Last autumn, our planned tour to Izu Oshima was unfortunately canceled due to a typhoon. Despite our hopes, the ferry services were suspended, and we were deeply disappointed.
We are excited to announce a rescheduled tour this April, skipping the cold winter season. Please join us to witness the beautiful starry skies of Tokyo during the new moon. We look forward to your participation!
