The club has financial backing from Mercari, a Japanese e-commerce company. Since the J.League's creation and introduction of professional Japanese football in 1993, Kashima have proven themselves to be by far Japan's most successful football club in terms of trophies won, having won the J.League title a record eight times, the J.League Cup a record six times and the Emperor's Cup five times for an unprecedented nineteen major domestic titles. Kashima became Asian champions for the first and most recent time as they won the AFC Champions League in 2018. Kashima are also one of only two clubs to have competed in Japan's professional top-flight football every year since its inception (the other being Yokohama F. Marinos). Name origin The name Antlers is derived from the city name, Kashima, which literally means "deer island". History The name 'Antlers' is derived from the city of Kashima (鹿嶋), which literally translates to 'Deer Island'. The club crest not only resembles deer antlers but it also reflects the image of rose thorn as it is the official flower of Ibaraki, the home prefecture of the club. Deer are amiable animals and are viewed in some religions as spiritual messengers. In fact, Kashima Shrine, one of the most famous shrines in Japan and located in close proximity to the club headquarters, have kept and raised deer for more than 1,300 years as spiritual symbol. Deer are affectionate animals but are also known for their courageous character as they battle each other head-to-head with lethal antlers. Founded in 1947 as Sumitomo Metal Industries Factory Football Club in Osaka and moved to Kashima, Ibaraki in 1975. It played in the semi-professional Japan Soccer League (JSL). They were promoted to the JSL's top flight in 1984, but never made much of an impact, going down in 1985/86, returning in 1986/87 and going down again in 1988/89. Its last standing in the JSL was 2nd in the Second Division for 1991/92. After the formation of the fully professional J.League, Sumitomo, like all other clubs, stripped the corporate brand from the club's name and reformed as the Kashima Antlers. Kashima was essentially promoted to the new top flight, as many JSL First Division clubs decided to relegate themselves being unprepared for professionalism. (Of the original
