Kōshin-an
is a retreat including a Japanese garden and a house in Matsuyama, Ehime. This was once a villa or a humble cottage of Kurita Chodō, a haiku poet of the Edo period. Today, part of the house was restored to preserve its original form as one of the special historic sites in Ehime, and NPO corporation GCM Kōshin-an Club are involved in voluntary activities to promote it.
