World Champion Toru Osugi Co-develops with Structural Architect: 'Slack Anchor' Enables Slacklining Without Trees, Strengthening Proposals for Summer Outdoor Season

Slackline Research (located in Soja City, Okayama Prefecture; Representative: Toru Osugi), a specialist brand for slacklines, is strengthening its proposals for 'tree-less' slacklining for the summer outdoor leisure season, centered on its self-developed anchor system, 'Slack Anchor.' It was developed by Toru Osugi, who in 2013 became the first Japanese person to win the Slackline World Cup. The product was designed in collaboration with a structural architect and is equipped with safety features based on strength calculations. Planning, design, and development are conducted in-house by Slackline Research in Okayama, Japan.

Background: The Biggest Barrier to Slackline Adoption

Slacklining is traditionally done by attaching a line between two trees at the appropriate distance. However, in reality, many people cannot take the first step despite their interest due to reasons such as: 'There aren't two suitable trees at home or in the neighborhood,' 'I feel hesitant about wrapping it around trees in public parks,' or 'I want to try but can't find a place.' This has been the biggest bottleneck for slackline adoption.

'Slack Anchor' is a product that directly solves this bottleneck. The cylindrical anchor structure, fixed by driving special steel stakes into the ground, makes it possible to set up a slackline without trees. Whether it's your backyard, a grassy park, a beach, a campsite, or a riverbed, you can choose any location as long as there is solid ground. Since it does not use trees, it does not damage tree bark, and it has the added benefit of making it easier to obtain installation permits from park administrators.

This feature also lowers the barrier to entry for commercial facilities, parks, companies, and local governments that have previously declined slackline experience programs because they lacked suitable trees on their premises. It is actually being used in the company's traveling events and workshops.
