NyanBazWhat kind of kid were you when you were little?
NyanBazYou were interested in computer programming even in those days. When did you start on puzzles?
NyanBazWhen did you get to know Nikoli?
NyanBazHow'd you know. Then, when did you return to puzzles?
NyanBazYou have a great brother. And incidently, this brother of yours is a puzzle author too.
NyanBazGood to hear that. In the latest issue "Puzzle Communication Nikoli" Vol. 124 there is a lot of work by your brother, more than work by you. Do you you feel sorry about that?
NyanBazWhen did you start making puzzles?
NyanBazThen you kept it up ever since?
NyanBazIs that how you go about it. Did you ever think it good that you have continued with puzzles?
NyanBazDo you still like Slitherlink?
NyanBazAre there puzzles you don't really like?
NyanBazYou're good at making easy problems?
NyanBazI think there are different kinds of pleasant. What is pleasant for you?
NyanBazFor yourself, the flow of the problem, do you think it up when you are making it, or is the thinking done before making the problem?
NyanBazThere are a lot of authors who want to make strange problems or problems with flashes of surprise. Don't you want to make such problems?
NyanBazWhen and where do you make your puzzles?
NyanBazRight, Sudoku and Kakuro can be solved without looking at the whole grid.
NyanBazYou said it. (laughs) Then, you always make puzzles in longhand?
NyanBazLet me see? Oh, beautiful! But this is not a fair copy just notes, isn't it?
NyanBazI make puzzles in freehand too, but it becomes messy with notes to myself and modifications in the work. But this beauty is wonderful!
NyanBazThen are there things that you cannot get across when you make your puzzles?
NyanBazYou sure think about it all. How many puzzles have you made so far?
NyanBazThen, is there a masterpiece among them?
NyanBazWhat is your ideal puzzle?
NyanBazWonderful! A last question, what is your message to the solvers who have enjoyed your puzzles.
