Thanks. Found it! Indeed Yamanotera - this area of Sendai is still named after the temple. As most places in Sendai it burned down during the war, though in this case not as a result of bombing.

Very suburban area nowadays - I hadn't assumed there was much of historical value there, and even if it's just a reconstruction now, maybe I'll drop by.
