How Many Shrines in Shinjuku-ku? At least 82

March 31, 2018: I have just added three in-ground shrines at Meotogi Jinja to the list below, bringing the total for Shinjuku to 82.

​

According to The Association of Shintō Shrines there are 60 shrines registered with it in Shinjuku-ku. (Japanese)   I have come up with a number of 82: the difference stems from the large number of secondary in-ground shrines which are not registered with the Association. In the following table the names of the main (host) shrines are in bold characters, the names of the secondary shrines not. In all cases the addresses of the latter are identical to those of the former. 

Of the total 34 main shrines, 11 (32.4%) are Inari, as are 12 (25%)  of the 48 secondary shrines. Thus, of the total 82 shrines in Shinjuku 23 (28%) are Inari, higher the 23% nationwide figure implied in Kamata’s table. The second largest shrine grouping, with 24,000 shrines, is Hachiman and it accounts for 4 (11.8%) of Shinjuku’s 34 main shrines, but for none of the secondary shrines.
