My family spent months planning to squeeze Kyoto, Nara and Osaka it to 2 days, with Misaki’s help we made that happen. He was kind, informative, organized and a pleasure to talk and walk with. I’d love to spend a month with him and his depth of knowledge. He was excellent at making things fun. He kept my children (11-20yrs) involved and engaged.
