This ukiyo-e made by Totoya Hokkei 魚屋 北渓 (1780-1850) is one of three pictures of a series. This one is called: First Dream of Mount Fuji in a Set of Three 初夢三番 富士.
Hatsuyume (初夢) means the first dream in the first night of a new year, which is foreseeing the future of the coming year. According to the traditional Japanese calendar January 2 is therefore named hatsuyume. Mount Fuji is always a symbol of good luck.
You can find a Japanese inscription of the poem at the website of the Museum of Fine Arts in Boston.
