Being muslims simply does not hinder us to travel around the world. We admit that, sometimes, there is a worry on how and where we could perform our prayers. But nowadays, information regarding mosques or islamic communities is now available in most of tourist-destination countries, including Japan. This info was then used to prepare our trip.
We had a whole day in Nagoya, it was thus a must to pay a visit to one of its mosques. In Nagoya alone, there are at least 2 mosques listed on the internet. The one that we went to is about 20-minute away from Nagoya Station.
