INTRODUCTION Japan National Tourism Organization informs that on May 2012, there are Indonesian tourists who visit Japan (HaloJepang, 2012). Most people, especially those who first come to Japan face problems. The problems include the difference of weather, culture, and language. Nihongo, or bahasa Jepang as Indonesian say, is a unique language. Nihongo uses four different writing systems; Kanji (Chinese characters),

4 Hiragana (phonetic alphabet for native words), Katakana (phonetic alphabet for foreign words), and Romaji (western alphabet use to write Japanese) (Facts about Japan, 2013). If we compare Nihongo and Bahasa we will find some different structures of sentences where Indonesian are not familiar with. The new comers to Japan have to study Nihongo prior to their departure. They usually have to bring bulky books which take space in their baggage. On the other hand, the development of telecommunication technology, especially mobile phone is fast. A new model of mobile phone appears every month. Ability of mobile technology in creating flexibility for users to communicate has caused the technology to change so rapidly in terms of number of users and the capabilities of the technology itself. Increase the ability of mobile phones has allowed to bring a variety of new functions as well as its primary function as a communication tool (Ridho, 2011). However, according to our searching in mobile phone software market, there is no application which provides information about Japan and Nihongo in Bahasa Indonesia. There are several alternatives to solve the problem. First, Indonesian may bring Nihongo and manual tourism book wherever they go. However, it has disadvantage that is not simple because books need space to bring. Second, before Indonesian people come to Japan, they should study Nihongo. It will waste much time. Third, they bring a Nihongo application on their mobile phone. The third solution will be simple enough and we don t need to spend much time to study. They can open the application everywhere when they are in Japan or will be in Japan. This writing is about Nihongo application development to solve the aforementioned problems on Android platform. The writer use android mobile because IDC reports that on September 13 th, 2012 Android is the most famous smart phone operating system in Indonesia (HL, 2012). LITERATURE REVIEW

5 Aryani (2012) said that mobile is all of activities that can be done in every time and everywhere without barrier. The development of information and technology makes everything can be done quickly and easily. In the education side, the use of good English is the main requirement which cannot be ignored, because can face the people s ability to use that language. English has also become international language that is used in any developed countries. English become compulsory lesson to study. In this research the writer tries to build an application which contains subjects, the example of the sentences, and the exercise. Lailasari, Kurniawati, Afriansyah (2010) said that nowadays, learning media uses book. Other media that can be used in the teaching learning process is internet. Today internet is one of people needs. This research explained how to make Japanese language web E-learning for beginners by using PHP and MySQL. The purpose of making the website is to make people learn through the web instead of using book. The web contains hiragana, katakana, particle and making sentence. The web contains quiz or exercise that can be done by user. Nadira (2011) discusses about making an application that can be run on Android platform. They made Italian language learning application on the Android platform, where by using this application, the user can learn how to understand and test their Italian language skills. The application can ease how to learn Italian language with features like subject matter, and test the user s skill with exercise features without restricting the dimension so can help Italian language learning process.

This system will provide complete information on the tourism map of the location of objects that exist in Malang regency, travel guides to the tourists as tourist information, hotel, restaurant and

Development Life Cycle Models can be described in a phase in Figure 1. Figure 1 Code and Fix Models Diagram Code and Fix Method contains some step to complete the life cycle, which are conceptual, code and fix, and release. In conceptual step, the writer collects the data and designs the general layout. After designing the application, then the writer goes to code the program.
