JNDA 01-27. Minted in both the Taisho and Showa eras. The 10 sen has the same design as the contemporary 5 sen. The center hole of the obverse is surrounded by the 'Sacred Mirror' emblem, which is one of the Imperial treasures. The phrase 'Dai Nippon' or 'Great Japan' is above the hole, and under the hole is the date, and these are superimposed on a wave-like background. The reverse shows the Chrysanthemum crest (the Imperial Seal) above the hole with the denomination below. Underneath is foliage of the paulownia (the Paulownia represents the government).
The coin was minted from T9 (1920) - S7 (1932) non-continuously.
Diameter 22.17, cupronickel, weight 3.75 grams.
