車内放送の小規模ではない変更が9年ぶりに感じます It feels like the first time in 9 years that there has been a not-so-small change in the in-car announcement. For example, station name information(例えば、駅名案内です), ○○ Station. →○○. N01-17(Varies by station/駅ごとに異なります). 当時は駅ナンバリングが導入完了、東西線が開業しました At that time, station numbering had been introduced and the Tozai Line began operating.
