Daisei W&T is based out of Komaki city in Aichi prefecture.
The city is home to Mt. Komaki (Komaki yama), the symbol of Komaki city.
Mt. Komaki is a national historic site.
Located at 1, Horinouchi, Komaki city, Aichi prefecture, this hill is in the western region of Komaki city, to the immediate west of the central town area.
The Komakiyama castle is known to be built by NOBUNAGA ODA as his residence. Even now, in the surrounding area of Komaki city, nature is preserved to a great extent and is popular as an oasis for residents.
This is an introduction to Mt. Komaki, which has witnessed the history of the Komaki city from the age of civil war up to now.

Komaki castle was the first castle in Japan constructed using stone walls.

Built in the sixth year of the Eiroku era (1563),
it is the oldest stone walled structure in Japan

It was built to conquer the Mino province.
It was of great importance as a front-line base in the conquest of Mino province.
Owing to its crucial position, the castle was fortified by building a stone wall near the mountain top using huge stones and thus a strong defense was built.
This is said to be the oldest stone wall in Japan.

Komakiyama castle built by NOBUNAGA ODA

Construction of the Komakiyama castle
　
NOBUNAGA ODA built the Komaki castle in the 6th year of the Eiroku era (1563) and shifted his residence to Komaki castle from Kiyosu castle.
This was the time when Nobunaga had already defeated YOSHIMOTO IMAGAWA in the Battle of Okehazama and had eliminated the threat from the east by sealing his alliance with IEYASU of Mikawa.
NOBUNAGA had almost unified the Owari province and repeatedly invaded the Mino province.

As far as the literary evidence goes, NOBUNAGA shifting his residence from Kiyosu to Mt. Komaki has been mentioned in a scene describing Nobunaga’s maneuvers in the first volume of “The chronicle of Lord Nobunaga”. However, there is no mention of the year in which the castle was built.

However, the analysis of ancient documents belonging to the same era, such as epistles and journals that depict the activities of Lord Nobunaga leads to the common belief that the Komakiyama castle was built in the 6th year of the Eiroku era.
The period of 4 years from the invasion of Inabayama castle by Nobunaga in the province of Mino up to his shifting to Gifu is considered as the period of Nobunaga.
