。
She's going to Sendai this spring.
Literal
She [topic-は] this spring Sendai [to-へ] go.
仙台 (Sendai) is the largest city in the Tohoku region of northeastern Honshu and the capital of Miyagi Prefecture. It's known for its summer Tanabata festival (one of the three largest in Japan) and 牛タン (beef tongue), a local culinary specialty. へ marks the destination, slightly more written-feeling than に for movement. Like other Japanese 'going' sentences, the present-tense form covers both habitual and future use; この春 ('this spring') anchors the time. April is also the start of the Japanese fiscal and academic year, so spring moves are common — driven by graduations, new jobs, and transfers.
