history 

Spam musubi is a form of musubi, which originally came from Hawaii. It was a popular item among the lunchboxes of Hawaiian plantation workers.

The origin of Spam musubi is disputed. Survivors of the Japanese American internment camps on the mainland of the United States claim to have invented the precursor to Spam musubi, when they placed seasoned slices of Spam on white rice in a baking pan. However, most origin stories focus on Spam's ubiquity in Hawaii during and in the aftermath of World War II. With few other options, the canned meat was incorporated into local cuisines wherever American troops were stationed. For example, South Korea's budae-jjigae, a stew of surplus U.S. military foods, included Spam. In the United Kingdom, where Spam was ubiquitous during the hardship of the post-War years, Spam acquired a stigma exemplified by the 1970 Monty Python sketch. Spam may not have been abandoned in the Pacific like it was in the U.K. simply because of the comparative economic deprivation experienced in the Pacific region.

The Honolulu Star-Bulletin said of Spam musubi in 2002 that "There is no definitive history for this aberration." Still, the newspaper relayed that a 2001 cookbook stated that the potential creator is Mitsuko Kaneshiro, who began selling them out of City Pharmacy on Pensacola Street in Honolulu and by the early 1980s was selling 500 handmade Spam musubi a day out of her own shop, Michan's Musubi. The other person said to be the creator of Spam musubi is Barbara Funamura of Kauai. Funamura sold Spam musubi out of the Joni-Hana restaurant in the Kukui Grove Center. The Garden Island in 1983 described it as, "Spam and rice, two local favorites, are combined in an enormous musubi (rice ball) wrapped in nori (sheets of dried seaweed)." Eventually Funamura's musubi was made using a box mold, taking on its familiar form.

In 1999, L&L Hawaiian Barbecue introduced the Hawaii regional snack as a menu item in its first mainland U.S. restaurant in Puente Hills, California.[8] As the Hawaii-based chain grew across several American states, so did the awareness and popularity of the snack, eventually becoming a mainstay on the menu, and making L&L the first restaurant chain to make the snack available nationally.

On August 8, 2021, L&L Hawaiian Barbecue established "National Spam Musubi Day" to celebrate the iconic snack from Hawaii. The holiday was officially recognized by Hawaii Governor David Y. Ige. with a public proclamation.

Spam musubi is the serving suggestion on tins of Teriyaki flavor Spam. Spam Musubi, generally together with egg and sometimes called Potama (for Pork+Tamago/Egg), is a staple of Okinawan cuisine. The nori is generally larger and wraps the entire sandwich.
