The Uda school is said to have originated in Yamato province.
The founder Kunimitsu moved to Ecchu province at the end of the Kamakura period. His son was UDA KUNIMUNE. The following is the lineage for these smiths:


He is the younger brother of Kunifusa, and is called Saemonnoj.  As for his being reputed to have been of the oan era, the era was probably moved back.  His works are few. 

KUN 652 (Rated at 75 points)

Uda school originated in Yamato province and was founded by Kunimitsu.  His son Kunifusa learned under Norishige that produced a different style of jitetsu by mixing hard and soft iron.  This is called matsukawa-hada or norishige-hada.  The hada on these swords is generally course in areas and is typical of the Uda school.


This is an exquisite sword .  Many of the swords from this time period were cut down and lost there signatures as this one but still retains all the characteristics of this smith and school.  You will see some coarse hada in places as is common from this school and is an important point to note for this school.

The hada on this blade is excellent and very rich looking.  It has a dark look and is very tightly forged in many places.  The hamon is also beautiful with many hataraki beautifully visible in hand.  It is also a very healthy hamon considering the age of this sword.  The shape of this sword is very elegant and it has a fine sweeping sori.  The boshi is also very healthy.  Overall this is a very fine and unique early sword retaining its original appearance.  This is why this sword received highly rated Toku-betsu papers.

A beautiful koshirae with lacquered saya that is finished in red. The tsuba is an interesting sukashi style and the balance of the furniture appears to be of a wave pattern and 16 petal chrysanthemom menuki. There is brown leather ito and brown sageo to match. All in all a very attractive set of mounts for a beautiful sword in the Uda tradition.

Etchū no Kuni Uda Kunimune

Ō-suriage mumei kuromi aru hada-ai ni Yamato kishitsu o shimesu suguha o yaki bōshi ga ichimai ni chikaki fukai-jō to naru kedo Muromachi no dōkō to kangamisubeki datō nari.

Tanzan shirusu + kaō


Uda Kunimune from Etchū Province

[The blade is] ō-suriage mumei but the forging structure with tendency towards a blackish appearance shows characteristic features of the Yamato tradition and with the hardening in suguha and the bōshi which almost appears as ichimai, the blade can be attributed to a Uda Kunimune smith of the Muromachi period.
