I second Ashi Girl. The subs are not completed yet, though.
And just to add to what has been said, taiga dramas are usually pretty light on romance and comedy, although some are admittedly funnier than others (like Sanadamaru and Shinsengumi, both written by Mitani Koki), so proceed with caution.
Tempest, set in Ryukyu Kingdom (Okinawa) just before Japan annexed them, had a pretty strong romance as far as I can remember, but it's quite serious and not a comedy.
