Changes

The situation is quite different in Japan where mobile hardware was much more developed, only loosely Java-based, and major video game developers were much more invested in creating unique and high-quality content that's most obscure and unpreserved, let alone emulated, today. Those are the very different [[wikipedia:Galapagos syndrome|Galapagos mobile phones]] (like NTT DoCoMo i-mode, DeNa, RoID...). Some of these games got ported to the inferior Western hardware but these are in the tiny minority.

While originally not intended for games (until its more advanced game-oriented API came), it became the ''de facto'' market standard for cell phone gaming - due in no small part to the SDK being free and without licensing costs.

:Project developing a full JVM implementation + Java ME 8 APIs. Full compatibility with old J2ME software and high portability are among its main goals. Under heavy development.

Originally a joint Nintendo-Nokia cellphone handheld hybrid project slated for 2005, Nintendo backed away from the project (and its plans for NES/Game Boy ports for mobile were repurposed for their Virtual Engine project). Nokia continued the project on their own anyways and released N-Gage on October 7, 2003, for <abbr title="$377.10 in 2018 money">$299</abbr> as the most powerful handheld of its time, that is up until the DS and PSP came along and ended Nokia's hopes at dominating the handheld gaming market. It had an ARM920T CPU at 104 MHz.

* NTT DoCoMo released <b>DoJa</b> (later renamed to Star), based on Java ME CLDC, but not MIDP. Applications come in the form of .JAR files accompained by a .JAM descriptor.

It is possible to develop applications that work both under ezplus, J-SKY and standard J2ME devices by using only MIDP1.0 APIs

Japanese mobile manufacturer NTT DoCoMo released [https://en.wikipedia.org/wiki/DoJa DoJa] (DoCoMo's Java) as part of their i-mode set of standards for mobile telephony. It is based on Java ME CLDC, but not MIDP. The profile received several updates, being later renamed to "Star". It was used on DoCoMo's mova and FOMA series of mobile phones, being first featured on the mova 503i from 2001.

DeNa (Mobage), Namco (Tales of Mobile) and Level-5 (RoiD) set up Steam-like game distribution portals specific to some cell-phone models yet i-mode based. The different names are to confuse dirty gaijin, probably.

===J-SKY===

J-PHONE had been purchased by Vodafone on 2001, which two years later took over the original branding renaming the carrier to Vodafone KK. The J-SKY technology became then known as "Vodafone Live!" and it was extended with the VSCL set of APIs.

On 2006, Vodafone KK was purchased by SoftBank Group, getting this technology rebranded again as "Yahoo! Keitai".
