Case study · Kobe Municipal Transportation Bureau
A municipal subway that warns you before the platform.
The Kobe Municipal Transportation Bureau (神戸市交通局 · KMTB) operates the municipal subway — Seishin-Yamate, Hokushin and Kaigan lines — and the City Bus network. Within Be Smart KOBE it integrates NaviLens at Sannomiya and on the Kaigan Line Misakikoen platform as a fall-prevention layer, together with NPO Ai-Collaboration Kobe, NEXT VISION and Shinohara Denki.

The client
神戸市交通局
The Kobe Municipal Transportation Bureau (神戸市交通局 · KMTB) is the public transport operator of the City of Kobe. It runs the municipal subway (Seishin-Yamate, Hokushin and Kaigan lines) and the City Bus network that structures the city — over 30 metro stations and hundreds of urban buses.
Within the Be Smart KOBE programme, KMTB integrates NaviLens at Sannomiya and at Misakikoen on the Kaigan Line as part of a scheme run by NPO Ai-Collaboration Kobe, NEXT VISION (Kobe Eye Center) and Shinohara Denki.
§ The challenge
Let the subway walk you, not just inform you.
- 01
Making a central-island subway speak
Sannomiya subway (S03) is the gateway to the municipal subway and connects with JR, Hankyu, Hanshin and the Port Liner. The challenge: that a visually impaired person can find the right turnstiles, the right platform and connections on their own — without depending on staff.
- 02
Kaigan Line Misakikoen — zero falls
The Kaigan Line has platforms with tracks on both sides. NaviLens reads from cane in hand several metres away and announces «the platform has tracks on both sides — the train door is here». It is one of Japan's first documented uses of NaviLens as a platform safety layer (転落防止).
- 03
Fitting within Be Smart KOBE
The KMTB deployment is not an isolated pilot: it is part of the City's smart-city programme (Be Smart KOBE), operated by NPO Ai-Collaboration Kobe with NEXT VISION (Kobe Eye Center) and Shinohara Denki. That allows tags and processes to be reused at JR Sannomiya, Port Liner, vending and local commerce.

§ The solution
Tags that warn you before the tracks.
On the Kaigan Line Misakikoen platform, NaviLens reads from several metres away and announces by voice: «the platform has tracks on both sides — the train door is here». It works the same with cane in hand or with a guide dog: the app does not require focusing, only being within range (~30 m).
At Sannomiya subway, tags mark accesses, turnstiles and connections with JR, Hankyu, Hanshin and Port Liner — with the same app that already guides at MTA New York and TMB Barcelona.
§ Beyond wayfinding
Readable vending in-station.
Tags don't stay on the wall: NaviLens also reads the Asahi vending machine on the Iryō Center platform, announcing brand, flavour, price and exact position of each button. The same wayfinding principle applied to micro-commerce inside the station.
The deployment is open to local commerce («café 20 m to your left; konbini 16 m to your right») and can be linked to the KMTB GTFS feed to announce the next train on each platform.

§ Timeline
From Sannomiya to Misakikoen.
- Dec 2021
Official launch in the municipal subway
The Seishin-Yamate Sannomiya subway (KMTB) joins the Be Smart KOBE pilot alongside JR Sannomiya and Port Liner Sannomiya. Printed tags at accesses, turnstiles and tactile pavement; voice and multilingual via NaviLens and NaviLens GO.
- Jan–Mar 2022
Kaigan Line Misakikoen — fall-prevention trial
The City documents the use of tags on the Misakikoen platform to announce «tracks on both sides / train door position». Sessions with cane and guide-dog users, organised by Ai-Collaboration Kobe.
- 2023
Continuity and connection to Port Liner / airport
The municipal subway is connected to the intermodal Sannomiya rollout with Port Liner and the extension to Kobe Airport (Kansai Airports Kobe, 28 Sep 2023). November sees the world-first «airport-to-rail» trial linking KMTB-Port Liner-airport.
§ What they said
What the City of Kobe, Nikkei BP and Kobe Shimbun said.
“Guidance 2D-code tags are installed at JR Sannomiya, the Seishin-Yamate Sannomiya subway, Port Liner Sannomiya, … On the Kaigan Line Misakikoen platform they announce «tracks on both sides of the platform» and «position of the train doors».”
“The City of Kobe is running a trial of route guidance and visually-impaired support using colourful 2D-code tags through end of March 2022. … The tag is readable from within 12 metres.”
“A trial of street-walking support using a smartphone voice guidance system has started in Kobe so that visually impaired people can walk freely on their own.”
§ Results
