Every third Saturday of the month, we hold sesshin, an overnight intensive zazen practice from Wednesday evening to Sunday noon.
The December sesshin was held from Wednesday, December 17 through Sunday, December 21. From Wednesday to Thursday, after early morning zazen, participants returned to their normal daily routines, including leaving the dojo to go to work, and then returned to the dojo in the evening for zazen and overnight stay, spending time intensively facing their own selves.

Announcement: July "Zen Tea Gathering"
If you’ve ever wanted to try matcha at a tea ceremony but hesitated because you didn’t know the proper etiquette, we’ll explain the basics in the traditional tatami room at Kobo-in Temple in Nakano Ward, Tokyo—just a short distance from Shinjuku. At Kobo-in, we offer tea ceremony lessons as part of our Zen practice. Through a short 10-minute zazen meditation and the tea ceremony etiquette, you’ll experience the importance of focusing on each and every moment of “now.”
After that, please watch a demonstration of the actual thin tea ceremony and enjoy the main sweet and thin tea.
Fee: 1,500 yen (Advance registration required)
