NB: In our experience Japanese guys are far less likely to flake on dates.
Japanese women tend to want to look, feel and be their best whenever they are on a date so expect cancellations when weather is bad or when she’s in a bad mood, or tired.
However, because so few foreigners live in Japan, their best chance of meeting one in their normal lives is if they get lucky enough to have a native English (or other language) speaking teacher in junior high or high school.
A really common mistake that most guys make when they communicate cross culturally is they think their subtle, razor sharp wit and wordplay will impress.
The other really easy way to meet Japanese girls is through Language Exchanges.
These are one-on-one meets where you practice speaking Japanese with a native while they practice speaking English/French/German/Italian/Korean/etc with you.
As a guy looking to meet Japanese girls who are looking to meet foreign guys though, your best bets are what are called “International Parties” and “Language Exchanges”.“International Parties” are parties organized specifically to bring foreigners and Japanese folk together and give everyone the opportunity to meet and interact in a safer environment than clubs or bars provide, and are much more relaxed events that are usually held on Friday or Saturday evenings, with some events earlier in the afternoon.
Many of the organizers also run other kinds of seasonal events as well.
