The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
JR Central said in 2024 that 2027 was impossible and that the line would not open before 2034; in 2025 that slipped again to no earlier than 2035, which is what Wikipedia's[2] infobox now gives (citing Asahi Shimbun, 29 October 2025). Dated to the last day of 2035, the earliest year now stated.
Wikipedia confirms the maglev, "originally aimed to begin commercial service...in 2027," was delayed and "is not expected to open until at least 2034," matching the pin's stored date, while also noting a later 2025 update pushed the floor "to no earlier than 2035," suggesting further slippage since the pin's date was recorded.
Railway Journal's own headline, "Chuo Shinkansen opening delayed to 2034," published 2 April 2024, matches the pin's stored date, though the article returned a 403 error and could not be retrieved.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
