Although it has origins in China, tea became popular throughout the entire Eurasian landmass several centuries ago, and many different cultures now observe their own tea traditions. Tea certainly has a special place in the culture of Japan. This spring (Tuesday, March 19, at 10:30 a.m., noon and 1:30 p.m.; Wednesday, April 10, at 10:30 a.m., 1:30 and 4:30 p.m.; and Thursday, April 11, at 8, 9 and 10:30 a.m. and 1:30 p.m.) Sacramentans can learn more about the traditional Japanese tea ceremony at the Sokiku Nakatani Tea Room and Garden at Sacramento State University's library (6000 J Street). These ceremonies, called chado, are free and open to the public. Each chado presentation lasts 75 minutes and comes with a bowl of green tea. Some attendees will be chosen to sit on traditional mats and participate in the ceremony. Visit http://apps.lib.csus.edu/tearoom for more information.
