Depends on how you define "product."

The oldest continuous business is the Houshi Onsen in Komatsu, Japan. Houshi Onsen is a hot spring spa opened in 718 and has remained family operated since. Their product--reguvenation.

The oldest continuous manufacturer in the world is also in Japan. The honor goes to Genda Shigyo, a paper bag maker that has been in operation since 771.
