seiza is a Japanese singer-songwriter from Japan. Publicly verified information about the artist’s early career remains limited, but the available record identifies Seiza as a solo act and provides a clear recent anime credit. In April 2025, Seiza released the music video for the ending song of The Beginning After the End, bringing the artist into the anime music conversation.
That association makes Seiza relevant for listeners searching for Japanese artists connected to anime ending songs, while keeping the biography grounded in confirmed facts only. Seiza also maintains an official website at seiza-official.jp, which serves as a direct reference point for the artist’s work. For readers who want an anime music entry point, that 2025 release is the clearest confirmed milestone available so far.
