Halal In Japan Website Search Buttons
On almost every page you will find 2 brown buttons:
Click/Tap on each and it will take you either to a certain part of a page that has listed the shops or restaurants in the Area "if there is any", or to the general List on the Halals page.
For example, at the bottom of sightseeing pages, there is a map and under the map you can see the address of the area you are reading about.
The page Asakusa in Tokyo; under the map you will find "Asakusa – Taito-ku, Tokyo". Asakusa is a district in Taito Ward which is one of the 23 wards of Tokyo.
The restaurant button on Asakusa page will take you to the Taito-ku section of the Tokyo's restaurants page, where you can see the list of the restaurants in the area.
In the same way, the shop button on Asakusa page will take you to the Taito-ku section of the Tokyo's shops page, where you can see the list of shops in the area.
If you know where you are, you can easily find the closest restaurants/shops to you. You can ask the Police Box "Koban" near the train station and they will provide you with a black and white map of the area. If you show them the list of the restaurants on your Smart Phone or Tablet they would mark the places on the map for you.
The Information Desk in your hotel would do the same.
