I’m the founder of KanJava which is Japanese JUG. We’ve managed this JUG for 8 years. We have over 600 members and hold a event almost every month in Osaka or Kyoto. Each event has at least 40 participants. When you come to Japan, please contact me. Then we will have a event and ask you to be a guest speaker! Of course we will take you around Kyoto or Osaka. Kyoto is the most popular city for sightseeing in Japan. There are many old temples and Geisha-san walk around in the specific area.
