Hello all

, I am going to Japan on the 20th with my mother and brother and a family friend and their daughter. I am very excited as I've wanted to go to Japan for quite a long time and find Japanese culture very interesting. I have a few questions and it would be really appreciated if you could answer them or give me any suggestions/advice.
This is our rough iterinary so far: We begin our journey with a few days in Tokyo: the first few days we are going to Tokyo Disneyland and then Tokyo Sea (although I'm not sure this is the best option but the others have decided this).
Day Three: We then have a free day which we are probably going to do shopping/sight seeing.
Day Four:The following day we are going to Osaka and in Osaka we are going to the Aquarium and sight seeing.
Day Five: The next day when the family friend and daughter is at Universial Studios, we plan to go to Kyoto and visit shrines, gardens and if possible find a place to experience what it is like wearing a Kimono.
Day Six: We return back to Tokyo
Day Seven: Tokyo
Day Eight: We travel back home.
We have accomadation sorted and a rough plan but there are still a few things we need to work out.
There are a few things we would like to do that we haven't worked out how or when we are going to do them. We would like to go to a Sumo match and a karaoke booth that allows people under eighteen. I'd love to visit a Cat Cafe and if we had time to go to an Onsen or a tea ceremony. Where can we do these things/how much will they cost?
My brother loves Pokemon and some other anime shows, as well as games so we are defitnely going to The Pokemon Centre and Super Potato. Is there any other places we should go that he would like?
I am interested in visiting gardens, shrines, parks as well as shopping.
What are some of the best gardens, shrines and parks that we should visit in Tokyo, Osaka or Kyoto? I've heard that Meji Shrine is very nice.
I'd love to buy a second hand kimono at a reasonable price. Is there anywhere in particular I should look for a second hand kimono? How much would one cost roughly?
I'm also interested in western Alternative Rock music and I love record exchanges so a record store would be somewhere I'd enjoy visiting. Is there any record stores in Tokyo we should visit specifically?
I like a few anime shows especially classic ones like Sailor Moon as I used to watch it when I was growing up and would love to buy something Sailor Moon like a figurine. What stores in Tokyo and Osaka would stock Sailor Moon things, any you could recommend?
I collect Maneki Neko's and love cats. I also like 'people watching', as I find it interesting. I would like to experience as much of Japanese culture as time allows. Kawaii stores and 100 yen stores are also places I'd like to go to. Also is there any certain stores or suburbs which sell souvenirs at a reasonable price? I also would like to visit a capsule hotel.
I also need to buy a few gifts for friends, mostly pokemon stuff but I have a friend that loves KHR- Katekyo Hitman Reborn and it would be great if I could find her some KHR items.
I'm also a Pescetarian (I only eat fish once a month as my parents say I have to) but I prefer eating Vegetarian food. I've read that it isn't always easy to find Vegetarian food in Japan, is this true? Are there any restaurants/cafes you recommend?
Sorry for all the information and questions. It would really be great if someone could get back to me.
Thank you,so much
