History
The area of present-day Tateyama was part of ancient Etchū Province. The village of Tatayama was created on May 12, 1894. It was elevated to town status on January 10, 1954. Until about the end of the Edo period, the Gohyakkoku region was called Takaharano. It originates from a time when village government officials asked the Kaga clan for permission to reclaim an open area of wild fields that was worth five hundred kokudaka, or gohyaku-kokudaka. Development went underway, and permission was granted for the formation of a town in the area. Around the area of Gohyakkoku Tenman Shrine, traffic from north to south formed between Toyama Bay and Mt. Tateyama. from there, they would intersect with streets that ran east to west from the town to central Toyama City. This set the scene for growing areas of agriculture and businesses.
Education
Tateyama has seven public elementary schools and one public middle school operated by the village government. There is one public high school operated by the Toyama Board of Education. The elementary schools are: Tateyama Elementary School, Kamagafuchi Elementary School, Takano Elementary School, Tateyama Chuo Elementary School, Rita Elementary School, Hokubu Elementary School, and Nichuano Elementary School. The middle school and high school are both named Oyama, for the shrines on Tateyama mountain. Until 2016, there was an eighth elementary school called Shinseto Elementary, but it has since been closed due to a low number of attendees as a result of migration away from the mountainous area and towards the center of the main town. Tateyama Town's Oyama Junior High School has been reported by Education Departments to have some of the highest English abilities in Toyama Prefecture.
