famous Murakami Torajiro. made Japanese antique bronze boat okimono or ornament. He was an artist during the Edo and early Meiji period, and all we know of his history is that he died in 1900. We are not positive but most likely it was made by the slip cast method. Tools are then used to make the designs on the boat. The color is different on the outside from the inside so the outside was colored somehow, perhaps lacquered. A dragon over waves is carved on each side. A stitch pattern is made to represent each wooden plank. In one discussion on Catawiki the possibility that the marks were made with silver was mentioned, and they are with a lighter color, and the work on that piece was very similar to this and said to be from the Meiji period.. In the center of the lines on the upper part of the boat is attached to show where the oars would go, it is very detailed.
Both I and the seller Takashi san in Japan looked for information about the artist- . Just a few sites where he is mentioned were found, it is very hard to find anything about Edo artists on the internet so we do not have any history, there is probably some more found in books. Takashi found a site on artist marks in Japan and they had taken the mark from a book on marks by Bowes, James Lord, I could not find this book. The mark on the bottom of the boat same as the one found in the book, is 大日本明治年製村上虎治郎造, or 'Dai Nip-pon, Mei-ji nen sei, Mura-kami Tora-ji-ro tsukuru '. That means 'made in great Japan during the Meiji era, by Murakami Torajiro, of a crane or tsukuru'. I have not yet asked for help in determing if this mark reads the Edo or Meiji period of 1868-1912, as the artist worked during the Edo period as well.
This is a very fine and tasteful metal art piece by famous Murakami Torajiro of old Japan. Although the information below discussed copper, I believe the methods are similar.

the Copper Lost Wax Cast Method
Techniques of the main cast Casting a metal which is melted and poured into a prototype which had been made beforehand, it is metalworking method for the form of interest. Although the basic technology of casting was born thousands of years ago has not changed even now, and if there is a variation of a number, you cannot use the four main techniques in Takaoka copperware. By the respective techniques, also different prototype development
Wax casting method This is the most high-precision technique. Beeswax to create a prototype in which the combined boiled pine resin extracted from the hive and Japan wax extracted from the fruit of goby and baked at high temperature wrapped in soil, a prototype of the wax is melted by the heat, the gap is born . And pouring the metal to be dissolved here.
Lost Wax Method A molten metal is poured into a mold that has been created by means of a wax model. Once the mold is made, the wax model is melted and drained away. A hollow core can be effected by the introduction of a heat-proof core that prevents the molten metal from totally filling the mold. The lost-wax method dates from the 3rd-millennium bc and has sustained few changes since then. To cast a clay model in bronze, a mold is made from the model, and the inside of this negative mold is brushed with melted wax to the desired thickness of the final bronze. After removal of the mold, the resultant wax shell is filled with a heat-resistant mixture. Wax tubes, which provide ducts for pouring bronze during casting and vents for the noxious gases produced in the process, are fitted to the outside of the wax shell, which may be modeled or adjusted by the artist. Metal pins are hammered through the shell into the core to secure it. Next, the prepared wax shell is completely covered in layers of heat-resistant plaster, and the whole is inverted and placed in an oven. During heating, the plaster dries and the wax runs out through the ducts created by the wax tubes. The plaster mold is then packed in sand, and molten bronze is poured through the ducts, filling the space left by the wax. When cool, the outer plaster and core are removed, and the bronze may receive finishing touches.
