DD4D Brewing, operated by JAPANDEMIC COMPANY, will release three collaboration beers and original goods to coincide with AZURLANE MUSI9:FES. on September 5 and 6, 2026. Founded in 2019 and based in Matsuyama, Ehime, DD4D is a craft brewery that has been working with Azur Lane since 2023. This marks the fourth collaboration between the two.

The lineup

- `Sakura Islands (Owari)`
- Wood-Aged Rice Lager / 5.0% / IBU 25
- Brewed with rice alongside malt, this beer leans into a Japanese-inspired profile. It combines a clean finish with citrus- and herb-like hop aroma, a hint of smoky oak from sakura wood, and a soft sweetness from the rice.

- `Royal Navy (Scylla)`
- West Coast IPA / 6.5% / IBU 35
- Built around Nelson Sauvin, this IPA uses hops generously. The aroma brings white wine and berry notes, followed by passion fruit, lime, and grapefruit flavors, with a firm bitterness underneath.

- `Kingdom of Tulipa (De Zeven Provinciën)`
- Pilsner / 5.0% / IBU 20
- A crisp pilsner featuring Aramis and Lubelski hops. Floral and spicy aromatics lead into a clean drink, with biscuit and honey-like malt notes lingering on the finish.

All three beers come in 350ml cans and are priced at 1,000 yen each, including tax. Sales begin on September 5, 2026. At the event venue, Sankaku Hiroba in Shinjuku Sumitomo Building, DD4D will also offer draft beer, canned beer, gelato, and collaboration goods such as T-shirts, acrylic keychains, and glasses.

There are also purchase bonuses. Draft beer buyers receive a collaboration sticker, while customers who buy all three canned beers in a set of six total cans receive three character stickers. Both offers are limited in quantity and available while supplies last.
