About Ibaraki
Ibaraki Prefecture extends along the Pacific coast northeast of Tokyo, combining ancient shrine culture, traditional gardens, and modern technology in an accessible package. The prefecture is often underestimated by travelers who pass through en route to northern Japan, but those who pause discover a rich tapestry of history, nature, and authentic local life away from the tourist crowds.
The prefecture is home to JAXA's Tsukuba Space Center and the renowned University of Tsukuba, making it one of Japan's leading science and research hubs. Tsukuba Science City, purpose-built in the 1960s, hosts over 150 research institutions and has shaped Japan's space program. Visitors can tour the Space Center's exhibits and marvel at rockets, space capsules, and astronaut training facilities.
Ibaraki's coastline stretches for 190 kilometers along the Pacific Ocean, featuring dramatic rocky cliffs at Isohamakaigan, the ancient port of Oarai with its famous torii gate rising from the waves, and excellent surf beaches. The prefecture is Japan's largest producer of natto (fermented soybeans) — a polarizing but protein-rich delicacy that features in the local cuisine. The annual Ibaraki Natto Festival celebrates this pungent staple with enthusiasm.
Featured Spot: Kairakuen Garden
Kairakuen Garden in Mito ranks among Japan's three most celebrated landscape gardens, alongside Kenrokuen in Kanazawa and Korakuen in Okayama. Established in 1842 by Lord Tokugawa Nariaki, it was designed to be enjoyed by the public rather than kept as a private retreat — unusual for its era. The garden is particularly famous for its 3,000 plum trees spanning over 100 varieties, which bloom from mid-February through March in a spectacular early spring display that draws hundreds of thousands of visitors.

Best Seasons to Visit
Spring (February–April) is the unmissable season, when Kairakuen's plum blossoms and later cherry blossoms transform the gardens. Autumn (October–November) brings colorful foliage to the mountains and pleasant temperatures for exploring coastal areas. Summer is popular for beach activities along the Pacific coast. Winter is mild compared to northern Japan, making Ibaraki accessible year-round.
