Many haikus are inspired by objects in the natural world, such as trees, rocks, mountains, and flowers. To get ideas for your poem, take a walk in a park nearby or go for a hike in the woods. Head to a mountain trail or a body of water like a river, lake, or beach. Spend some time in nature and observe it so you can get ideas for the poem. If you can’t go outside for a walk in an area with nature, try looking at nature photographs and art in books or online. Find a particular nature scene or object in nature like a tree or flower that inspires you. Haikus can also be about a season, such as fall, spring, winter, or summer. You can also focus on a natural event that happens at a certain time of year, such as the blooming of the cherry blossom trees in your neighborhood or the salmon run in the river near your house. Seasonal haikus often focus on a specific detail about the season, naming the season in the poem. Writing about a season can be a fun way for you to describe a particular detail you love about that time of year. Haikus do not all have to be about nature or the seasons. You can also choose a particular person or object as an inspiration for the poem. Maybe you want to write a funny haiku about your dog. Or perhaps you want to write a thoughtful haiku about your childhood toy. Try to only focus on one person or one object in the poem. Haikus are short and you may not have enough space in three lines to write every thought you have about the person or object. To get a better sense of the genre, read haikus that are well known and considered good examples of the form. You can find examples in books or online. Read haikus that are about nature and other subjects. You may read:  Haikus by the Japanese poet Matsuo Basho. Haikus by the Japanese poet Yosa Buson. Haikus by the Japanese poet Tagami Kikusha.  Haikus by American poet Richard Wright. Try finding a resemblance to nature or a metaphor that expresses your feelings shortly. An example may look like this:  Boom, boom, boom, bam, bam!
