Also to add on what was not mentioned , you have to bring in extra coins inside the Live House venue/s as there's a separate drink charge imposed
For Zepp venues , it's 500 Yen but they will also give you a token item & each Zepp venue they will give you a different item
For Zepp Nagoya , it's a drink strap which my sister obtained when she went to see GRANRODEO perform
For Osaka's Zepp Namba , they gave both of us a key ring strap with the Zepp logo on it
After you pay the fee once you're inside , the staff will give you a token coin to exchange for the drink , be it a small water bottle or a cup of beer . It's not a must for you to exchange immediately as some would only do that after the concert finish , the upside for them is that they would get a much better/closer view to the stage
I don't know for the other Zepp venues but for Zepp Namba , the 1st floor there were barriers inside which's a good thing as things got chaotic as the concert progresses on while the 2nd floor has seats
You will see something like this outside of the venue prior to entering
I don't know how it will be like for Kuu's but it should be something similar . At least the staff didn't used a loudspeaker unlike the 1st time I went (where my ticket number was so crappy but yet somehow I ended up 3rd row centre inside the venue LOL)
Lastly , you cannot bring a lot of stuff inside a Live House venue unlike a Hall let alone an Arena/Dome . You only can bring the bare minimum items (like a small pouch with your concert ticket) , everything else have to be deposited inside the lockers that're available in Zepp . If not you can just deposit your stuff in the nearest train station
Of course you should only do that after you bought the concert goods you want cos once everything's inside the locker , you cannot take them out and you have to rent another 1 once it's open
