As of right now, the Fujifilm Japan website lists the following B&W films as current products:

Neopan 100 Acros: 35mm/36 exp, 120, 4x5, 8x10, 4x5QL
Neopan 400: 35mm/24 exp, 35mm/36 exp
Neopan SS: 35mm/24 exp, 35mm/36 exp

Usually when a product is being discontinued, the listing will have a "product is being discontinued, limited to stocks on hand" tag on it. At the time I'm posting this, none of the products listed above has such a tag. So while there are no guarantees, it's likely that these products are indeed still in production.
