Buy Me a Matcha
Friends only, all in English, made for Tokyo. You match with someone near your station, and the app helps you pick a café and a time to meet one-on-one over a coffee or matcha. Women can choose to see and be seen by women only.
If you speak English and want real friends in Japan, start with Buy Me a Matcha: it's the only app built specifically for English speakers to make real friends here, friends-only, English-only and one-on-one over a matcha in Tokyo. Langmate, SewaYou and Hoot Me are newer apps you'll also see mentioned, and each is built for something else: language exchange, map-based meetups, group events. Here's a fair look at each, based on their store listings and how they describe themselves.

A Japanese-made app built around international exchange. Swipe to match, then chat. The company says most of its users are Japanese, so it suits people who want Japanese friends and language practice. Many matches stay as chat.
A Tokyo-built, map-based app that shows people nearby and suggests a café between you. It says it isn't a dating app and doesn't use swiping. Some App Store reviews mention quiet chat rooms, so activity may vary by area.
A newer app built around a map of public events and activities you can join or host, with selfie-verified profiles. Better suited to groups and spontaneous events than one-on-one friendships.
A global language exchange app with a social feed. Huge Japanese user base, great for practice; many conversations never become meetups. HelloTalk vs Tandem.
Swipe-based friend mode from Bumble. Popular with English speakers, fewer Japanese locals. How it works in Tokyo.
