One of my favorite places in Japan - Miyajima. I've visited all the shrines and temples, climbed to the top of the island several times and have stayed at various hotels on the island and in Miyajimaguchi where you catch the ferry to Miyajima. The energy here is connected to the Sinsoji Temple in Tokyo (below).
My very first trip to Tokyo was through the company, Voice, Inc. The owner, Masumi Hori, had me stay at the company condo located in the Asakusa area of old Tokyo. Sensoji was a short walk - I visited every morning to get my mind into the culture.
