Tomobe (友部町, Tomobe-machi) was a town located in Nishiibaraki District, Ibaraki Prefecture, Japan.
As of 2003, the town had an estimated population of 35,657 and a density of 607.34 persons per km². The total area was 58.71 km².
On March 19, 2006, Tomobe, along with the town of Iwama (also from Nishiibaraki District), was merged into the expanded city of Kasama.[1] The former Tomobe Town Hall is now converted into the new Kasama City Hall because prior to the merger, Tomobe had more people than the old city of Kasama.
