Bonkei (literally “tray landscape”) refers to the age-old Japanese tradition of arranging small greenery like rocks and moss to create a landscape. Chiaki Murata and his lifestyle product brand Metaphys has put a modern twist on the art, creating a series of planters to help spruce up your desk. The homes can be used alone, or you can combine multiple buildings to create a small town of green rooftops.
