Central Japan Railway, the operator of the Tokaido Shinkansen linking Tokyo and Osaka, is testing a chatbot to help international tourists use the high-speed rail line. The tool, called JRTok-AI, was developed by JR Tokai Information Systems, a JR Tokai subsidiary. Users can access it through a smartphone browser.
The system runs on a model built by a major technology company. Its responses draw on a database maintained by JR Tokai. The database compiles ticketing and fare rules published on the company's website. It reflects even minor updates. The chatbot answers questions about stations, ticket purchases, seating types and baggage rules. It also connects to train operation systems. That link provides the real-time location of a specific Shinkansen train.
While the accuracy of generative AI overall is improving, the issue of "hallucinations" -- where AI sometimes presents incorrect information as the correct answer -- remains. JR Central says it found instances of hallucinations when checking the generative AI service of a major IT company, such as incorrect information about whether trains' oversized luggage areas required a reservation. Information updated in real time, such as train status, requires users to perform steps before reaching search results. Because information is constantly updated, it is difficult for AI to learn.
