The Corpus of Spontaneous Japanese: Its design and evaluation [30] is a dataset of spontaneous Japanese speech.

A panel data set for use in cross-cultural analyses of aging, health, and well-being between the U.S. and Japan. The questionnaires were designed to be partially comparable to many surveys of the aged, including Americans'' Changing Lives; 1984 National Health Interview Survey Supplement on Aging; Health and Retirement Study (HRS), and Well-Being Among the Aged: Personal Control and Self-Esteem (WBA). NSJE questionnaire topics include: * Demographics (age, sex, marital status, education, employment) * Social Integration (interpersonal contacts, social supports) * Health Limitations on daily life and activities * Health Conditions * Health Status (ratings of present health) * Level of physical activity * Subjective Well-Being and Mental Health Status (life satisfaction, morale), * Psychological Indicators (life events, locus of control, self-esteem) * Financial situation (financial status) * Memory (measures of cognitive functioning) * Interviewer observations (assessments of respondents) The NSJE was based on a national sample of 2,200 noninstitutionalized elderly aged 60+ in Japan. This cohort has been interviewed once every 3 years since 1987. To ensure that the data are representative of the 60+ population, the samples in 1990 and 1996 were refreshed to add individuals aged 60-62. In 1999, a new cohort of Japanese adults aged 70+ was added to the surviving members of previous cohorts to form a database of 3,990 respondents 63+, of which some 3,000 were 70+. Currently a 6-wave longitudinal database (1987, 1990, 1993, 1996, 1999, & 2002) is in place; wave 7 began in 2006. Data Availability: Data from the first three waves of the National Survey of the Japanese Elderly are currently in the public domain and can be obtained from ICPSR. Additional data are being prepared for future public release. * Dates of Study: 1987-2006 * Study Features: Longitudinal, International * Sample Size: ** 1987: 2,200 ** 1990: 2,780 ** 1993: 2,780 ** 1996: ** 1999: 3,990 ** 2002: ** 2006: Links: * 1987 (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/06842 * 1990 (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/03407 * 1993 (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/04145 * 1996 (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/26621

The gravity station data (4,381 records) were compiled by the Japanese Oceanographic Data Center. This data base was received in July 1988. The data are in the 'MGD77' exchange format. Principal gravity parameters include Free-air Anomalies and Observed gravity corrected for Eotvos, drift, and tares. The observed gravity values are referenced to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. The data are randomly distributed within the boundaries of Japan.

This ranking displays the results of the worldwide Made-In-Country Index 2017, a survey conducted to show how positively products "made in..." are perceived in various countries all over the world. During this survey, all respondents (100 percent) from Vietnam perceived products made in Japan as "slightly positive" or "very positive".

This corpus comprises 2,000 Japanese place names uttered by 200 speakers of different dialects, ages and various educational levels, recorded over 4 channels. Speech samples are stored as a sequence of 16-bit 48kHz WAV for 3.93 hours of speech per channel. The total capacity of the data is 3.96 Gb. Each speaker read 10 items. Text files are stored in Unicode format. All data have been proofread manually. The corpus aims to be applied to the testing and telephone natural speech recognition system. This corpus is partly included in ELRA-S0228-54.

The majority of Japanese consumers in Japan, more than ** percent, have not used a recurring service recently, as revealed in a survey conducted in January 2025. The most commonly used subscription service was of the flat-rate model, which allows unlimited-use of online services and digital content as long as it remains within service terms.

The market size of digital publications in Japan was estimated at 566 billion Japanese yen in 2024, which was an increase of 30.9 billion yen compared to the previous year. Digital publishing and print publishing together constitute the larger publishing market.

United States Imports from Japan was US$152.07 Billion during 2024, according to the United Nations COMTRADE database on international trade. United States Imports from Japan - data, historical chart and statistics - was last updated on September of 2025.
