Sōkan T-Shirt, white-blue
Sōkan T-Shirt, white-blue
Premium martial arts t-shirt from the Duality Collection featuring artwork inspired by Katsushika Hokusai's legendary sketches and the concept of Sōkan (双観)—the ability to hold two perspectives simultaneously. A unique piece for karate, BJJ, MMA, and martial arts practitioners who appreciate Japanese art and philosophy.
In a world obsessed with choosing sides, true strength comes from understanding that opposing forces coexist within us. Power and restraint. Tradition and innovation. Conflict and peace. The yin and yang is not about opposing forces but complementary aspects of a unified whole that moves constantly.
The design draws from Hokusai's "Hokusai Manga" collection. Sketches depicting warriors, demons and everyday life. The blue is inspired by the indigo dyed samurai under-armor, representing loyalty and fidelity. The white by Shinto tradition, symbolizing purity and spiritual enlightenment.

FAQ's
What does Sōkan mean?
Sōkan (双観) is a Japanese term meaning "dual perspective" or the ability to hold two viewpoints simultaneously. It represents the martial arts principle of opposing forces. Hard and soft, offense and defense exist together and create balance through their interaction.
What's included with the t-shirt?
Each Sōkan piece comes with an exclusive booklet exploring the concept of duality. The booklet provides deeper context for the Hokusai-inspired design and its connection to traditional martial arts principles like yin and yang, offering both philosophical insights and practical applications for practitioners.
How does the regular fit compare to the Kō Collection's oversize fit?
The Sōkan t-shirt features a regular fit (true to size) for everyday comfort, while the Kō Collection has an intentionally oversized 90s-inspired fit. If you prefer a roomier fit, consider sizing up.
What is SHISA?
The brand takes its name from Okinawan mythology. Okinawa, Japan -
the birthplace of Karate - is home to traditional guardian figures called shisa, protective beings that ward off evil spirits and bring good fortune.
