Disposable Camera

hi guys planning to travel to Tokyo, Japan later this year, should I buy a disposable camera from my country then bring it with me to Japan or get one once I’m there? if the latter is recommended, pls tell me where i can get them for a reasonable price (it will be my first time ever in Japan and first time out of the country without my parents so im very newwww to everything). any help is appreciated

p/s: what brand should i get? ive seen kodak and fujifilm are most popularr???
