This study aimed to share the practical results of teaching activities in Japanese as a foreign language in senior high school. The teaching activities refer to The Second Foreign Language Curriculum and were designed for Level-1 learners. The Second Foreign Language Curriculum is divided into four phases. The design concept was derived from the Common European Framework of Reference for Language (CEFR). The achievement of goals is presented in "Can-do" statements which emphasize the cultivation of learning effectiveness and application ability. The first stage is "Level-1," which is the beginner novice level of language learning. As far as Japanese language learning is concerned, the goal is to learn to recognize the pronunciation of the kana and to understand and use simple basic phrases needed for simple interactions and communication. The teaching activity design adheres to the spirit of the curriculum; furthermore, it invokes the second language acquisition theory. In addition to learning new vocabulary, teaching activities applied the vocabulary students had already learned for basic communication, and were designed to be flexible. As a result, learners gave positive evaluations of the teaching activities. It is hoped that the results of this exploratory research will provide a reference for the design of future activities.
