I’m going to start out with a disclaimer: Every person- and consequently every situation- is different. I am going off of my experience and some discussions with my Japanese friends and friends who have lengthy experience with the culture.
The Westerner will think the Easterner isn’t interested in a relationship with him/her.
Started in 2005, Japan Cupid is part of the well-established Cupid Media network that operates over 30 reputable niche dating sites.
As one of the largest Japanese dating sites, we have thousands of Japanese women signing up everyday interested in meeting someone like you.
Everything before that is considered getting to know each other in a friendly manner.
In the West we would argue that dating is simply getting to know someone better with romantic intent to see if you would like a relationship with them, so that the time spent outside of the group would be considered dates.
