Sunline Co., Ltd. is a fishing company that has been around since August 1977. Established in Yamaguchi Prefecture, the company was known for their water resistant resin hardening technology and their lures were released in the US under the name Dairiki back in 1987.
The “Dairiki” name would transition to Sunline’s tuna longline fishing products as of 1989 and by 1991, the company was one of the top producers of nylon fishing lines. And in 1993, they would release their fluorocarbon leader line “Tornado” and in 1994, their fluorocarbon bass fishing line “FC Sniper”.
By 2000, Sunline would release their pink fluorocarbon leader titled “Tornado SV-I”, a line that made it difficult for fish to see.
And by 2008, the company would established their wholly owned subsidiary “Sunline America, Co., Ltd.” in Los Angeles.
In 2023, the company has now ventured into new plasma technology with “Plastas” and entered the nail care industry. Their plasma technology was also used for their MACHINGUN CAST.
And with the diversification, Sunline became a company that incorporates manufacturing, processing, and sales of fishing lines for leisure, fisheries, and commercial use. Manufacturing, processing, and sales of monofilaments for industrial materials. Procurement and sales of various fishing tackle. Surface modification processing and equipment sales utilizing atmospheric pressure plasma technology.
On YouTube, the company has one of the oldest presence on YouTube at over 18 years and has over 31,000 subscribers.

Summary: It’s been 25 years since the release of the original Machinegun Cast. For this fourth generation model, the goal was “the best casting feel and its sustainability.” This was achieved by incorporating Plasma Rise technology. The testers involved in the testing process said, “You’ll understand after just one cast,” and the improved casting feel and accuracy will surely bring a smile to your face. While retaining the performance that allows you to fully experience the appeal of nylon line, it inherits the versatility of fluorocarbon line. Strength and ease of use are fundamental. Beyond that, the Machinegun Cast continues to evolve, pursuing a feeling that, even if not visible in the numbers, makes anglers think, “I don’t want to use any other line.”
