History
Only limited records survive regarding the detailed history of its main image and halls, but as a temple of the Shingon Buzan-ha school it has walked this ground alongside its parishioners for generations. The Wakaba area has been known since the Edo period as a district rich in temples and shrines, and Aizen-in is thought to form one part of that temple-town history. For the exact founding year and treasures, it is best to check official information when you visit.
Access
The temple stands at roughly 35.686 degrees north, 139.724 degrees east, in Wakaba, Shinjuku Ward. It is within walking distance of Yotsuya and Shinanomachi stations on JR and subway lines, tucked into a quiet residential district full of gentle slopes. As it may face a narrow lane, first-time visitors are advised to confirm the gate's location on a map app while approaching.
Best season
You can worship quietly year-round, but spring to early summer, when fresh greenery lines the Wakaba slopes, and winter mornings, when the clear air sharpens the outline of the halls, are especially recommended. Those who wish to avoid crowds will find weekday mornings the calmest time.
