Dai-ichi Life Hibiya First Workers' Gate Renewal

DN Tower 21" completed in 1995 was renamed "Dai-ichi Seimei Hibiya First" in 2022. The entire building was renovated based on the concept of "realizing wellbeing through connections and bonds. We sincerely hope that the renewal of the building (including a through passageway that stimulates and leads the five senses) and the interior design clad in the spirit of tradition will work on the consciousness and sensitivity of the office workers and satisfy them both physically and mentally.
