MSX was a standardized computer system developed primarily by electronics manufacturers. At the time, each computer manufacturer had its own specifications, leading to common incompatibilities between different brands. MSX aimed to promote widespread adoption by unifying these specifications, allowing for common software and peripherals across manufacturers. There are four versions of MSX: MSX, MSX2, MSX2+, and MSX turboR.

Models like PC-8001, PC-6001, and PC-8801, among others. NEC was one of the leading Japanese computer manufacturers at the time and was referred to as one of the "Big Three" in the personal computer industry. PC-8800 series also gave rise to derivatives such as PC-88VA and PC-98DO.

MZ series (such as MZ-80K), X1, X1 Turbo, X68000 series, and others. SHARP was also one of the companies referred to as part of the "Big Three" in the personal computer industry at the time.

FM-8 (FUJITSU MICRO 8), FM-7, FM-77, FM-77AV, FM TOWNS and others. Although Fujitsu entered the personal computer market later than NEC and SHARP, the success of FM-8 helped establish the company as one of those referred to as the "Big Three" in the industry at the time.

This section covers "single-board microcomputers," which were bare-board computers that existed before and around the time personal computers and microcomputers were developed. Some models were sold not as finished products, but as "assembly kits." NEC's COMPO BS/80 and Adtec System Science's COMKIT series are also included here as single-board microcomputers that were sold in enclosures. Only major models distributed in Japan are included.

This section features major models that were distributed in Japan, including 8-bit personal computers made by domestic manufacturers such as MSX, NEC, Sharp, Fujitsu, Hitachi's Basic Master series, Toshiba's Pasopia, Sony's SMC series, Matsushita's JR series, Sord's M5 series, Sega's SC-3000, and Tomy's Pyuuta, as well as personal computers and single-board microcomputers. It also includes early computers sold in Japan by overseas manufacturers before domestic makers entered the market, such as Apple (Apple II), Commodore (PET 2001), and Tandy RadioShack (TRS-80). The 16-bit and 32-bit X68000 and FM TOWNS series are also covered.

(Although not "personal computers," this section covers products related to the "hobby computers" field.)
This section includes major home video game consoles released in Japan, focusing on key consoles primarily organized by their release periods, starting with Epoch's "TV Tennis." Please note that special color variants, design changes, and bundled software changes are not included.
