@AmazingAng CC: @thurendous WTF Soliidity 101 Last "Lesson 15" has been translated into Japanese! I've had a check after pushing the local repo into remote and modified that!

So now all the 101 chapters or lessons that were assigned to me tentatively have been FINISHED! Thank you very much for such an opportunity!! ;D
