Saitama Seibu Lions will hold a series of denim fashion-themed "Omokashi Series" for six matches against Tohoku Rakuten Eagles from Friday, May 8 to 10th and against Orix Buffaloes from 22nd to 24th.

The event is a collaboration with the Japan Jeans Association, which hosts the Best Jeanist show. Blue denim, which is also the blue color of The Lions team, connects players and fans and creates a sense of unity throughout the stadium. During the event, fans wearing denim items will be given original stickers to enjoy their denim coordination.

One of the highlights of the event was the start of a fan vote to choose The Lions's "Best Jeanist" from among 13 players dressed in blue denim. In addition to voting via Saitama Seibu Lions's official LINE, there will also be a polling station in Belluna Dome during the dress-up series in May, where you can enjoy a photo spot where you can take photos with panels of athletes wearing denim. The best jeanist will be announced before the game on the 24th.

On the 9th (Sat.), “CITEN ×LIONS Metallic Bag ” will be distributed to all visitors in collaboration with“ CITEN ”, a brand by select shop “United Arrows ” that is popular among young people. On the 23rd (Sat), “Tokyo Girls Collection × LIONS Collaboration Tumblers ” will be distributed in collaboration with the largest fashion festival in history.

During the event, the “CITE × Manaya Nishikawa Metallic Bag, ” which was produced with Manaya Nishikawa's participation in selecting the fabric, can be purchased as an option for the game on the 8th, 10th, 22nd and 24th. In addition, the company has also started to sell to order exclusive “Omekashi Series ” goods featuring photos taken by players.

In addition, The Lions fan Raimu Okamiya will be on the 10th (Sun.) and five-member boy group WILD BLUE will be on the 24th (Sun.). Tickets for the game will be sold from the fan club's first bank lottery on Friday, March 6, with general sales starting on Monday, March 16.
