Hirosaki Castle Botanical Garden spreads across 23 zones inside Hirosaki Park's Sannomaru with about 1500 plant species and 124000 trees and herbaceous plants. Official pages for Reiwa 8 list the open season from 2026-04-10 through 2026-11-23, daily hours from 9:00 to 17:00 with ticket sales until 16:30, and no closed days during the season. Park fee guidance from 2025-04-01 sets individual day admission at 320 yen for adults and 100 yen for children (groups of 10 or more: 250 / 80 yen). The keepers' interior in the paid castle zone remains closed for several years; confirm combination tickets and cherry-festival hours before travel.
