Hirosaki Castle Cherry Blossoms — Japan's Oldest Castle Town Sakura

Hirosaki in southwestern Aomori Prefecture has preserved both its castle and its cherry blossom culture with a devotion that sets it apart from anywhere else in Japan. The city's castle park contains over 2,600 cherry trees planted across 49 hectares, surrounding a beautifully preserved original castle keep that dates to 1611. The combination of authentic Edo-period architecture and centuries-old cherry trees creates what many sakura connoisseurs regard as Japan's finest blossom experience.

Highlights

Hirosaki Castle's three-story keep (tenshukaku) is among Japan's twelve remaining original castle structures — not a modern reconstruction but a genuine survivor of the feudal era. Surrounded by deep moats and massive stone walls, the castle gains a timeless quality that modern replica castles simply cannot match. In late April and early May, Somei Yoshino and weeping cherry trees frame the keep in clouds of pink blossom.

The festival's most photographed moment comes slightly after peak bloom, when fallen petals carpet the moat surface — the hanaikada or "flower raft" — turning the water pink. Viewing this from the bridges that cross the moat, with the castle reflected beyond, is an experience that justifies a trip across Japan.

The surrounding city retains samurai district architecture, historic temples, and the traditions of Tsugaru lacquerware and shamisen music, making Hirosaki one of the most culturally complete castle towns in Tohoku.

Getting There & Tips

Hirosaki is on the JR Ou Line, about 35 minutes from Aomori city. Walk or take a bus from Hirosaki Station to the castle park. Festival entry fee during blossom season. Evening illumination is offered nightly.

Best Time to Visit

Late April to early May for cherry blossoms. The Hirosaki Cherry Blossom Festival typically runs about two weeks. For the hanaikada effect, visit about one week after peak bloom begins.

Practical Information for Your Visit

• Best season and viewing period: According to official information, from mid-April to early May Hirosaki Park is filled with about 2,600 cherry trees of 52 varieties, including Somei-Yoshino and double-flowered yaezakura. Once the Somei-Yoshino have turned to leaf, the yaezakura and the Hirosaki Nanazakura (the seven cherries of Hirosaki) take the leading role. Flowering dates can shift greatly from year to year.
• Dates and illumination: In 2026 the Hirosaki Cherry Blossom Festival runs from Friday, April 10 to Tuesday, May 5 (the start was brought forward by 7 days in response to early blooming). The park is illuminated from sunset until 22:00, and the food stalls are open roughly 9:00 to 21:00.
• Admission: Entry to the Honmaru and Kita-no-Kuruwa of Hirosaki Castle costs 320 yen for adults and 100 yen for children for individuals, and 250 yen for adults and 80 yen for children for groups (10 or more paying visitors). The Hirosaki Castle Botanical Garden costs the same. A combination ticket valid for one day for the Honmaru and Kita-no-Kuruwa, the botanical garden and the Fujita Memorial Garden is 520 yen for adults and 160 yen for children. An annual pass is 1,040 yen for adults and 310 yen for children. From November 24 to March 31, entry to the Honmaru and Kita-no-Kuruwa is free of charge.
• Access: From Hirosaki Station on the JR Ou Main Line, reach Hirosaki Park by bus or on foot.
• Clothing and gear: The park is extensive and involves a good deal of walking from the outer moat to the Honmaru, so wear comfortable shoes. Mornings and evenings in Hirosaki are chilly in April and May, so bring a jacket.

* The paid areas are open 9:00 to 17:00 from April 1 to November 23, and 9:00 to 21:00 during the Hirosaki Cherry Blossom Festival. However, if the Somei-Yoshino bloom early, the hours may revert to the usual 9:00 to 17:00 even during the festival. The Hirosaki Castle Botanical Garden is open from mid-April to November 23, 9:00 to 17:00 (tickets sold until 16:30). * Because of the stone wall repair project, the castle keep of Hirosaki Castle has been moved to a temporary keep base inside the Honmaru, and viewing of the interior has been suspended since November 23, 2025. From July 2026 the work of pulling the keep back to its original base begins, and it is expected to be completed around mid-November of the same year. As the keep will be moved back without a temporary roof or other covering, its exterior can still be seen and the work itself can be viewed from an observation deck. Seismic reinforcement and conservation work will continue even after the keep is moved back, and viewing of the interior is scheduled to resume once the work is completed in fiscal 2032. * Hirosaki Park has been selected as one of Japan's Top 100 Cherry Blossom Spots and one of Japan's Top 100 Urban Parks. The keep, the Tatsumi Yagura, Ushitora Yagura and Hitsujisaru Yagura turrets, the San-no-Maru Otemon and San-no-Maru Higashimon gates, the Ni-no-Maru Minami Uchimon and Ni-no-Maru Higashi Uchimon gates and the Kikkomon gate of Kita-no-Kuruwa are nationally designated Important Cultural Properties, and the park itself is a national historic site. * For enquiries about the paid areas and fees, contact the Parks and Green Spaces Division of Hirosaki City Hall (0172-33-8739).
