is a tunnel on Tokaido Shinkansen operated by Central Japan Railway Company located between Shin-Fuji Station and Shizuoka Station with total length of 4.934 km. It was built and completed in 1964. It is located after Shin-Fuji station and crossing the Fuji River, westward from Tokyo towards Osaka direction. The 0.294 kPa air pressures within the train cars inside Kanbara tunnel were managed according to the initial plan, preventing any auditory discomfort. It illustrates that the computer simulation outcomes align closely with the experimental data.
Due to the age of the tunnel and the frequent occurrence of earthquakes in Japan, regular renovation & maintenance by 2000 workers in 2015 was carried out at night after the last train has passed, especially on "large-scale renovation works" to prevent cracks from appearing due to vibrations caused when the Shinkansen train runs and to ensure that the shinkansen line is parts of "the safest transportation systems in the world". The last time maintenance was performed on the electrical equipment along the Kanbara Tunnel of the major Tokyo-Osaka Shinkansen line was in January 2023 by Central Nippon Expressway Co., Ltd. (NEXCO).
