Seibu Lions will hold six games at Belluna Dome between March 31st and April 5th, calling them the "2026 Opening Series."

At the home opener against Orix Buffaloes on March 31st, they will be handing out bracelet-shaped lights that will light up in time with the performances inside Belluna Dome. Goods will also be available for distribution to attendees at the two weekend games.

The bracelet-shaped light, modeled after the team's mascot, Leo, changes color in nine different ways to match the stadium's lighting. It lights up when starting line-up is announced, during win ceremonies, and when Seibu Lions players hit home run, making it a fun item to use all year round to liven up the stadium.

This year's home games will feature new performances using laser lights and wirelessly controlled lights, as well as light-themed videos broadcast on the stadium's vision.

In addition, at the games Rakuten Eagles on April 4th and 5th, "initial logo vests" will be distributed on the 4th and "word mark hoodies" on the 5th.

The padded vest and fleece-lined hoodie are sure to be useful items at the stadium during the chilly period after the season starts.

Additionally, at the three games on April 2nd, 4th, and 5th, there will be special events for spring break, such as a "Kids' Big Raffle" where children can win balls autographed by players and other prizes, as well as up to 30 minutes of unlimited play time at the Teikyō Kids Field.

Tickets for the 2026 Opening Series and other games from March 31st to April 30th will go on sale starting with a fan club advance ticket lottery on February 13th. General sales will begin on February 23rd.

We want to liven up the start of the season at Belluna Dome with our enthusiastic cheers.

I would love for many The Lions fans to come and see us play at Belluna Dome, and I'm really looking forward to competing again this year with those huge cheers behind us.

This year's L-Vision filming was different than usual, flashy and amazing! I hope you'll look forward to it. The opening game of professional baseball is on the road, but six consecutive games at home are still special, so I look forward to seeing everyone there. Let's all win!
