The temple is located along a beautiful, quiet traditional street, and its exterior is especially striking. It marks the 7th stop on your Zenkoji Seven Lucky Gods pilgrimage (Shichifukujin Meguri) and is dedicated to Bishamonten, the God of Victory. As one of the Four Heavenly Kings, he is believed to guard the northern direction—which fits perfectly, since this is the northernmost point of the route (aside from the final 8th stamp at Zenkoji itself).
The temple closes at 4:00 PM, and the stamp here is placed by an attendant inside on the left for a small fee (100 yen). After that, you can head to Zenkoji to finish your pilgrimage with the central and final stamp, also available until 4:00 PM.
A small heads-up: when I arrived here around 3:30 PM, the priest kindly offered to place the final stamp for me, just in case I didn’t make it to Zenkoji in time. I politely declined since Zenkoji is only about 10 minutes on foot (or 5 minutes if you walk briskly, which I did). So don’t be surprised if you’re offered the same—they seem to keep the final stamp on hand for situations like that.
Note: Take off your shoes before entering.
