The most difficult thing in writing about Japanese stuff is to translate proper nouns.
SMO(ソーシャルメディア最適化)実践テクニック (Social Media Optimization Practical Technique). The book gave me a good overview in the area. Adds a Japanese perspective to the social media optimization. The book is written for non-experts in this field and comes with a number of illustrative cases. The last chanper is an interview with Tomoharu Sumi, a Japanese expert in this area.
The book is worthwhile for those interested in SMO and have a basic understanding of SEO/SEM. (Note: you should be comfortable with reading Japanese.) And this is way cheaper than attending seminors of this sort. If you only learn things when you attend a lecture, please prepare for the cash and/or giving your and your company’s information.
