How much is $100 in Tokyo?

Excuse me, could you please clarify for me how much Japanese yen would be equivalent to $100 in Tokyo? I'm aware that exchange rates can vary, but I'm trying to get a rough estimate for budgeting purposes. I'm planning a trip to Japan and want to ensure I have enough funds for my stay. Could you provide me with the current or an approximate conversion rate for this amount? Thank you in advance for your assistance.
