There are many differences between the two languages, but it takes time to spot them. Japanese is often written in kanji, which is Chinese calligraphy but is also made up of katakana and hiragana, two alphabets used only by the Japanese language. The language itself is very different, because it is a different country, culture and lifestyle. The number system is taken from the Chinese language, but it should be noted that Japanese has its own counting system that isn't recognized by many people striving to learn Japanese. It should be realized that these are two separate languages, and it would be a much shorter list to recognize the similarities rather than the differences.

I've never heard of a Chinese geisha. It's a Japanese word, and traditionally a Japanese profession.
THE WORD and THE DRAMA
"Teriyaki" is a Japanese word, and in approximation, would equate to 照燒 (based on cultural/language influences between Chinese and Japanese)
The Japanese writing system is based on three main scripts: Kanji (Chinese Characters), Hiragana (a set of symbols that make up different words), and Katakana (another set of symbols used for sounds and foreign borrowings). If you learn to reconize the symbols of Hiragana and Katakana you will be able to defrinciate between the Chinese and Japanese written language. You will only see Kanji in Chinese while Japanese is fused with their own symbols. A chart illustrating the Japanese 'kana' symbols can be found in the related link below.
While the Chinese writing system was imported into Japan and formed the basis of Japanese writing, the origin of the Japanese language is less certain. Its roots may have been brought to Japan by settlers from continental Asia or from nearby Pacific islands. The Japanese language is not part of the same language family as Chinese, although a large portion of the modern vocabulary is borrowed from Chinese.
japan is surrounded by water and china is not.
Latin and German are western languages, so they use letters just like how we write English. Japanese, Chinese and Arabic are eastern languages, so instead of using letters, they use characters that consists of strokes.

The Chinese and the Japanese are two entirely different people and cultures. Therefore, the literature will be different, written by two different people's authors.
