Zen-noh is the name for the National Federation of Agricultural Cooperative Associations in Japan, a group of more 1,000 co-ops. Zen-noh was formed in 1972 with the joining of the Zenkoren and Zenhanren groups, both which had been established in 1948. Some importers have been putting Zen-noh decals onto gray-market Kubtoa and Yanmar tractors in an attempt to avoid trademark issues when imported these tractors into the United States.
