英会話 言語交換カフェ (Language · 1-chōme-17-5 | Tokyo

Down in a Jinnan basement, this cafe runs organized weekly Japanese-English conversation meetups. Reviewers describe an easy entry point: free talk with international friends, a friendly organizer, clear rules that make participants feel safe, and plenty of chance to practice both languages. As one put it, a fun way to meet new people and improve your Japanese.
