Where is your traffic currently coming from?
Your store looks good, but I can't see any detail showing why someone should browse further. What sets your store apart from others? What are your unique selling points?
Also, on the homepage, there are a large number of products listed. I would condense this down to a few products (recently added, top rated, etc.) or remove them entirely. The job of the homepage is to convince people they're in the right place, and let them start to find what they are looking for.
Hope that helps - Gareth
Are you trying to focus on the Japanese market or USA market ? If USA market I'd change your website to be in USD and focus on that. At the moment I think you would have a lot of trouble converting anyone from the top five countries while main currency is set up in JPY

Overall I think your shopify store looks pretty good, But I noticed a couple of things that you might consider adding.
You might consider adding a sense of urgency. Imagine you are a customer browsing an online store. Maybe you are ready to buy maybe you aren't. But there is a good chance you aren't in the buying mood at the moment. If you add a sense of urgency to your store it can help more of your customers to buy, and have them buy faster. One way you can do so is by adding https://apps.shopify.com/better-countdown .
After looking I couldn't find a FAQ section. Adding an FAQ section to your store can help your customer more easily be able to find a solution to their problems without asking you. This will help long into the future so you don't need to spend so much time on customer support
Another thing you might want to add is a blog. A blog could be used to drive more traffic to your store, and you could also use it to recommend potential products that your customer could buy.
Did you think about adding social media links. Adding social media for your store can help people realize that they are dealing with a real person and organization and not just some faceless store
After looking I couldn't find reviews. If you add reviews it will help keep your customers on your site. If your customer needs to leave your site to do research on a product they might not come back, adding reviews can help with that.
An important thing I couldn't find is an always visible buy button. One of the biggest reasons people don't buy from online stores is because it's a hassle to checkout. We want to be able to reduce all friction that could potentially cause a customer not to buy. I recommend adding https://apps.shopify.com/better-sticky-checkout-button-increase-your-sales to your site. It's an app that will make your buy button always visible. If they buy button isn't always visible on your site, your customer will have a hard time trying to buy from you. And even if they still are able to checkout, it can go a long way in helping them have a positive experience on your site.
Overall your store looks really good, I think with just a little bit of time and effort you'll be able to create a really awesome store!
