There's actually a Japanese programming language (created around 2005) that is highly readable and natural - Nadesiko. Here's the first tutorial in Japanese, with executable snippets:

https://nadesi.com/v3/doc/index.php?%E3%83%81%E3%83%A5%E3%83...

  「こんにちは」と表示
  Display 「Konnichiwa」

  5に6を掛けて5を足して7で割って表示。
  Multiply 5 by 6, then add 5, then divide by 7, then display it.

Sample program:

  「身長は何センチですか」と尋ねる。
  Ask "What is your height in cm?"
  身長Mはそれ÷100
  heightM is that divided by 100.
  標準体重は２２×身長M×身長M
  optimalWeight is 22 x heightM x heightM.
  「標準体重は、｛標準体重｝kgです。」と表示。
  Display "Your optimal weight is {optimalWeight} kg."

Since it's basically natural language, it's a really nice language for introducing Japanese speakers to programming!

There's also this language, Wenyan-lang, that imitates classical Chinese: https://github.com/LingDong-/wenyan-lang Sample:

Wenyan:

  吾有一數。曰三。名之曰「甲」。
  We have a number. It is 3. Its name is n.
  為是「甲」遍。
  Done n times:
    吾有一言。曰「「問天地好在。」」。書之。
    We have a phrase. It is "問天地好在". Write it.
  云云。
  End.

Equivalent JavaScript:

  var n = 3;
  for (var i = 0; i < n; i++) {
    console.log("問天地好在。");
  }
