Haiku magazine Hototogisu, directed by Kyoshi Takahama, produced many brilliant haikuists.
The first wave, in Taisho era, was composed of the poets such as Kijo Murakami (1865 ~ 1938), Suiha Watanabe (1882 ~ 1946), Fura Maeda (1884 ~ 1954), Dakotsu Iida (1885 ~ 1962), Sekitei Hara, etc. These poets are generically called "poets of Taisho Hototogisu".
The characteristic of their poems is to describe the nature and to express the worship to the eternal and mysterious existence, in a traditional style with a lofty tone. And their themes are the great landscapes (mountain, valley, sea, or sky) or the life of men in the great nature.
I present poems of Sekitei Hara. He lived in East Yoshino, village in the heart of a mountain. He described rigorous nature and succeeded in expressing the acute beauty, which gave a shock to the haiku world.
