Koikatsu Sunshine Gameplay
Following the already-established world of Koikatsu, in Sunshine, you will meet and date all the previous girls from Koikatsu Party, including DLC characters and even completely new ones, that together make a total of 40 characters with each having their own unique personality and voice lines.
Instead of a school setting, this time around players will be enjoying roaming about a tropical island somewhere in the southern part of Japan. The girls are enjoying an exotic summer study tour as part of their way to get more accustomed to interacting with the opposite sex. It is your job as the only male around to provide company and help them to experience summer romance.
Through different dating mechanics borrowed from the previous game, as well as a few new ones, players build their relationships with girls of their liking till reaching a level of trust in which girls are comfortable having sex with the player. As two new dating features, Koikatsu Sunshine introduces Special Conversations and Oil Massage.
On top of a simplistic dating simulator in a tropical setting, you can look forward to creating your own female characters to populate the island, date, and have sex with. These self-made characters can also be shared between other players via an easy-to-use but powerful in-game online system.
Once there is no longer reason to continue playing the story mode, players can shift towards Koikatsu Sunshine’s free H-mode which provides unlimited sex between two chosen characters in a preferred setting. This is the sex simulation part of the game, one that is also utilized in the story mode, only with more freedom.
Story
Our protagonist of the story is a young man living on his own near his aunt who is a headmaster of a girl-only school. With a scheme to introduce her female students to boys with whom to practice social skills and maybe a little more than that, the aunt invites our protagonist to attend her school as the only male student. Thus the after-school Koikatsu Club is born!
After some time has passed and the girls have grown a little accustomed to talking to boys thanks to our protagonist, it is time for phase two of aunt’s plan to give the girls even more experience in the field of romance. As a summer study tour, It is time to head to a southern tropical island to capture that summer love experience!
Island spots
On the tropical island, there are over 20 locations to visit in which girls roam around interacting with each other and the environment. Naturally, all of the locations provide the ability to have sex.
As a new feature, Koikatsu Sunshine has implemented a day & night system in which players can do certain actions and experience specific events depending on the time of day.
A few of the local attractions, visit a store to purchase sex items, or show your prayer at a roadside Shinto shrine to receive good luck with a chance of mysterious effects as a result.
Dating
This time around, girls are interested to talk about the island and its culture with you. Through conversation, you can deepen your relationship with them and eventually do all kinds of dirty stuff. Besides mundane conversation, certain actions can reward players with special kinds of conversation options.
You can request girls to walk and follow you around, have dinner with you, and more. But just like you have needs and desires, the girls are also capable of approaching you with their own requests that you may accept or refuse. Go on dates around the island, like shopping, playing table tennis, and simply just relaxing on a veranda, just to name a few.
Special conversations (New)
As a new dating feature in Koikatsu Sunshine, players can discover conversation pieces in the world. Once acquired, new conversation options highlighted with special colors appear when talking to girls. For example, you may find a wild cat and later talk about this discovery with your date. By simply having a conversation, players can receive special actions and even locations to have dates in.
Oil Massage (New)
Enjoy giving your girls an oil massage. Not only are oil massages a new way for Koikatsu to provide erotic content, but they also have a chance to provide players with special actions and locations to have dates in as a reward.
Character personalities
Koikatsu Sunshine provides 40 unique personalities that can be assigned to any girl of your choosing. These personalities are not just small gimmicks but they entirely change a character’s behavior and voice lines during conversations and sex. Not only are players able to make their dream waifu using the character creator but they are also able to place a personality on them that actually corresponds to their appearance.
Out of the 40 personalities, 6 are brand new while the rest are from Koikatsu Party and its DLCs. Despite borrowing old personalities from previous titles, you can still expect to see plenty of brand new lines of fully voice-acted dialogue.
Characters’ personality is said to change once in love. Instead of a friendly tone of mundane chatter between friends, the characters’ tone of voice and way of acting changes to a sweeter one, similar to how lovers stereotypically tend to talk to each other.
Hentai content
In Koikatsu Sunshine there are over 130 sex positions, either unlockable through the story mode or free to use in H-mode. most of the adult content is focused on our male protagonist and his harem of horny schoolgirls. Whether there is lesbian content available upon launch is yet to be confirmed but it is safe to assume that by following the example of Koikatsu Party, such content would eventually find its way into Sunshine as well.
Players can enjoy having both vanilla and hardcore intercourse with the girls. Blowjobs, titjobs, footjobs, anal, threesomes, sex toys, and a lot more are included as options during sex. All of the areas which players can visit in story mode act as potential places to have sex, indoors and outdoors.
During the sex simulator, You are given 360° camera controls and the freedom to manipulate the scene to your liking. Move characters around, change sex position or character’s clothing, and more!
Koikatsu Sunshine Character Creator
Illusion has provided a free demo of Sunshine’s character maker, though unfortunately, it is region-blocked and only accessible in Japan. Anyone familiar with Koikatsu Party’s character maker already knows what to expect from Sunshine as it uses the exact same features and user interface, only with an exception of a light blue polish to help scream the summer beach vibe.
As is to be expected, Koikatsu Sunshine brings new clothing pieces, hairstyles, accessories, and a lot more to its character creator, thus allowing you to make even more amazing-looking characters than before. Many of the newly added options are inspired by summer and beach themes.
Those not familiar with Koikatsu’s character maker can learn more by viewing Koikatsu Party Review where there are demonstrations of the character maker at work.
Despite being a standalone title, Koikatsu Sunshine utilizes the original Koikatsu’s character data which gives players the ability to upload their characters from the original Koikatsu to Sunshine. For those still enjoying their time creating highly detailed characters in Koikatsu, worry not, your waifus will follow you to your next adventure!
Koikatsu Sunshine VR & Chara Studio
Just as was the case with the original Koikatsu, it has been confirmed that a VR feature will arrive in Koikatsu Sunshine at a later date, yet to be announced after launch. What comes to Chara Studio, the existing version will receive an update with Sunshine’s content added to it somewhere after launch.
For those yet unfamiliar with Chara Studio, it is a separate program coming with the Japanese version of Koikatsu, in which players can build their own worlds and scenes using all the assets seen in Koikatsu along with exclusive ones as well.

Koikatsu Sunshine English version
Even though Illusion has not provided any information on a possible localization of their latest game, this does not necessarily mean that one is not coming or already in the making. Just like with Koikatsu Party, there was no word of a translated version ever coming to the west, yet the game received an official English version from Illusion a year later since the game’s original release in Japan.
Illusion has always been hush-hush when it comes to communicating with its western audience. Up to this date, they still do not provide even the simplest communication channels for western fans to reach them. There is even an old statement from a representative of the company telling outsiders to stop contacting them about their products, for it is their own design and choice not to provide English customer support nor official channels to communicate with the western audience. The reason behind this decision remains unclear, but if one was to guess, it is not far-fetched to assume that for a very long time, Illusion has not seen monetary potential in tapping into the western market for more reasons than one, hence not caring to invest in it.
It was only once Steam began opening up for the idea of allowing adult games on their platform when Illusion made a move by offering their very first localized game: VR Kanojo. A little later, Koikatsu was released and would eventually be the second game from Illusion’s large library of products to receive a localized version, now known as Koikatsu Party. Since then Honey Select Unlimited and AI Shoujo have followed, along with even Koikatsu After Party DLC that for a while was thought to be something Illusion would not care to provide an official translation for. By observing Illusion’s recent history, one can learn that a localized version of Koikatsu Sunshine may very well be on the horizon!
Right now Koikatsu Sunshine will release as a Japanese exclusive next month (in August), but you can be sure to learn more about it and enjoy raw gameplay footage of its story mode and adult content once Koikatsu Sunshine becomes available, so stay tuned!
If you have not yet had the chance to get to know Koikatsu, you can familiarize yourself with the series by watching the Koikatsu Party Review which goes over the game’s story, dating system, character creator, and adult content — getting you up-to-speed to prepare to experience Koikatsu Sunshine, if you choose to skip Koikatsu Party, that is.
