Lawson is one of the top convenience store chains in Japan, third to convenience franchise giants 7-Eleven and FamilyMart. All of the usual Japanese convenience store goods, such as magazines, video games, manga, soft drinks, onigiri, pastry roulette and bento are available. Lawson has occasionally collaborated on tie-ins with various companies, including Koei's PlayStation 3 game "Dynasty Warriors 7". In celebration of the 25th anniversary of the manga series "JoJo's Bizarre Adventure", a Lawson store in author Hirohiko Araki's native Sendai was remodeled to look like the "Owson" store that appears in part 4 of the series. In late 2013, a crossover with All Japan Pro Wrestling saw Triple Crown heavyweight wrestling champion Kohei Suwama appear in ads and even work the till for a photo-op in a Tokyo location. In early 2016, a Lawson-sponsored Power Cube was introduced into the online game Ingress. DDM and Kadokawa's Kantai Collection also tapped Lawson in limited promotional materials, featuring character representations of shipgirls such as Kashima in Lawson crew outfits, whose popularity persisted long after the promo.
