We have intended to popularize geological maps, which are restricted professional uses presently. Two geologists, a map designer, and a print coordinator worked together to publish two maps at Asama Volcano and five maps in Izu Peninsula. They are easy to read for everyone because topographic relief is used as a base map. Every map was finished beautiful enough you want to exhibit it on the walls. We sell those maps not only at local shops but through the Internet for 500 yen, a surprisingly lower price than existing geological maps.
