22 [tu:tu]

22 (tu:tu:, or two-two) is a wonderfully simplistic hybrid tube amplifier from Japanese designer Koichi Futatsumata, founder of Case-Real. Released by Japanese company Elekit, the 22 is made from aluminium with minimal controls and ports, just two control dials for volume and tone, a single pair of RCA jacks for input and four binder-posts for connecting speakers. The two valves that are nestled on top provide a warm, full sound.

Futatsumata has carried out numerous design activities with a main focus on spatial design. His work also included furniture and product design as well as architecture and landscape.

Born in Kagoshima, Japan, he started Case-Real in 2000 after graduating from the Department of Engineering and Architecture at Kyushu Industrial University. Case-Real provides design solutions for space, architecture and furniture. In 2013 Futatsumata set up Koichi Futatsumata Studio which is a development into product design. His architectural works include Aesop’s Stellar Place shop in Sapporo and a renovation of an abandoned house which acts as a dorm for nearby restaurant Il Vento (pictured).
