Welfare Kendama "Hare" - Red - Handbook Set This set includes a handbook with detailed explanations of the benefits of kendama, brain-awakening training methods, and descriptions of techniques for levels and the preliminary first dan. (Supervised by Dr. Takuji Shirasawa, MD & the Japan Kendama Association) "Welfare Kendama" was developed to help prevent dementia and aging by utilizing kendama, a full-body exercise that uses not only the hands but also the knees and hips. Compared to competitive kendama, the sizes of each cup are approximately 25% larger, and the edges of the cups are thinner and a part of the handle is shaved off to reduce weight, making it easier for the elderly to handle. ■ Large cup diameter: 5.3cm (※4.2cm for competitive use), Small cup diameter: 5.1cm (※3.8cm for competitive use) ■ Material: Both the ken and tama use domestically sourced beech wood. 　【Recommended by the Japan Kendama Association】※Grade and preliminary first dan exams are available Thank you for viewing! ☺️ Please feel free to comment if you have any questions.
