On the 3rd, Lotte announced that they will be developing the paid seating area within Inage Seaside Park Pool, a representative leisure facility in Chiba City, into the "The Marines Deck."

The popular paid seating area "INAPOO Seats" within the pool will be transformed into the "The Marines Deck," featuring player visuals and event logos from the team's annual summer special event, "BLACK SUMMER WEEK 2026."

In addition, there are plans to distribute 500 yen discount coupons for home games exclusively for The Marines Deck users, as well as special events featuring team performers. The Marines Deck will be set up in the designated seating area of regular season Park Pool from July 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 are sold on the Inage Seaside Park Pool ticket purchase website. By accessing the QR code on the sticker attached to each table in The Marines Deck, you can obtain a limited coupon code for 500 yen off The Marines home regular season tickets. The offer is valid for home regular season held at Zozo Marine Stadium from July 11 to September 23, and sales will end once the planned number of tickets for each game and seat type has been reached.

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