Opening in Ryogoku this month (on the 22nd, to be exact) is the Sumida Hokusai Museum. Here’s a description from Time Out Tokyo:
Spending a day in Ryogoku is set to become even more of a necessity for tourists from this November, when the neighbourhood that already houses the Edo-Tokyo Museum and the Kokugikan will see the opening of a museum dedicated entirely to Edo-era Sumida’s most famous son – ukiyo-e superstar Katsushika Hokusai. In addition to viewing displays of the woodblock print wizard’s countless masterpieces, you’ll get to learn about Hokusai the man, his life in Sumida and what the city looked like between 1760, when Hokusai was born in Katsushika, and 1849, when he died and was buried at Seikyoji Temple in Asakusa. Visitors will also want to check out the full-scale master’s atelier, a reconstruction based on a painting by Hokusai apprentice Iitsu Tsuyuki.
