I create my second original "mind the doors" sticker.
Following the last work, this time also resembles the Osaka Municipal Subway's one, a little girl whose hand was being caught into door pocket and crying was pictured, and is planned to be laid out at the eye level of the little children to aim to be easy to see and understand for them.
The carriage door isn't the one traced from an existing commuter train's.
Though the last work had an illustration only, this time consists of an illustration and messages both in Japanese and English, which is considered to warn the passengers of avoiding the accident, not to touch opening doors, which must be better than "mind the doors".
Recently, some railway operators in Japan, such as Hiroshima Rapid Transit ASTRAM Line AGT and Keio Corporation (both of them Japanese only) changes or adds the sticker with this kind of message.
Around 30 or 40 years ago, some railway operators such as Teito Rapid Transit Authority (Tokyo Metro) and Tokyu Corporation introduced the side doors with small glass or sticker the one-third or half size of the glass. In my opinion, they had an effect on telling the children not to come close to the doors, but seemed to be unfriendly without the message not to touch the doors.
