・Stamp 1: 東海道どまん中 "Dead center of the Tōkaidō." The Tōkaidō, or eastern (東) sea (海) road (道), was a key travel route during the Edo period that served to connect Tokyo and Kyoto. It had 53 "stations" where towns and lodging were typically located. In terms of total distance, Fukuroi is situated at the halfway point.
・Stamp 2: Just the name of the post office.
Stamps 3-6: Name of the post office with an illustration of どんまんニャか, a mascot for the
Fukuroi Chamber of Commerce. ニャー (nyaa) is a cat's meow, so it's a play on どまんなか, referencing Fukuroi's location on the Tōkaidō.
・Below is a picture of various vegetables, tea and handmade goods on sale inside the post office.
