What Medication is Allowed Bring?

Hi All,

I was curious on if any of the medicines below were okay to bring to Japan when I travel there:

Benadryl (diphenhydramine)

Allergy Relief (cetirizine hydrochloride)

Eye Itch drops (ketotifen fumarate ophthalmic)

Advil (ibuprofen)

Clobetasol

Also, are there other medicines you guys recommended I should pack for Japan as well?
