Then Summer Came(2008)

Overview:

A humorous wedding story fueled by a rather no-good father and son, disguised as the old and new “good guys.” The father Nobuo, and his son Tamio, are unable to mature, unable to break the parent-child roles, have no sense of responsibility, and keep holding on to the past. The pair is overwhelmed by all the colorful characters around them telling them what to do. They go to strenuous and humorous efforts to make Tamio’s wedding an event to remember.
