Incorporate antique obelisks with a weathered finish into your Japanese Zen garden for a unique twist. These obelisks, with their aged appearance, will add a sense of history and tranquility to your outdoor space. Surround them with minimalist landscaping, including gravel, rocks, and carefully pruned bonsai trees. The obelisks can be used to showcase a traditional Japanese lantern or a cascading water feature, creating a harmonious and serene atmosphere.
