Nippon-Ham announced on the 13th that they will wear the "ES CON FIELD Uniform 2026" for the opening three-game series against Softbank Hawks at Mizuho PayPay Dome starting March 27th.

It is unusual for a team to wear a special uniform for the opening game on enemy territory. The team explained, "We will take our first steps of the season wearing a uniform that symbolizes ES CON FIELD. We will take on The Hawks game in Fukuoka with the sense of unity and pride that we have built together with our fans. We decided to wear it for the season opener as a symbol of that determination."

The design, inspired by the natural grass of Escon, is a novel design with a black base and green lines. Manami commented, "I think it's a really new design with the grass incorporated into the design, and I love the colors too, it's cool." Tamiya added, "The pattern of soil and grass is stylish," and the players also gave positive feedback.

Additionally, public viewing events will be held at Ace Combat during the three-game series.
