FamilyMart stores sell typical Japanese convenience store goods, including basic grocery items, magazines, manga, soft drinks, alcoholic drinks like sake, nikuman (steamed pork buns), fried chicken, onigiri/omusubi (rice balls), and bento.

[14] FamilyMart shareholders approved the takeover on October 26, and the stock was delisted on November 12, thus leading the completion of the acquisition.

[16] FamilyMart opened its first store in Malaysia at Wisma Lim Foo Yong in Bukit Bintang, Kuala Lumpur on November 11, 2016.

It has become popular because it is the first convenience store selling soft serve ice cream and fresh snacks.

Customers will be able to read the ingredients information on the food or drinks packaging before purchase to ensure hassle-free consuming.

In 2017, Phoenix Petroleum Philippines, Inc., a unit of the Davao-based conglomerate Udenna Corporation, acquired the franchise from the triumvirate; it was completed in 2018.

On November 21, 2019, FamilyMart opened its largest outlet in the world, with an area of 390 square meters (4,200 sq ft), at Udenna Tower in Bonifacio Global City, Taguig.

[31][32]However, several FamilyMart stores in the Philippines have closed since 2022, including the world's largest outlet, due to financial challenges faced by Udenna Corporation founder and owner Dennis Uy.

Despite FamilyMart's effective exit from the venture, they maintained licensing rights and store locations retained the company's name.

[41] Initially the stores were operated in a joint venture with Vietnamese distributor Phu Thai Group, after 2013, both companies went their own way, and Phu Thai Group took over a number of FamilyMart stores and started operating them under its own brand B's Mart.

Beginning in July 2005, FamilyMart began building and opening several stores in Los Angeles, California, under the name Famima!!.

Currently, only 20 of Lawson's stores are equipped with solar equipment, but they plan to expand that number ahead of the July 1, 2012 introduction of a "feed-in tariff system", which the government and electricity companies say guarantees purchases of electricity from renewable sources such as solar or wind generators.

[47] On 30 January 2006, FamilyMart began trials of an automatic cashier station at one of its Tokyo stores in cooperation with Itochu and Toshiba.

Special tags on items in the customer's shopping basket are remotely and instantly sensed at the register.

[48][49] In August 2019, footage emerged of as many as six rats scurrying through a FamilyMart store in Shibuya, near sushi displays and down aisles.

FamilyMart responded by shutting the store, in order to investigate the cause of the problem, and apologised if the "unsanitary" footage had made customers feel "uneasy".
