Less smoking in Japan

I was very pleased to see this sign in a local restaurant last week. Many restaurants are smoking anywhere, some have dedicated areas (but no physical separation), some even have enclosed areas. This sign says that starting from Nov 1st, the whole restaurant is no-smoking. This is from a cheapo ramen chain called 天下一品. I've no idea if this is across the chain or just my local but it's nice to see some movement in this direction.
