## What is ARu?

Whether you live in Japan or you're just visiting.

Everyday life in Japan is full of unspoken rules no one tells you about, and little "wait, how do I do this?" moments that pop up all the time.

ARu is your everyday guide to living and traveling in Japan, made for foreigners.

Ask anything. Get answers fast. Understand the why.

■ Japan, more fascinating
Stuck? Ask the AI anything about life in Japan. Ask in your own words and get a clear, easy answer right away.

■ Not sure? Just ask ARu
"Can I slurp ramen?" "What's a My Number card?" — hundreds of real questions covering daily life, travel, food, etiquette, and even emergencies.

■ Turn "huh?" into "ah, I see"
ARu doesn't just tell you the rules. It explains the reason behind them, so things finally click.

■ The more you know, the more you'll love Japan
Go deeper with in-depth articles and timely info — from traditional culture like tea ceremony, martial arts, and calligraphy, to the manners and topics worth knowing right now.

■ Your own Japan begins here
Connect directly with experienced locals and Japanese mentors who've walked the same path, and ask them anything. Residence card paperwork, your first train ride, onsen etiquette — with ARu, living and traveling in Japan becomes something you can truly relax and enjoy.

Welcome to Japan.

### 5/5 — Very helpful

*2026-07-09*

Understanding how to behave appropriately in Japan can be quite difficult.

The rules are something you can look up, but there are also many unwritten customs and manners that aren't official rules, yet people are still expected to follow them.

That's why I think this app is really useful. It allows local Japanese people to explain these cultural norms and etiquette—things that are difficult to discover on your own.
