Blue Box Season 2 premieres on Netflix on October 4, 2026, with new episodes every week. Netflix has confirmed the date and the weekly plan. In Japan, the anime also begins airing on TBS that Sunday. Fans who have been waiting for Taiki and Chinatsu will not get the whole season in one drop.
Where can you watch Season 2?
Netflix is the confirmed streaming home for the October 4 premiere. The exact hour a new episode appears can vary by country, so use the episode list in your local Netflix app for timing. The Japanese broadcast starts on TBS at 4:30 p.m. JST. This is a future premiere: Season 2 is not streaming yet on September 28.
The anime mixes sports and teen romance, so viewers can expect more gym practices alongside the relationships. Season 1 is already on Netflix if you want to catch up before the new episodes.
What is the story about?
Taiki Inomata plays badminton and has a crush on Chinatsu Kano, a basketball player at his school. When Chinatsu moves into Taiki's family home, they see each other outside practice as well as at school. The first season follows Taiki's feelings, Chinatsu's own goals and the friendships around them.
Season 2 continues that story. The new trailer also introduces Yumeka Kido, a former basketball teammate of Chinatsu's. She matters because Chinatsu's life does not revolve only around Taiki: her friendships and her ambitions on the court are still a big part of the show. You can catch up on Season 1 before October 4 if you have not watched it yet.
Who is making the new season?
Blue Box adapts Kouji Miura's manga. Daisuke Sakou directs Season 2, and Electric Circus handles animation. Shoya Chiba voices Taiki and Reina Ueda voices Chinatsu in Japanese. Netflix's season page also lists Akari Kito among the cast. You do not need to read the manga to follow the anime; the new season picks up the characters' ongoing story.
The important release detail is the weekly schedule. October 4 is the start, not the day all the episodes arrive. Netflix has not announced a complete episode-by-episode calendar on the page we checked, so the in-app list will be the best place to see each week's release time.
