Update : The 5.8 aftershock near the coast was far more dangerous (due to the shaking danger) than the earlier M6.9 mainshock. JMA reported a 5+ intensity which is seen by Earthquake-report as potentially dangerous for damage.
JMA 5+    Hashikami-cho Dobutsu*
JMA 4    Hachinohe-shi Uchimaru*,  Hachinohe-shi Nangoku*, Sannohe-machi Zaifu-kojimachi*, Aomori Nambu-cho Tomabechi*, Aomori Nambu-cho Taira*
JMA5+ means :
* Many people find it difficult to walk without holding onto  something stable
* Dishes in cupboards and items on bookshelves are more likely to fall
* Unsecured furniture may topple over
* Unreinforced concrete-block walls may collapse
