基礎を固める

You can use this phrase for almost any skill-based activity. Are you learning a new language? You are 基礎を固める by mastering the alphabet. Are you starting a business? You do it by finishing your market research. To use it, simply place the activity before the phrase. For example, テニスの基礎を固める means you are drilling the basic swings. It sounds diligent and professional. It shows you are a serious person who values quality.

Use this in a meeting when discussing a new project. It shows you want to be thorough. Use it with a coach when you feel your form is off. It is great for pep talks with friends who are frustrated with slow progress. You might say it to yourself when you feel like skipping the boring stuff. It is perfect for New Year's resolutions too. It signals a fresh, grounded start.

Don't use this for things that are already finished. It is a process-oriented phrase. Also, avoid using it for purely creative or chaotic tasks. You wouldn't really say it about 'solidifying the foundation' of a spontaneous party. It is also a bit too heavy for very minor tasks. Don't say it about making a sandwich unless you are a professional chef. It implies a significant journey ahead.

Japan has a deep culture of 'Kata' or forms. Think of martial arts or tea ceremonies. In these traditions, you might practice one single movement for years. This is the ultimate form of 基礎を固める. There is a belief that true mastery only comes after the basics are second nature. This philosophy carries over into schools and companies. Japanese people often value a slow, steady start over a fast, sloppy one. It is a mark of a reliable person.

You will often hear 基礎固め (kiso-gatame) as a noun. People might say 基礎固めが大事だ (the foundation-solidifying is important). Another similar one is 土台を築く (dodai o kizuku), which means to build a base. However, 固める (to harden) feels more like you are reinforcing something that is already there. It sounds more active and intentional. You are turning soft dirt into hard rock.
