It's a Bake Off first - Japanese Week.
For the signature challenge the bakers tackle a Japanese version of an Asian staple, steamed buns. There's a tricky, layered technical and a showstopper inspired by kawaii - the Japanese love of all things cute and adorable. Who will be named star baker, and who will leave the tent for good?
The Great British Bake Off continues Tuesday at 8pm on Channel 4.
