The Japan Mint's main campus occupies a large compound along the east bank of the Okawa River in central Osaka, and once a year — for one week in mid-April — it opens its central promenade to the public for the blossom viewing period known as Sakura-no-Tōrinuke ('passing through the cherry blossoms'). The tradition dates to 1883, when the director invited local residents to view the trees.
The promenade is lined with 300-plus cherry trees across 130 varieties, including numerous rare cultivars not found elsewhere in Osaka. Because the Mint's trees tend to bloom slightly later than those in the city's parks, this is often the last chance of the season to see full-canopy blossoms. The walk through the promenade takes about 15 minutes; visitors move in one direction only. Entry is free. Outside blossom season, the Mint has a small museum displaying historical Japanese coins.
