Ryokan Taigu's poetry is known for its simplicity, sincerity, and deep connection to nature. His writing style is often described as waka, a traditional Japanese form of poetry that consists of 31 syllables in a 5-7-5-7-7 pattern. However, Ryokan's approach to waka was unique and unconventional, as he often broke away from the traditional structure and incorporated his own personal experiences and emotions into his poems.

One of the defining characteristics of Ryokan's writing style is his use of imagery and metaphors to convey his thoughts and feelings. He often draws inspiration from the natural world, using elements such as mountains, rivers, and flowers to symbolize different aspects of life. For example, in one of his most famous poems, he compares his own life to a withered tree, expressing his acceptance of aging and impermanence.

Another notable aspect of Ryokan's poetry is his use of humor and wit. Despite his reputation as a serious Zen monk, his poems often contain playful and lighthearted elements, showcasing his joyful and carefree spirit. In one poem, he humorously compares himself to a "foolish old man" who is content with his simple life in the mountains.

In addition to his use of imagery and humor, Ryokan's writing style is also characterized by his direct and honest expression of emotions. He does not shy away from expressing his sadness, loneliness, or longing in his poems, making them relatable and deeply moving. His sincerity and vulnerability in his writing have made him a beloved figure in Japanese literature.

Overall, Ryokan Taigu's writing style can be described as lyrical, introspective, and deeply contemplative. His poems offer a glimpse into his inner world, filled with a sense of wonder and appreciation for the beauty of nature and the simplicity of life. His writing style has left a lasting impact on Japanese literature, inspiring generations of poets to come.
