Chiba Lotte Marines will develop 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 "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, a 500 yen discount coupon for home regular season game tickets will be distributed exclusively to The Marines Deck users, and special events featuring team performers are also planned.

The Marines Deck will be set up in the designated seating area of Inage Seaside Park Pool from July 11th to September 23rd. It is a paid seating area with 100 seats equipped with parasols, tables, and benches, where families and friends of 4 to 6 people can relax comfortably. 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 regular season tickets.

The coupons are valid for home regular season held at Zozo Marine Stadium from July 11th to September 23rd. Sales will end once the planned number of tickets for each game and seat type has been reached. In addition, a special event featuring team performers is planned for early August (dates and content are subject to change). Details will be announced on the team's official website and the Inage Seaside Park Pool official website as soon as they are decided.
