Ko-Tosho (swordsmith) Tsuba. Iron, marugata, slightly convex (goishi-gata), with image of cherry-blossom, snowflake, and hat in sukashi openwork. It is ubu without hitsu ana dating back to Muromachi period. The image depicted is one representing the Noh play “Hachi-no-ki”, which tells of the sacrifice of an innkeeper who cut down his treasured potted trees so that he could put them in the fire to provide warmth for a traveling monk. The monk was actually a lord in disguise, who eventually repaid the innkeeper’s kindness by granting him some lands. A very tasteful tsuba, exemplifying the wabi-sabi aesthetic of restrained elegance.

NOTE:
As I wish to make deals as honest and faithful as possible, I would like to add to above that Ko-Tosho / Tosho tsuba are not the area where I am most experienced and you should judge carefully from pictures and video and decide for yourself whether this tsuba being Ko-Tosho, Tosho or even a edo piece made in (Ko-) Tosho style.

I felt convinced about this one being Ko-Tosho when I compared to this one (among others): https://tsuba.info/product/ko-tosho-ume-2/

Iron, marugata, image of cherry blossoms on floating rafts (hana ikada). Bushū Itō school. The image is one which evokes the harvesting of wood from the forests around Kyoto, bundling the logs into rafts, and floating them down the Kamo River to be sold in Osaka. In the springtime, the cherry blossoms would fall onto the logs, and the site of the logs floating on the river, decorated with Kyoto’s cherry blossoms would delight people along the riverbank. Highlights in gold inlay. Two hitsu-ana (one plugged with shakudō). Mid Edo era.

Iron, mokkō-gata, with surface done in chirimen-amidayasuri style. Saotome school. A rather austere tsuba, with the radiating lines giving the appearance of light radiating from Amida Buddha, from which the rippling effect derives its name. Possibly Momoyama or earlier. One hitsu ana.

Shakudō, marugata, scattered shippō (jewel) pattern in sukashi openwork. Although the mei of Tadashige is legible, there are no records of a metalworker using this name in Wakayama’s index of metalworkers. The design is classically minimalistic, perhaps reflecting the taste of a swordsman student of zen.

Iron, marugata, mokume (wood-grain) pattern on the base, with symmetrical sukashi designs of Tachibana. The mokume iron base is distinctive, and hints at the Myōchin school, or perhaps one of the metalworkers from Sado Island (Sashū). The design looks to be a tachibana (citrus) flower, often used in family crests. Two hitsu ana formed by the openwork of the flowers. Mid Edo.

Note: Although its school is hard to pinpoint. I think Myochin is the right attribution. I can see that wood-grain with sukashi is also a hallmark of the smiths working on Sado Island (who themselves were probably influenced by Myochin).
