Kairaku-en (偕楽園) — one of Japan’s Three Great Gardens alongside Kenroku-en (Kanazawa) and Korakuen (Okayama) — was built in 1842 by Lord Tokugawa Nariaki specifically for sharing with the people (its name means “garden to enjoy together”). 3,000 plum trees in 100 varieties bloom in sequence from late February through late March, with early, middle, and late varieties extending the season to five weeks. During the Mito Plum Festival (水戸の梅まつり), selected evening illuminations combine plum blossom scent, lantern light, and night air in one of Japan’s most refined seasonal experiences.

The Kobuntei pavilion (original 1842 retreat of Lord Nariaki) provides elevated garden views. Lake Senba (2.7km walking path) adjoins the garden — lined with cherry trees that extend the seasonal display into April. The Mito Tokugawa Museum holds an outstanding collection of Tokugawa family swords, armor, and documents.
