The Blooming Season of Alpine Plants

Here’s an introduction to the alpine plants that can be seen on the trekking courses in Shiga Kogen. Most of the flowers listed here can also be seen at the Higashitateyama Alpine Plants Garden. The garden is open from mid-June to early November, and is accessible on days when the Higashitateyama Gondola is operating. (Free admission)

In the details for each flower below, you’ll find information on which trails they can be spotted along. Please note that this is for reference only — many flowers may also be found on other trails not listed, so we encourage you to take your time and enjoy discovering them as you walk.
