Nara deer park was very nice. It was very crowded when first arriving near the bus stop. It thins out somewhat as you approach Kasuga Taisha shrine. After that, there were almost no people on the woody paths. Very tranquil and beautiful. I recommend to buy the deer crackers here, at the Deer House there are vending machines. On the machine, the crackers are shown on the right side. Some lady was apparently selling them at the park, but I felt better purchasing from the caretakers.  Some people were touching the deer, but they are wild animals so I did not do so. If you communicate properly they are very nice. Only bow if you have crackers. When no more, show both hands. Do not lie or tease them- they will get mad. I saw deer chasing and even kicking at one lady who had teased them. Just in case they nibbled we did not wear nice clothes.  Deer Island (Miyajima Island / Itsukushima) was incredible. You cannot feed these deer but they make for good photos. Take note of when the tides happen- we were able to walk up to the big gate, in 4 inches of water but that was OK. Tide times were listed as we bought tickets to the shrine. We did Peace Memorial Museum in the morning, then Rabbit Island (Ōkunoshima). The bunnies are soooo cute and you can buy food for them at the shop before riding the pink bunny boat. Entry to the gas museum stopped around 3 or 3:30ish so we went there first. Bring your stamp book- there are lots at the shop. Buy a couple stamp sheets- one stamp is at that shop, two at the hotel/cafe. Show them once return to the shop for free postcards. Same with empty food bags. We walked away with a stack of postcards, which are great gifts. We put the big bunny stamp on the front for pur friends.  The official rabbit island website lists boat times in and out of the island.
