A casual modern guesthouse that mixes aspects of hotel and ryokan. Much less intimidating than a traditional ryokan, with more relaxed rules (e.g. shoes may be worn up to your room) and some concessions to western sensibilities (baths are shared, but there are locks on the doors for privacy while using one).
The staff have limited English but are friendly, used to foreign guests, and good at communicating. The food is excellent - as with the accommodation, it is a fusion of traditional concepts with modern/western influences, and considerable effort clearly goes into the menus; it is here that the limited English does unfortunately mean that non-Japanese-speaking guests will miss out on a lot of the detailed explanations, but the flavours are quite capable of speaking for themselves.
The main downsides are the location, which is a bit out of the way - but easily walkable from the ferry port unless you have heavy luggage (and you’re not going to spend more than a night or two on Miyajima, so consider sticking the suitcase in a coin locker and just bringing a lighter bag!); and the curfew, which means you won’t get to wander the streets at night, if for some reason you were hoping to do that.
