view-mode has code for the k and j bindings, but commented out:

(defvar view-mode-map
  (let ((map (make-sparse-keymap)))
    ...
    (define-key map "q" 'View-quit)
    ...
    ;; (define-key map "k" 'View-scroll-line-backward)
    (define-key map "y" 'View-scroll-line-backward)
    ;; (define-key map "j" 'View-scroll-line-forward)
    ...
    (define-key map "o" 'View-scroll-to-buffer-end)
    ...
    (define-key map "?" 'describe-mode) ; Maybe do as less instead? See above.
    (define-key map "h" 'describe-mode)
