In 2015, I created my first planisphere compiling Ainu constellations. Since then, I have developed several versions, including improved editions and planispheres based on different concepts.
Since creating these planispheres, I have been sharing the joy of Ainu constellations through lectures and workshops using them.

The unique Ainu star names shown on this planisphere were collected over several decades starting in the late 1940s by the late Mr. Tomio Sueoka from Asahikawa. He visited Ainu communities across Hokkaido, recording the names he heard. The star names published in his books, "Ainu no Hoshi" and "Constellations and Traditions Seen by the Ainutari", were carefully cross-checked and included only when the same accounts were confirmed by multiple people. The number of such names exceeds 100. By compiling these data and mapping them into star charts, we can appreciate the humor and keen powers of observation of the Ainu people at the time, as well as learn about Hokkaido’s history, wildlife ecology, and even climate changes through the constellations.

This planisphere features about 50 star names, primarily those that, according to Mr. Sueoka’s surveys, were consistently mentioned by multiple Ainu people across different regions of Hokkaido. Many of these names are associated with important Kamuy (Gods) in Ainu tradition, while others reveal climate patterns and animal ecology through the movement of the stars, making them especially fascinating.

This planisphere can be obtained through limited distribution (with explanations at online events), lectures, and workshops.
