Announcement for the September “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.

Why don't you and your child take a moment during your summer vacation to take a little peek into the world of Zen at a small, historic zazen meeting in a quiet residential area near Shinjuku?　Sometimes the experiences we have in our childhood become memories that last a lifetime. We have planned this event in the hope of providing such an irreplaceable opportunity. On the day of the event, you will experience a short zazen session, a Zen talk by the abbot, and Zen calligraphy. Women will be on hand to provide support.

The June sesshin was held from June 18 to 22, 2025. Six students practiced under the guidance of Master Genryo.

The April Friday evening and Saturday zazen meetings will be held on the following dates. Sunday Zazen Talk will be held on Sunday the 26th. Please feel free to join us. We look forward to seeing you there.

The Friday evening zazen session on April 10 and the Saturday zazen session on April 11 will be cancelled due to preparations for the Buddhist memorial service.
