Nippon, Japan, Made in Japan and Foreign
Early Japanese export pottery was marked with, Nippon, the Anglicised Japanese name for Japan.
The legislation of the USA in 1922 concerning the marking of imported items with their country of origin can be used to assist in the dating of Japanese export pottery throughout the world. This results from the obvious conclusion that the majority of manufacturers in Japan would not have gone to the trouble of having different polices for marking export items. However, given the cost of marking items, many items exist without any marks. Many countries continued to be happy with paper labels. This may also be the result of accidental omission.
Similarly, the use of "Foreign" or FOREIGN" on items imported onto the UK can be used to place an item within certain dates.
Contrary to many articles I have read I have found there is little or no correlation between the colour of the base marks on Japanese pottery and the date of manufacture. This is evidenced by many items where the base mark occurs in various colours. Also see below about the registration of logos in Japan. It is possible that potters registered the various colours to stop others from using similar base marks and then had to use the various colours themselves to preserve the registration.
Potters, factories and importers/exporters
I have listed some of the Japanese potters that I have been able to identify when researching the juicers on my website. It must be noted that a significant problem has arisen when reliable sources attribute some base marks to different factories. Perhaps some sources are confusing potters/factories with importers/exporters who often used their own distinctive basemark.
Registration of maker's marks (logos)
The registration of maker's marks in Japan were so specific including colour etc that it allowed for other companies to pirate a mark by doing as little as changing the colour. I am not sugsesting that all the different colours were used by totally different makers.
I have created a page to allow easy comparison of the variety of base marks and base mark colours used on juicers of the same form (same mould). See: Juicers_Japanese_basemark_variants.html
The table below lists potters, factories and importers/exporters as indicated by researching a wide range of books and internet sources.
The following listings are a work in progress, however, sufficient to demonstrate the point that I am making.
|This mark is listed across the internet, and books, as Maruhon Ware and/or Marumon Ware and/or Maruhun Ware. I think this is a result of a smudged marks or partial marks. I have examples with smudged marks that would easily pass as Marumon Ware because the 'H' is distorted. I have seen partial marks that look like Maruhun Ware because the top of the 'O' is missing and it appears to be a 'U'.
Maruhon Ware has not been attributed to any factory and may be an exporter/importer brand. It is worth noting that some marks have the overlapping double 'V' for the 'W' as seen in Marutomo Ware. This could suggest that there was some form of relationship between the two brands.
This mark is listed across the internet as Maruto Mu Ware. I think this is a result of a labelling by a very distinguished authority on Japanese and Chinese pottery. He listed an item where the basemark appears to be "MARUTOMUWARE" and this has been relied upon by others. However I would suggest that his example has a partial mark with the top of the second 'O' missing and appearing to be a 'U'.
Marutomo Ware has not been attributed to any factory and may be an exporter/importer brand. It is worth noting that some marks have the overlapping double 'V' for the 'W' as seen in Maruhon Ware. This could suggest that there was some form of relationship between the two brands.
