🐕 Inu no Hi（戌の日） | Day of the Dog
In Japan, Inu no Hi is a day that corresponds to the zodiac sign of the dog.
Because dogs are known for having smooth deliveries and many offspring, this day has long been associated with prayers for safe childbirth.
Traditionally, around the Inu no Hi in the fifth month of pregnancy, families visit a Shinto shrine to offer anzan kigan—prayers for the health and safety of both mother and baby.
It is also customary to wear a haramaki (maternity belly band), often called Iwata-obi, as a symbol of protection.
Beyond childbirth, Inu no Hi is seen as a meaningful milestone that strengthens family bonds and expresses care for new life.
Good for:
prayers for safe childbirth, maternal and child wellbeing, gentle protection and family intentions
🌟 Tensha-nichi（天赦日）
Considered one of the most auspicious days in the traditional calendar.
Often chosen for major beginnings and important steps.
