Sorry, due to the lack of detailed information about the tourist destination, it is not possible to propose a specific structure for the article. Information about a Japanese restaurant called 'とこま' in Shimoda City has been provided, but this is just a store information and is insufficient to talk about the charm as a tourist destination.
Writing a tourist article requires detailed descriptions of the history, culture, nature, attractions, and activities that tourists would be interested in. Simply providing the address, photos, and reviews of the store is not enough.
If you could provide information about the overall tourist resources in Shimoda City, we could then propose a comprehensive structure for a fascinating tourist article capturing the various aspects of this charming region. If you have the information, please consult us again.
