This is the only Japanese altcoin. Japan is the only country giving digital currencies a legal status as JPY

- Launched in 2014, Inflation rate is now lower
- Segwit is locked in
- Can be bought against fiat (JPY) on Bitflyer, Zaif and Bitbank
- Strong community in Japan, you can use Mona to buy credits for video games or IT products
- Visibility is getting stronger due to a media campaign in Tokyo (see above posts)

Definitely a coin to have in a crypto portfolio
