Mediumship

People who can see spirits are called mediums. Mediums are very rare, about 1 in 50,000 humans. A human can become one by being exposed to large amounts of spirit energy leaked by a spiritual being. Ichigo Kurosaki caused the people who were around him regularly to become mediums from the spirit energy he gave off. Some prominent mediums shown are Don Kanonji, and Karin Kurosaki.
