Red Chokeberry (Aronia Arbutifolia) セイヨウカマツカ/アロニア（西洋鎌柄）

I'm not certain but believe they're red chokeberries. The berries have been there since autumn last year and at that time I disregarded them because of the presence of flowering dogwood's more gorgeous autumn leaves nearby. Now, however, the red leaves are gone and red chokeberries' bright red has finally attracted my attention. They're edible (but not tasty) according to the internet.
