Smiths of this school lived in Ukai no Sho (鵜飼庄). This school is also known as Ukai (Ugai) and Kumo (as for KUMO or UN character - 雲 which is used in the names of some smiths).

See Yumei Koto Taikan (p.32) for genealogy on Unrui.

Workmanship and style [1]


The works of the smiths of this school are about the same from one smith to the next, therefore we give a general description here rather than for any one particular smith.

Shape and construction

Tachi style in both the Early and Mid Kamakura Period and in the ikubi kissaki tachi.
On the whole, the shape of the blade in general is made very firm with high shinogi and thick kasane.


Bo-hi and futasuji-hi are seen in rare cases.


The width of the yakiba is made wide and in nioi with the pattern in chu-suguba with ko-choji midare and ko-midare mixed together, which will be made in saka style.

Differences between Unshō and Unji

TBJ-508, p.16 wrote:

Generally speaking, Unshō tempers narrow hamon with a few hataraki and Unji does wide hamon with many hataraki.
In addition, Unshō signs his signature above the mekugi-ana and near the mune line but Unji usually signs below the mekugi-ana and in the centre of the nakago.
