Running Izu Peninsula of Izu Kyuko Line is land which thing which was south bottom of the sea volcanic group approximately 20 million years ago collides in Honshu located at the top of the only Philippine Sea plate in Honshu where three plates jostle each other approximately 600,000 years ago, and was completed. Crustal movement, volcanic activity continued, and beautiful scenery which the topography full of rich hot spring and changes brought about was formed afterwards.
It is in area where there is much precipitation geographically eminent in Japan as for the particularly southeast side while Honshu and Mount Amagi which erupted after colliding, and having become the land rise in central part of Izu Peninsula, and spring quenches wasabi field. Blue sky does not rarely open if we withdraw to the south even if it rains in the East Coast.
It is Izu Kyuko Line which can finish running such whole area, but there are Tanikawa and the sea which there is mountain in for traffic company and, contrary to the charm, is exposed etc. which there is wind that there is rain in in to severe environment condition.
As for Izu Kyuko Line, 173 places of bridges (total extension 2.0 kilos) exist 31 places of tunnels (total extension 17.8 kilos) in line of 45.7 kilos to Izukyu-Shimoda Station in the starting point at JR Ito Line Ito Station, and others of the beautiful car window of shoreline expecting the Izu Seven Islands cross valley (bridge) between ridge (tunnel) and ridge (tunnel), and station is established in halfway up a mountain of slope, and even the country that there is few running on plains is rare line.
I apologize for the inconvenience, but vehicles which take the sea breeze, and run in slope in a mountain are serious, and, as for we staff maintaining such a railroad facility, trouble does not die out to customer either.
Greatest and the most relevant duty of railway company is "securing of security", and we repeat various efforts every day to achieve this duty. Put support by fare and country and prefecture that are slightly more expensive than same profession others company that there are severe natural environments to surround facilities reaching the 60th anniversary soon and advances from the opening of business to deterioration, and to have from customer, subsidy from hometown municipalities, premeditatedly facilities supplementary; strong; improve, and will travel while still keeping soundness.
Furthermore, I apologize for the inconvenience, but this will travel to customer when it limits speed depending on climatic condition such as rain or wind temporarily and sometimes stops service for natural disaster while establishing standard, and ensuring the security.
We would like eagerly to have such circumstances understand to customer, and to be available in peace.
