Ninja Warrior
Kompetisi > Tantangan (Reguler) > Babak Kedua

Prinsipnya sama seperti babak pertama, akan tetapi tantangan pada babak kedua dibuat lebih sulit lagi. Mulanya, tidak ada tombol pengakhir waktu sehingga setelah menyelesaikan tantangan terakhir, gerbang terbuka dan peserta dinyatakan lolos. Mulai dari NW 8, peserta harus menekan tombol pengakhir waktu sebelum keluar dari gerbang. Jika peserta langsung menerobos gerbang tanpa menekan tombol, peserta dinyatakan gagal. Juri juga dapat menahan gerbang apabila peserta melakukan kesalahan / kecurangan seperti apa yang dilakukan Yamada Katsumi pada saat dia berada di Spider Walk NW 12 (dia tidak melepas sarung tangan khusus Chain Reaction).
Satu satunya tantangan di Ninja Warrior yang boleh menyentuh air hanyalah Backstream, dimana peserta harus berenang melawan arus. Wall Lift adalah tantangan yang sering dimasukkan dalam babak kedua. Pada awalnya, peserta akan mulai dari bawah dahulu. Mulai dari NW ketujuh, peserta akan memulai dari atas.
Pada NW keempat, terdapat 11 peserta yang lolos masuk babak ketiga. Akan tetapi, pada NW kelima, terdapat 3 peserta yang lolos. Pada NW kesembilan-belas, tidak ada yang lolos masuk ke babak ketiga karena kedua peserta gagal di Salmon Ladder (akhir kompetisi Sasuke yang tercepat). Hanya terdapat satu wanita yang lolos di babak kedua (NW ke 34).

Catatan:
Di NW 1 - 4 TBS, Spider Walk dipecah menjadi 3 yaitu Spider Walk, Moving Walls, dan Spider Climb sedang di G4TV tidak (dijadikan tantangan satu padu). Di NW 5 dan 6, Moving Walls juga ada, tetapi menjadi tantangan satu padu baik di TBS dan G4TV. Mulai dari NW 30, Spider Drop disatu-padukan ke tantangan Spider Walk.
Pada NW 8, belt yang menggerakkan tantangan Conveyor Belt dimatikan untuk menghindari sengatan listrik pada saat hujan deras. Tantangan lain juga terkena imbas masalah pada saat itu.
Pada NW 37, tantangan Rolling Log dilewatkan (langsung ke Salmon Ladder) dikarenakan cuaca yang tidak memungkinkan, menyebabkan kayu pelukannya bisa tersangkut dan susah dilewati. Juri memutuskan pula untuk mempercepat batas waktu menjadi 100 detik.
Di TBS, Salmon Ladder di NW 31 sampai 35 dipecah menjadi dua yaitu Salmon Ladder Nobori (naik) dan Salmon Ladder Kudari (turun). Bukan tantangan satu padu.
Di TBS, Brick Climb tidak dihitung sebagai sebuah tantangan.
Beberapa waktu khusus untuk peserta wanita:
NW 34: 120 s
NW 37: 110 s (juga untuk peserta di atas 50)
NW 40: 115 s (juga untuk peserta di atas 50)
NW 42: 110 s
