teamLab has problems with foreigners if they have a disability. In June and July 2019 you will not get access to the nice exhibition if you have a disability and bought the disability ticket. Even it is not possible to pay the difference to a full price ticket. Thus be careful to buy full price tickets in advance otherwise they will kick you out.
(Later I found the explanations on their website A disability certificate issued in Japan is required for tickets for June and July. From August, tickets may also be purchased with a disability certificate from other countries. )
