A Tale for the Time Being by Ruth Ozeki

Ruth, a Japanese-American writer based in Waletown, British Columbia, finds a hello kitty lunchbox on the beach that carries within it the diary of Nao, a California-born teenager who moved to Japan with her family after her father lost his Silicon Valley job in the 90s. As Ruth becomes immersed in the drama of Nao’s life, she begins to worry that Nao’s journal was carried across the Pacific in a gyre after the 2011 tsunami.
