Lotte will be developing the paid seating area within Inage Seaside Park Pool, a representative leisure facility in Chiba City, as the "The Marines Deck." The popular paid seating area within the pool, "INAPOO Seats," will be transformed into the "The Marines Deck," featuring player visuals and event logos from "BLACK SUMMER WEEK 2026," a special summer event held annually by the team.

In addition, there are plans to distribute 500 yen discount coupons for regular season games exclusively for The Marines Deck users, as well as special events featuring the team's performers.

The Marines Deck will be set up in the designated seating area of Inage Seaside Park Pool from August 11th to September 23rd. It is a paid seating area with 100 seats equipped with parasols, tables, and benches, and can be comfortably used by families and groups of 4 to 6 people. The usage fee is 3,000 yen on weekdays and 4,000 yen on weekends and holidays, and tickets will be sold on the Inage Seaside Park Pool ticket purchase website.

By accessing the QR code on the stickers placed on each table in The Marines Deck, you can obtain a limited-time coupon code for 500 yen off The Marines regular season games. The offer is valid for home regular season held at ZOZO Marine Stadium from August 11th to September 23rd, and sales will end once the planned number of tickets for each game and seat type have been reached.

Furthermore, a special event featuring the team's performers is planned for early August. Details will be announced on the team's official website and the Inage Seaside Park Pool official website as soon as they are finalized.
