Halal food, the only type Muslims are permitted to eat under Islamic law, is in hot demand, say managers at Halal Deli, which delivers boxed lunches to devout Muslims in Tokyo.

"Halal foods are currently delivered only within the 23 wards of Tokyo, but we want to expand the delivery area," a member of the deli's staff said.

The shop, based in Koto Ward, opened to meet growing demand for halal food from tourists from Indonesia and other Islamic countries.
