Tachikawa Blind Co., Ltd. (Head Office: Minato-ku, Tokyo; Capital: 4.475 billion yen; President and CEO: Hisaya Ikezaki) will expand the light-adjusting vertical blind "Aire" with new specifications optimal for large opening windows, and will release it on August 3, 2026 (Mon). ■ Background In recent years, with the adoption of large opening windows in homes and the diversification of their shapes, the needs for window treatment products have been changing and diversifying.
