Here is a link to Naoki’s blog: http://higashida999.blog77.fc2.com//
But here’s the deal: it is entirely in Japanese (of course). So if you want to read it and you are running Internet Explorer you are out of luck. If you read it in Google Chrome it will ask if you want to translate it into English and it will do it for you. In Firefox you will have to get an add-on by going into the menu, selecting ‘add-ons’ and searching for a translator.
It won’t be a perfect translation but you’ll at least get a sense of what Naoki is like as an adult.
