What two groups of people made their way to Hawaii in the 1800s and why did each go?

In the 1800s, two significant groups that migrated to Hawaii were American missionaries and laborers from China and Japan. American missionaries arrived in the early 1820s with the aim of spreading Christianity and Western education, significantly influencing Hawaiian society and culture. Meanwhile, laborers from China and Japan came to work on sugar plantations, driven by the promise of employment and better economic opportunities, as Hawaii's agricultural economy expanded during this period.
