There are no direct trains from Chengdu to Tokyo as the two cities are separated by the East China Sea and the Sea of Japan, necessitating air travel or a combination of rail and sea transport. The most common and efficient way to travel between these cities is by flying from either Chengdu Shuangliu International Airport (CTU) or Chengdu Tianfu International Airport (TFU) to Tokyo's Haneda (HND) or Narita (NRT) airports, a journey that typically takes between 8 and 11 hours including transfers. While both cities possess extensive internal rail and metro networks, any attempt to travel by land would require taking trains across China to a coastal port such as Shanghai or Qingdao, followed by a multi-day ferry crossing to Japan, and then continuing by Shinkansen to Tokyo. Therefore, for practical travel purposes, there is no viable train route connecting Chengdu and Tokyo.
