after their original launch, publishing dataset counts, not usage.
- 🇨🇳 Guangzhou: Guangzhou Bus Rapid Transit Corridor Same dedicated-lane BRT genre, though Guangzhou runs full-time citywide rather than Nagoya's four-day-a-week stopgap corridor.
- 🇯🇵 Osaka: Osaka Water Smart Meters and Remote Reading Same country, same story: a small-area LoRaWAN meter trial running for years with still no citywide rollout date.
