Japanese trellises are made in the same style but they have some addition of woods at top in different designs and styles. They make the trellises by erecting some posts in the ground then make the top extending the ends of woods outside the beam in cone or sharp edges. Over these trellises, you can grow plant and let them creep over the Japanese trellises. Some people like to make trellises with two wooden posts on both side and fill the gap with tiny branches of wood making squares in between them. At the top make beams over it and on the edges, extend the woods in different style. You can make long queue of many posts and put the beams over them, when you fill the gap between the woods at the top, then you have enough space to grow different species of plants there and let them spread over the Japanese trellises.
