        Japanese Fishing Line Size

        When it comes to fishing line, not all them are created equal

        Japanese fishing line size explained

        When it comes to Fishing Line, not all companies are created equal.

        More than 70+ companies manufacture fishing lines in Japan alone, not to mention other countries.

        VAIRVAS – Morris Company Ltd. is one of only 27 companies in Japan, however, that as a member of  JAFTMA (Japan Fishing Tackle Manufacturers Association) follows the strict industry guidelines and specifications agreed to create high-quality and reliable products.

        VARIVAS is committed to putting fair and accurate products into the hands of anglers. 

        JAFS Standard Size

        VARIVAS – Morris Company, like many Japanese fishing tackle manufacturers, has adapted the universal industrial standard called JAFS standard for Japanese fishing line size (diameter) to promote fair, transparent, and high-quality products for consumers.

        VARIVAS follows the rules when it comes to quality.

        The VARIVAS brand parent company Morris Co., Ltd. is one of 27 companies that have officially agreed to uphold rules and standards specified by the JAFS standard. The pride of our quality is essential to VARIVAS for building Angler’s trust.

         About 号 =Go/Goh/Gou 

        Should you trust the number on the package?

        In Japan, fishing line diameter, gauge/number, is referred to as “号” (pronounced and written in Latin/English script conversion as “Go/Goh/Gou”). However, “号” as a suffix, simply means “number,” along with other meanings in Japanese. It does not follow any universal conversion standard except in the case of terms agreed upon by the member of JAFTMA (Japan Fishing Tackle Manufacturers Association) and its specific JAFS size specification.

        If a manufacturer is not a member of JAFTMA they may or may not follow the rule specified. 

        With VARIVAS products, you can always trust the markings including the size, diameter of the line and weight capacity.

        We say what we mean.
