Yes that anchor variant is Kure Naval Arsenal.
Is there an S stamped near the 1/6 or a Japanese character 昭 or 昭和?
S would indicate the Showa reign, 1 the first month, and 6 the 6th year of Showa. Therefore January 1931.

There are no other markings on the case. Could the 1/6 be any other date?
That very simple format, without an imperial period character, tends to correspond to Taisho period munitions; so January 1917 (Taisho 6th year).
