I've recently learned that many high-end restaurants in Japan, such as Sushi Saito or Matsukawa, are basically private clubs where to get a reservation you either already have to a regular or be invited by a regular or by the the proprietor. How would I, as a non-Japanese person, get into one of these establishments? Should I be eating at less exclusive restaurants whose chefs are prominent in the Japanese culinary scene and trying to get them to vouch for me? Should I be trying to become friends with people who are already regulars and seeing if they'll invite me to go with them? Evidently, 外国人 are somehow getting in to these places, because you can see their reviews on Instagram, so don't tell me it's impossible. If anyone has any firsthand experience, I would be interested to hear about how they did it.
