four seasons in Kuju

Spring is black

In March, Mansaku (Hanamelis japonica) begin blooming in Kuju mountains, and various early-spring wildflowers are blooming in the forests of deciduous broad-leaved trees. Grasslands in Kuju, however, turn black every spring. It is because the local people burn the dead grasses so that they can maintain the grasslands. Although the grounds turn completely black after being burnt, before long Kisumire (Viola orientalis) or Sakurasou (Primula sieboldii) begin blooming to color the black grounds. In May, the grounds are covered with fresh green again, with many creatures bustling about vividly.

Summer is blue

In early summer, Miyamakirishima (Rhododendron kiusianu), begin blooming and paint the mountains pink. Many people from all over the world come to Kuju to see this unique scenery. In the marshlands, many flowers such as Kisuge (Hemerocallis vespertina) and Nohanashobu (Iris ensata var. spontanea) bloom. Higotai (Echinops setifer), which is a blue round flower, also add colors to the grasslands. Many creatures, colorful flowers, and fresh greens are busy to brighten up the short summer in the highland.

Autumn is red

In September, autumn flowers like Shirahigeso (Parnassia foliosa var. nummularia), Akebonoso (Swertia bimaculata), and Waremokou (Sanguisorba officinalis) begin blooming one after another in the grasslands, letting us know autumn has come. In the middle of October, the leaves on the trees around the top of the mountains start changing their colors into red, yellow, and golden brown. Gradually, the autumn leaves color the mountains from the top to the bottom. The first snow falls on the mountains in November. The season changes from autumn into winter quietly and slowly…

Winter is white

Though Kyushu is the southern-most main island of Japan, the winter in Kuju is unbelievably cold. In Bogatsuru, the temperature sometimes falls down to -20 degrees. Miike pond, which is just below the peak of Mt. Nakadake, is frozen and you can walk across on the ice. Kurasame Fall also becomes icy. In the highlands, the snow lies as deep as more than 50cm. On the snowy ground in Tadewara, you can find the footprints of a fox, a hare, and a marten. With them you can feel the breath of creatures even in the silence and stillness of the snowy field.
