As a very insular society, Japan has developed a culture that can be very interesting and sometimes bizarre to the outside observer. For example, in recent years, many Japanese have become infatuated with moss. Nature excursions centered around observing the thousands of species of Japanese moss have exploded in popularity to the point that the demand for a place on these trips far exceeds availability.
Selling moss-related products like moss-containing jewelry has also become a lucrative market. You can buy rings that have tiny containers holding moss instead of stones. For many young women in Japan, love of these plants has become a part of their identity. These young enthusiasts call themselves “moss girls” and organize moss-themed events such as viewing parties, where they make drinks inspired from the plants.
