Let's solve the problem step by step.

First, let's find the number of local visitors:
Number of local visitors = (1/4) * 5400 = 1350

Next, let's find the number of foreign tourists:
Number of foreign tourists = Total number of visitors - Number of local visitors
Number of foreign tourists = 5400 - 1350 = 4050

Now, let's find the number of foreign tourists from Malaysia:
Number of tourists from Malaysia = (1/5) * 4050 = 810

The remaining foreign tourists are from Japan and China. Let's assume the number of Chinese tourists is x. Therefore, the number of Japanese tourists is x + 200.

Since the total number of foreign tourists is 4050, we can write the following equation:

x + (x + 200) + 810 = 4050

Simplifying the equation:

2x + 1010 = 4050
2x = 4050 - 1010
2x = 3040
x = 3040 / 2
x = 1520

So, the number of Chinese tourists is 1520, and the number of Japanese tourists is 1520 + 200 = 1720.

Therefore, 1720 Japanese tourists visited the zoo.
