The Metropolitan Museum of Art in New York City is currently featuring an outstanding exhibit: Art of the Samurai Japanese Arms and Armor, 1156–1868. The ambitious loan exhibition will bring together 214 masterpieces, including 34 National Treasures, 64 Important Cultural Properties, and six Important Art objects, a number of which have never traveled outside Japan. The several meitō being displayed include the exceptional 12th-century blade called Ôkanehira, disputably known as the greatest of all Japanese swords.
The last day of the exhibit is January 10, 2010.
While we will not be able to attend ourselves, its currently seems like a worthwhile exhibit for anyone interested in nihontō who can attend. A collection this large available for viewing in one place is probably a once-in-a-lifetime opportunity.
