This 23-story office building with 2 basement floors features a bookstore with one of the largest sales floor areas in the Kansai region, as well as restaurants and general stores. "Avanza" is derived from the Spanish word "avanzar" (to move forward), and is said to represent the company's determination to move forward powerfully into the 21st century. The facility was jointly developed by Nippon Life Insurance, Mainichi Shimbun, and Dai-ichi Life on the former site of the Mainichi Shimbun Osaka headquarters. Although it is located in the business district of Dojima, it is surrounded by greenery, water, and light, and has an open space of about 7,000 square meters that allows you to feel the changes of the seasons, making it a spacious space. The Dojima Yakushido, located in the plaza on the east side of the building, is an ancient shrine that dates back to the time of Empress Suiko, which is related to the origin of the name "Dojima." Upon completion of the building, the building was redesigned to harmonize with the modern building, consisting of mirror glass and stone.
