As a condition of marriage Sun's father requires that Jim work for him in his "business." We later learn that this involves much more than just paperwork. Having obtained permission to marry, Jin formally proposes to Sun on a bridge outside her father's stately home seen in this picture.
This scene was filmed at the Byodo-In Temple which is located in the Valley of the Temples off of the Kahekili Highway (83) in Kane'ohe. This is actually a bypass road that allows you to travel north to the shoreline of East Oahu. If you take the Likelike Highway from Honolulu watch for signs for the Kahekili Highway (83) north.
